      The purpose of this guide is to provide security configuration
      recommendations for Fedora Linux. Recommended settings for the basic 
      operating system are provided, as well as for many commonly-used services 
      that the system can host in a network environment.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
      <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
      The guide is intended for system administrators. Readers are
      assumed to possess basic system administration skills for Unix-like systems, as well as some
      familiarity with Red Hat's documentation and administration conventions. Some instructions
      within this guide are complex. All directions should be followed completely and with
      understanding of their effects in order to avoid serious adverse effects on the system and its
      security.

          Data transmitted over a network, whether wired or wireless, is
          susceptible to passive monitoring. Whenever practical solutions for encrypting such data
          exist, they should be applied. Even if data is expected to be transmitted only over a
          local network, it should still be encrypted. Encrypting authentication data, such as
          passwords, is particularly important. Networks of machines can and should be
          configured so that no unencrypted authentication data is ever transmitted between
          machines.</xccdf:description>

          The simplest way to avoid vulnerabilities in software is to avoid
          installing that software. The RPM Package Manager allows for careful management of the 
          set of software packages installed on a system. Installed software contributes to system 
          vulnerability in several ways. Packages that include setuid programs may provide local 
          attackers a potential path to privilege escalation. Packages that include network services 
          may give this opportunity to network-based attackers. Packages that include programs 
          which are predictably executed by local users (e.g. after graphical login) may provide 
          opportunities for trojan horses or other attack code to be run undetected. The number of 
          software packages installed on a system can almost always be significantly pruned to include only 
          the software for which there is an environmental or operational need.</xccdf:description>

          Several tools exist which can be effectively used to improve a
          system's resistance to and detection of unknown attacks. These tools can improve
          robustness against attack at the cost of relatively little configuration effort. In
          particular, this guide recommends and discusses the use of Iptables for host-based
          firewalling, SELinux for protection against vulnerable services, and a logging and
          auditing infrastructure for detection of problems.</xccdf:description>

          Grant the least privilege necessary for user accounts and

          systems to only those administrators who need to log into them in order to perform 
          administration tasks. Using SELinux also follows the principle of least privilege: 
          SELinux policy can conﬁne software to perform only actions on the system that are 
          speciﬁcally allowed. This can be far more restrictive than the actions permissible 
          by the traditional Unix permissions model.</xccdf:description>

          security exploit are accompanied with a patch (or source code that fixes the problem). 
          This patch is then applied to the Fedora package and tested and released as an errata update. 
          However, if an announcement does not include a patch, a developer first works with the maintainer 
          of the software to fix the problem. Once the problem is fixed, the package is tested 
          and released as an errata update.

            The yum command line tool is used to install and update software
            packages. The system also provides package management service called PackageKit
            that allows the session users to manage packages in a secure way. There are several
            graphical utilities designed for installing, updating and removing packages on your 
            system that use PackageKit API. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            It is recommended to use these mechanisms to keep systems up to date with the latest
            security patches.

          The AIDE (Advanced Intrusion Detection Environment) software is
          included with the system to provide software integrity checking. It is designed to be a
          replacement for the well-known Tripwire integrity checker. Integrity checking cannot
          <xhtml:em xmlns:xhtml="http://www.w3.org/1999/xhtml">prevent</xhtml:em>
          intrusions into your system, but can detect that they have occurred.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          Any integrity checking software should be configured before
          the system is deployed and able to provides services to users. Ideally, the integrity
          checking database would be built before the system is connected to any network, though
          this may prove impractical due to registration and software updates.

            Requirements for software integrity checking should be defined

            used. As such, a general strategy for implementing integrity checking is provided, but
            precise recommendations (such as to check a particular file) cannot be. Documentation
            for AIDE, including the quick-start on which this advice is based, is available in

        Traditional Unix security relies heavily on file and directory
        permissions to prevent unauthorized users from reading or modifying files to which they
        should not have access. Adhere to the principle of least privilege — configure each file,
        directory, and filesystem to allow only the access needed in order for that file to serve

        However, Linux systems contain a large number of files, so
        it is often prohibitively time-consuming to ensure that every file on a machine has exactly
        the permissions needed. This section introduces several permission restrictions which are
        almost always appropriate for system security, and which are easy to test and

        is intended to be run repeatedly, with the name of each local partition substituted for
        <xhtml:em xmlns:xhtml="http://www.w3.org/1999/xhtml">PART</xhtml:em>

                      <xccdf:description xml:lang="en">
            The system's default desktop environment, GNOME, runs the
            program gnome-volume-manager to mount devices and removable media (such as DVDs, CDs and
            USB flash drives) whenever they are inserted into the system. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The system's capabilities for automatic mounting should be configured to match whatever 
            is defined by security policy. Disabling USB storage as described in Section 2.2.2.2.1 
            will prevent the use of USB storage devices, but this step can also be taken as an 
            additional layer of prevention and to prevent automatic mounting of CDs and DVDs if
            required. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Particularly for kiosk-style systems, where users should
            have extremely limited access to the system, more detailed information can be found in
            Red Hat Desktop: Deployment Guide. The gconf-editor program, available in an RPM of the
            same name, can be used to explore other settings available in the GNOME environment.

            When the so-called 'sticky bit' is set on a directory, only the
            owner of a given file may remove that file from the directory. Without the sticky bit,
            any user with write access to a directory may remove any file in the directory. Setting
            the sticky bit prevents users from removing each other's files. In cases where there is
            no reason for a directory to be world-writable, a better solution is to remove that
            permission rather than to set the sticky bit. However, if a directory is used by a
            particular application, consult that application's documentation instead of blindly
            changing modes.</xccdf:description>

            Data in world-writable files can be modified by any user on the
            system. In almost all circumstances, files can be configured using a combination of user
            and group permissions to support whatever legitimate access is needed without the risk
            caused by world-writable files. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            It is generally a good idea to
            remove global (other) write access to a file when it is discovered. However, check with
            documentation for specific applications before making changes. Also, monitor for
            recurring world-writable files, as these may be symptoms of a misconfigured application
            or user account.

            A core dump file is the memory image of an executable program
            when it was terminated by the operating system due to errant behavior. In most cases,
            only software developers would legitimately need to access these files. The core dump
            files may also contain sensitive information, or unnecessarily occupy large amounts of
            disk space. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            By default, the system sets a soft limit to stop the
            creation of core dump files for all users. This is accomplished in /etc/profile with the
            line: ulimit -S -c 0 &gt; /dev/null 2&gt;&amp;1 However, compliance with this
            limit is voluntary; it is a default intended only to protect users from the annoyance of
            generating unwanted core files. Users can increase the allowed core file size up to the
            hard limit, which is unlimited by default. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Once a hard limit is set
            in /etc/security/limits.conf, the user cannot increase that limit within his own
            session. If access to core dumps is required, consider restricting them to only certain
            users or groups. See the limits.conf man page for more
            information. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The core dumps of setuid programs are further
            protected. The sysctl variable fs.suid_dumpable controls whether the kernel allows core
            dumps from these programs at all. The default value of 0 is recommended.

            ExecShield comprises a number of kernel features to provide
            protection against buffer overflows. These features include random placement of the
            stack and other memory regions, prevention of execution in memory that should only hold
            data, and special handling of text buffers. This protection is enabled by default, but
            the sysctl variables kernel.exec-shield and kernel.randomize va space should be checked
            to ensure that it has not been disabled. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            ExecShield uses the
            segmentation feature on all x86 systems to prevent execution in memory higher than a
            certain address. It writes an address as a limit in the code segment descriptor, to
            control where code can be executed, on a per-process basis. When the kernel places a
            process's memory regions such as the stack and heap higher than this address, the
            hardware prevents execution there. However, this cannot always be done for all memory
            regions in which execution should not occur, so follow guidance in Section 2.2.4.4 to
            further protect the system.

            Disable (XD). This ability can help prevent exploitation of buffer overflow
            vulnerabilities and should be activated whenever possible. Extra steps must be taken to
            ensure that this protection is enabled, particularly on 32-bit x86 systems. Other
            processors, such as Itanium and POWER, have included such support since inception and

        In traditional Unix security, if an attacker gains shell access to

        has access. Therefore, making it more difficult for unauthorized people to gain shell access
        to accounts, particularly to privileged accounts, is a necessary part of securing a system.

          Conventionally, Unix shell accounts are accessed by providing a
          username and password to a login program, which tests these values for correctness using
          the /etc/passwd and /etc/shadow files. Password-based login is vulnerable to guessing of
          weak passwords, and to sniffing and man-in-the-middle attacks against passwords entered
          over a network or at an insecure console. Therefore, mechanisms for accessing accounts by
          entering usernames and passwords should be restricted to those which are operationally

            Direct root logins should be allowed only for
            emergency use. In normal situations, the administrator should access the system via a
            unique unprivileged account, and use su or sudo to execute privileged commands.
            Discouraging administrators from accessing the root account directly ensures an audit
            trail in organizations with multiple administrators. Locking down the channels through
            which root can connect directly reduces opportunities for password-guessing against the
            root account. The login program uses the file /etc/securetty to determine which
            interfaces should allow root logins. The virtual devices /dev/console and /dev/tty*
            represent the system consoles (accessible via the Ctrl-Alt-F1 through Ctrl-Alt-F6
            keyboard sequences on a default installation). The default securetty file also contains
            /dev/vc/*. These are likely to be deprecated in most environments, but may be retained
            for compatibility. Root should also be prohibited from connecting via network protocols.
            See Section 3.5 for instructions on preventing root from logging in via SSH.</xccdf:description>

            The sudo command allows fine-grained control over
            which users can execute commands using other accounts. The primary benefit of sudo when
            configured as above is that it provides an audit trail of every command run by a
            privileged user. It is possible for a malicious administrator to circumvent this
            restriction, but, if there is an established procedure that all root commands are run
            using sudo, then it is easy for an auditor to detect unusual behavior when this
            procedure is not followed. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Editing /etc/sudoers by hand can be dangerous, since a configuration error may make it 
            impossible to access the root account remotely. The recommended means of editing this 
            file is using the visudo command, which checks the file's syntax for correctness before 
            allowing it to be saved.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Note that sudo allows any attacker who gains access to the password of an administrator 
            account to run commands as root. This is a downside which must be weighed against the 
            benefits of increased audit capability and of being able to heavily restrict the use of 
            the high-value root password (which can be logistically difficult to change often). As 
            a basic precaution, never use the NOPASSWD directive, which would allow anyone with 
            access to an administrator account to execute commands as root without knowing the 
            administrator's password. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The sudo command has many options which can be used to further customize its behavior. 
            See the sudoers(5) man page for details.</xccdf:description>

            In general, the best practice solution for auditing use of the root account is to restrict

            in almost all cases. Some sites choose to have more than one account with UID 0 in order

            Users should be forced to change their passwords, in order to decrease the utility of
            compromised passwords. However, the need to change passwords often should be balanced
            against the risk that users will reuse or write down passwords if forced to change them
            too often. Forcing password changes every 90-360 days, depending on the environment, is
            recommended. Set the appropriate value as PASS_MAX_DAYS and apply it to existing
            accounts with the -M flag. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            The PASS_MIN_DAYS (-m) setting prevents password changes for 7 days after the first 
            change, to discourage password cycling. If you use this setting, train users to contact 
            an administrator for an emergency password change in case a new password becomes

          The access control policies which can be enforced by standard

            Identify all user accounts on the system which correspond to
            human users. Depending on your system configuration, this may be all entries in
            /etc/passwd with UID values of at least 500. Once, you have identified such a set of
            users, create a group named usergroup (substitute some name appropriate to your
            environment) and populate it with each human user: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:code xmlns:xhtml="http://www.w3.org/1999/xhtml"># groupadd usergroup <xhtml:br/>
            # usermod -G usergroup human1 <xhtml:br/>
            # usermod -G usergroup human2 ... <xhtml:br/>
            # usermod -G usergroup humanN <xhtml:br/></xhtml:code>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Then modify your procedure for creating new user accounts by adding -G usergroup to the 
            set of flags with which useradd is invoked, so that new human users will be placed in 
            the correct group by default. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Creating a group of human users does not, by itself, enhance
            system security. However, as you work on securing your system, you will often find
            commands which never need to be run by system accounts, or which are only ever needed by
            users logged into the graphical console (which should only ever be available to human
            users, even on workstations). Once a group of users has been created, it is easy to
            restrict access to a given command, for instance /path/to/graphical/command , to
            authorized users: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:code xmlns:xhtml="http://www.w3.org/1999/xhtml"># chgrp usergroup /path/to/graphical/command <xhtml:br/>
            # chmod 750 /path/graphical/command <xhtml:br/></xhtml:code>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Without a group of human users, it is necessary to restrict

                    <xccdf:description xml:lang="en">
          PAM, or Pluggable Authentication Modules, is a system which
          implements modular authentication for Linux programs. PAM is well-integrated into Linux's
          authentication architecture, making it difficult to remove, but it can be configured to
          minimize your system's exposure to unnecessary risk. This section contains guidance on how
          to accomplish that, and how to ensure that the modules used by your PAM configuration do
          what they are supposed to do. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          PAM is implemented as a set of shared objects which are
          loaded and invoked whenever an application wishes to authenticate a user. Typically, the
          application must be running as root in order to take advantage of PAM. Traditional
          privileged network listeners (e.g. sshd) or SUID programs (e.g. sudo) already meet this
          requirement. An SUID root application, userhelper, is provided so that programs which are
          not SUID or privileged themselves can still take advantage of PAM. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          PAM looks in the
          directory /etc/pam.d for application-specific configuration information. For instance, if
          the program login attempts to authenticate a user, then PAM's libraries follow the
          instructions in the file /etc/ pam.d/login to determine what actions should be taken. 
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>One
          very important file in /etc/pam.d is /etc/pam.d/system-auth. This file, which is included
          by many other PAM configuration files, defines 'default' system authentication measures.
          Modifying this file is a good way to make far-reaching authentication changes, for
          instance when implementing a centralized authentication service.
        </xccdf:description>
                    <xccdf:warning xml:lang="en">
          Be careful when making changes to PAM's configuration files. The syntax for these files 
          is complex, and modifications can have unexpected consequences.1 The default 
          configurations shipped with applications should be sufficient for most users.

          Running authconfig or system-config-authentication will re-write the PAM configuration

            The default pam_cracklib PAM module provides strength checking

            similar to dictionary words, are of at least a certain length, are not the previous
            password reversed, and are not simply a change of case from the previous password.  It

            The pam_tally2 PAM module provides the capability to lock out
            user accounts after a number of failed login attempts. Its documentation is available in
            /usr/share/doc/pam-version/txts/README.pam_tally2. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            If locking out accounts after a number of incorrect login attempts is required by your 
            security policy, implement use of pam_tally2.so for the relevant PAM-aware programs 
            such as login, sshd, and vsftpd. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Find the following line in /etc/pam.d/system-auth: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            and then change it so that it reads as follows: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            In the same file, comment out or delete the lines: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            To enforce password lockout, add the following to the individual programs' 
            configuration files in /etc/pam.d. First, add to end of the auth lines: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            auth required pam_tally2.so deny=5 onerr=fail <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Second, add to the end of the account lines: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Adjust the deny argument to conform to your system security policy. The pam_tally2
            utility can be used to unlock user accounts as follows: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

                      <xccdf:warning xml:lang="en">
            Locking out user accounts presents the risk of a denial-of-service attack. The security 
            policy regarding system lockout must weigh whether the risk of such a denial-of-service 
            attack outweighs the benefits of thwarting password guessing attacks. The pam_tally2 
            utility can be run from a cron job on a hourly or daily basis to try and offset this 
            risk.

            In order to deny access to a service SVCNAME via PAM, edit the
            file /etc/pam.d/SVCNAME . Prepend this line to the beginning of the file: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            Under most circumstances, there are better ways to disable a service than to
            deny access via PAM. However, this should suffice as a way to quickly make a service
            unavailable to future users (existing sessions which have already been authenticated,
            are not affected). The requisite tag tells PAM that, if the named module returns
            failure, authentication should fail, and PAM should immediately stop processing the
            configuration file. The pam_deny.so module always returns failure regardless of its
            input.</xccdf:description>

                      <xccdf:description xml:lang="en">
            If your environment has defined a group, usergroup containing
            all the human users of your system, restrict execution of the userhelper program to only
            that group: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:code xmlns:xhtml="http://www.w3.org/1999/xhtml"># chgrp usergroup /usr/sbin/userhelper <xhtml:br/>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The userhelper program provides authentication for graphical services which must run 
            with root privileges, such as the system-config- family of graphical configuration 
            utilities. Only human users logged into the system console are likely to ever have a 
            legitimate need to run these utilities. This step provides some protection against 
            possible flaws in userhelper's implementation, and against further privilege escalation 
            when system accounts are compromised. See Section 2.3.2.2 for more information on 
            creating a group of human users. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The userhelper program is configured by the files in /etc/security/console.apps/. Each 
            file specifies, for some program, what user the program should run as, and what program 
            should be executed after successful authentication. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Note: The configuration in /etc/security/console.apps/ is applied in
            combination with the PAM configuration of the service defined in /etc/pam.d/. First,
            userhelper determines what user the service should run as. (Typically, this will be
            root.) Next, userhelper uses the PAM API to allow the user who ran the program to
            attempt to authenticate as the desired user. The PAM API exchange is wrapped in a GUI if
            the application's configuration requests one.</xccdf:description>

          When a user logs into a Unix account, the system configures the
          user's session by reading a number of files. Many of these files are located in the user's
          home directory, and may have weak permissions as a result of user error or
          misconfiguration. If an attacker can modify or even read certain types of account
          configuration information, he can often gain full access to the affected user's account.
          Therefore, it is important to test and correct configuration file permissions for
          interactive accounts, particularly those of privileged users such as root or system
          administrators.</xccdf:description>

            The active path of the root account can be obtained by starting
            a new root shell and running: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            <xhtml:code xmlns:xhtml="http://www.w3.org/1999/xhtml"># echo $PATH <xhtml:br/></xhtml:code>
            This will produce a colon-separated list of directories in the path. For each directory 
            DIR in the path, ensure that DIR is not equal to a single . character. Also ensure that 
            there are no 'empty' elements in the path, such as in these examples: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            These empty elements have the same effect as a single . character. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            It is important to prevent root from executing unknown or untrusted programs, since such
            programs could contain malicious code. Therefore, root should not run programs installed
            by unprivileged users. Since root may often be working inside untrusted directories, the
            . character, which represents the current directory, should never be in the root path,
            nor should any directory which can be written to by an unprivileged or semi-privileged
            (system) user. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            With a default umask setting of 077, files and directories created by users will not be
            readable by any other user on the system. Users who wish to make specific files group-
            or world-readable can accomplish this using the chmod command. Additionally, users can
            make all their files readable to their group by default by setting a umask of 027 in
            their shell configuration files. If default per-user groups exist (that is, if every
            user has a default group whose name is the same as that user's username and whose only
            member is the user), then it may even be safe for users to select a umask of 007, making
            it very easy to intentionally share files with group s of which the user is a member. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            In addition, it may be necessary to change root's umask temporarily in order to install
            software or files which must be readable by other users, or to change the default umasks
            of certain service accounts such as the FTP user. However, setting a restrictive default
            protects the files of users who have not taken steps to make their files more available,
            and preventing files from being inadvertently shared.</xccdf:description>

            The BIOS (on x86 systems) is the first code to execute during
            system startup and controls many important system parameters, including which devices
            the system will try to boot from, and in which order. Assign a password to prevent any
            unauthorized changes to the BIOS configuration. The exact steps will vary depending on
            your machine, but are likely to include:<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:ol xmlns:xhtml="http://www.w3.org/1999/xhtml"><xhtml:li>Reboot the machine.</xhtml:li><xhtml:li>Press the appropriate key during the initial boot screen (F2 is typical)</xhtml:li><xhtml:li>Navigate the BIOS configuration menu to add a password.</xhtml:li></xhtml:ol>
            The exact process will be system-specific and the system's
            hardware manual may provide detailed instructions. This password should prevent
            attackers with physical access from attempting to change important parameters, such as
            those described in Sections 2.5.2.2.1 and 2.2.2.2.4. However, an attacker with physical
            access can usually clear the BIOS password. The password should be written down and
            stored in a physically-secure location, such as a safe, in the event that it is
            forgotten and must be retrieved.</xccdf:description>

            During the boot process, the boot loader is responsible for
            starting the execution of the kernel and passing options to it. The boot loader allows
            for the selection of different kernels – possibly on different partitions or media.
            Options it can pass to the kernel include 'single-user mode,' which provides root access
            without any authentication, and the ability to disable SELinux. To prevent local users
            from modifying the boot parameters and endangering security, the boot loader
            configuration should be protected with a password. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            If the system does not run X Windows, then the login shells can
            be configured to automatically log users out after a period of inactivity. The following
            instructions are not practical for systems which run X Windows, as they will close
            terminal windows in the X environment. For information on how to automatically lock
            those systems, see Section 2.3.5.6. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            To implement a 15-minute idle time-out for the
            default /bin/bash shell, create a new file tmout.sh in the directory /etc/profile.d with
            the following lines: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            readonly TMOUT <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            export TMOUT <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            To implement a 15-minute idle
            time-out for the tcsh shell, create a new file autologout.csh in the directory
            /etc/profile.d with the following line: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            set -r autologout 15 <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Similar actions should be taken for any other login shells used. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The example time-out here of 15 minutes should be
            adjusted to whatever your security policy requires. The readonly line for bash and the
            -r option for tcsh can be omitted if policy allows users to override the value. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The automatic shell logout only occurs when the shell is the foreground process. If, for
            example, a vi session is left idle, then automatic logout would not occur. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            When logging in through a remote connection, as with SSH, it may be more effective to set 
            the timeout value directly through that service. To learn how to set automatic timeout 
            intervals for SSH, see Section 3.5.2.3.</xccdf:description>

                    <xccdf:description xml:lang="en">
          A centralized authentication service is any method of maintaining
          central control over account and authentication data and of keeping this data synchronized
          between machines. Such services can range in complexity from a script which pushes
          centrally-generated password files out to all machines, to a managed scheme such as LDAP
          or Kerberos. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          If authentication information is not centrally managed, it quickly becomes
          inconsistent, leading to out-of-date credentials and forgotten accounts which should have
          been deleted. In addition, many older protocols (such as NFS) make use of the UID to
          identify users over a network. This is not a good practice, and these protocols should be
          avoided if possible. However, since most sites must still make use of some older
          protocols, having consistent UIDs and GIDs site-wide is a significant benefit. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          Centralized
          authentication services do have the disadvantage that authentication information must be
          transmitted over a network, leading to a risk that credentials may be intercepted or
          manipulated. Therefore, these services must be deployed carefully. The following
          precautions should be taken when configuring any authentication service: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:ul xmlns:xhtml="http://www.w3.org/1999/xhtml"><xhtml:li>Ensure that authentication information and any sensitive account information 
              are never sent over the network unencrypted.</xhtml:li><xhtml:li>Ensure that the root account has a local password, to allow recovery in case 
              of network outage or authentication server failure.</xhtml:li></xhtml:ul>
           This guide recommends
          the use of LDAP. Secure configuration of OpenLDAP for clients and servers is described in
          Section 3.12. Kerberos is also a good choice for a centralized authentication service, but
          a description of its configuration is beyond the scope of this guide. The NIS service is
          not recommended, and should be considered obsolete. (See Section 3.2.4.)</xccdf:description>

          System banners, which are typically displayed just before a login prompt, give
          out information about the service or the host's operating system. This might include the
          distribution name and the system kernel version, and the particular version of a network
          service. This information can assist intruders in gaining access to the system as it can
          reveal whether the system is running vulnerable software. Most network services can be

          warning to unauthorized users, and remind authorized users of their consent to monitoring.</xccdf:description>

                  <xccdf:description xml:lang="en">
        SELinux is a feature of the Linux kernel which can be used to guard
        against misconfigured or compromised programs. SELinux enforces the idea that programs
        should be limited in what files they can access and what actions they can take. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        The default
        SELinux policy, as configured on RHEL5, has been sufficiently developed and debugged that it
        should be usable on almost any Red Hat machine with minimal configuration and a small amount
        of system administrator training. This policy prevents system services — including most of
        the common network-visible services such as mail servers, ftp servers, and DNS servers —
        from accessing files which those services have no valid reason to access. This action alone
        prevents a huge amount of possible damage from network attacks against services, from
        trojaned software, and so forth. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        This guide recommends that SELinux be enabled using the
        default (targeted) policy on every Red Hat system, unless that system has requirements which
        make a stronger policy appropriate.</xccdf:description>

                    <xccdf:description xml:lang="en">
          In the traditional Linux/Unix security model, known as
          Discretionary Access Control (DAC), processes run under a user and group identity, and
          enjoy that user and group's access rights to all files and other objects on the system.
          This system brings with it a number of security problems, most notably: that processes
          frequently do not need and should not have the full rights of the user who ran them; that
          user and group access rights are not very granular, and may require administrators to
          allow too much access in order to allow the access that is needed; that the Unix
          filesystem contains many resources (such as temporary directories and world-readable
          files) which are accessible to users who have no legitimate reason to access them; and
          that legitimate users can easily provide open access to their own resources through
          confusion or carelessness. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          SELinux provides a Mandatory Access Control (MAC) system that
          greatly augments the DAC model. Under SELinux, every process and every object (e.g. file,
          socket, pipe) on the system is given a security context, a label which include detailed
          type information about the object. The kernel allows processes to access objects only if
          that access is explicitly allowed by the policy in effect. The policy defines transitions,
          so that a user can be allowed to run software, but the software can run under a different
          context than the user's default. This automatically limits the damage that the software
          can do to files accessible by the calling user — the user does not need to take any action
          to gain this benefit. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          For an action to occur, both the traditional DAC permissions must be
          satisifed as well as SELinux's MAC rules. If either do not permit the action, then it will
          not be allowed. In this way, SELinux rules can only make a system's permissions more
          restrictive and secure. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          SELinux requires a complex policy in order to allow all the
          actions required of a system under normal operation. Three such policies have been
          designed for use with RHEL5, and are included with the system. In increasing order of
          power and complexity, they are: targeted, strict, and mls. The targeted SELinux policy
          consists mostly of Type Enforcement (TE) rules, and a small number of Role-Based Access
          Control (RBAC) rules. It restricts the actions of many types of programs, but leaves
          interactive users largely unaffected. The strict policy also uses TE and RBAC rules, but
          on more programs and more aggressively. The mls policy implements Multi-Level Security
          (MLS), which introduces even more kinds of labels — sensitivity and category — and rules
          that govern access based on these. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          The remainder of this section provides guidance for the
          configuration of the targeted policy and the administration of systems under this policy.
          Some pointers will be provided for readers who are interested in further strengthening
          their systems by using one of the stricter policies provided with RHEL5 or in writing
          their own policy.</xccdf:description>

          Edit the file /etc/grub.conf. Ensure that
          the following arguments DO NOT appear on any kernel command line in the file: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          The directive SELINUX=enforcing enables SELinux at boot time. If SELinux is
          causing a lot of problems or preventing the system from booting, it is possible to boot
          into the warning-only mode SELINUX=permissive for debugging purposes. Make certain to
          change the mode back to enforcing after debugging, set the filesystems to be relabelled
          for consistency using the command touch /.autorelabel, and reboot. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          However, the RHEL5
          default SELinux configuration should be sufficiently reasonable that most systems will
          boot without serious problems. Some applications that require deep or unusual system
          privileges, such as virtual machine software, may not be compatible with SELinux in its
          default configuration. However, this should be uncommon, and SELinux's application support
          continues to improve. In other cases, SELinux may reveal unusual or insecure program
          behavior by design. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          The directive SELINUXTYPE=targeted configures SELinux to use the
          default targeted policy. See Section 2.4.6 if a stricter policy is appropriate for your
          site. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          The SELinux boot mode specified in /etc/selinux/config can be overridden by
          command-line arguments passed to the kernel. It is necessary to check grub.conf to ensure
          that this has not been done and to protect the bootloader as described in Section 2.3.5.2.</xccdf:description>

            Is there a mission-critical reason to allow users to view
            SELinux denial information using the sealert GUI? If not, disable the service and remove

            The setroubleshoot
            service is a facility for notifying the desktop user of SELinux denials in a
            user-friendly fashion. SELinux errors may provide important information about intrusion
            attempts in progress, or may give information about SELinux configuration problems which
            are preventing correct system operation. In order to maintain a secure and usable
            SELinux installation, error logging and notification is necessary. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            However,
            setroubleshoot is a service which has complex functionality, which runs a daemon and
            uses IPC to distribute information which may be sensitive, or even to allow users to
            modify SELinux settings, and which does not yet implement real authentication
            mechanisms. This guide recommends disabling setroubleshoot and using the kernel audit
            functionality to monitor SELinux's behavior. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            In addition, since setroubleshoot
            automatically runs client-side code whenever a denial occurs, regardless of whether the
            setroubleshootd daemon is running, it is recommended that the program be removed
            entirely unless it is needed.</xccdf:description>

            restorecond may be used to monitor problematic files for context problems, or system
            administrators may be trained to check file contexts of newly-created files using the

          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          If you suspect that a permission error or other failure may be caused
          by SELinux (and are certain that misconfiguration of the traditional Unix permissions are
          not the cause of the problem), search the audit logs for AVC events: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:code xmlns:xhtml="http://www.w3.org/1999/xhtml"># ausearch -m AVC,USER_AVC -sv no <xhtml:br/></xhtml:code>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          The output of this command will be a set of events. The timestamp,
          along with the comm and pid fields, should indicate which line describes the problem. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          Look
          up the context under which the process is running. Assuming the process ID is PID , find
          the context by running: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:code xmlns:xhtml="http://www.w3.org/1999/xhtml"># ps -p PID -Z <xhtml:br/></xhtml:code>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          The AVC denial message should identify the
          offending file or directory. The name field should contain the filename (not the full
          pathname by default), and the ino field can be used to search by inode, if necessary.
          Assuming the file is FILE , find its SELinux context: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:code xmlns:xhtml="http://www.w3.org/1999/xhtml"># ls -Z FILE <xhtml:br/></xhtml:code>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          An administrator should
          suspect an SELinux misconfiguration whenever a program gets a 'permission denied' error
          but the standard Unix permissions appear to be correct, or a program fails mysteriously on
          a task which seems to involve file access or network communication. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          As described in
          Section 2.4.1, SELinux augments each process with a context providing detailed type
          information about that process. The contexts under which processes run may be referred to
          as subject contexts. Similarly, each filesystem object is given a context. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          The targeted
          policy consists of a set of rules, each of which allows a subject type to perform some
          operation on a given object type. The kernel stores information about these access
          decisions in an structure known as an Access Vector Cache (AVC), so authorization
          decisions made by the system are audited with the type AVC. It is also possible for
          userspace modules to implement their own policies based on SELinux, and these decisions
          are audited with the type USER_AVC. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          AVC denials are logged by the kernel audit facility
          (see Section 2.6.2 for configuration guidance on this subsystem) and may also be visible
          via setroubleshoot. This guide recommends the use of the audit userspace utilities to find
          AVC errors. It is possible to manually locate these errors by looking in the file
          /var/log/audit/audit.log or in /var/log/messages (depending on the syslog configuration in
          effect), but the ausearch tool allows finegrained searching on audit event types, which
          may be necessary if system call auditing is enabled as well. The command line above tells
          ausearch to look for kernel or userspace AVC messages (-m AVC,USER AVC) where the access
          attempt did not succeed (-sv no). <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          If an AVC denial occurs when it should not have, the
          problem is generally one of the following: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:ul xmlns:xhtml="http://www.w3.org/1999/xhtml"><xhtml:li>The program is running with the wrong subject
              context. This could happen as a result of an incorrect context on the program's executable
              file, which could happen if 3rd party software is installed and not given appropriate
              SELinux file contexts. </xhtml:li><xhtml:li>The file has the wrong object context because the current file's
              context does not match the specification. This can occur when files are created or
              modified in certain ways. It is not atypical for configuration files to get the wrong
              contexts after a system configuration change performed by an administrator. To repair the
              file, use the command: <xhtml:br/>
              <xhtml:br/>
              <xhtml:code># restorecon -v FILE <xhtml:br/></xhtml:code>
              <xhtml:br/>
              This should produce output indicating that the
              file's context has been changed. The /usr/bin/chcon program can be used to manually change
              a file's context, but this is problematic because the change will not persist if it does
              not agree with the policy-defined contexts applied by restorecon.</xhtml:li><xhtml:li>The file has the wrong
              object context because the specification is either incorrect or does not match the way the
              file is being used on this system. In this case, it will be necessary to change the system
              file contexts. <xhtml:br/>
              <xhtml:br/>
              Run the system-config-selinux tool, and go to the 'File Labeling' menu.
              This will give a list of files and wildcards corresponding to file labelling rules on the
              system. Add a rule which maps the file in question to the desired context. As an
              alternative, file contexts can be modified from the command line using the semanage(8)
              tool.</xhtml:li><xhtml:li>The program and file have the correct contexts, but the policy should allow some
              operation between those two contexts which is currently not allowed. In this case, it will
              be necessary to modify the SELinux policy. <xhtml:br/>
              <xhtml:br/>
              Run the system-config-selinux tool, and go to
              the 'Boolean' menu. If your configuration is supported, but is not the Red Hat default,
              then there will be a boolean allowing real-time modification of the SELinux policy to fix
              the problem. Browse through the items in this menu, looking for one which is related to
              the service which is not working. As an alternative, SELinux booleans can be modified from
              the command line using the getsebool(8) and setsebool(8) tools. <xhtml:br/>
              <xhtml:br/>
              If there is no boolean, it
              will be necessary to create and load a policy module. A simple way to build a policy
              module is to use the audit2allow tool. This tool can take input in the format of AVC
              denial messages, and generate syntactically correct Type Enforcement rules which would be
              sufficient to prevent those denials. For example, to generate and display rules which
              would allow all kernel denials seen in the past five minutes, run: <xhtml:br/>
              <xhtml:br/>
              <xhtml:code># ausearch -m AVC -sv no -ts recent | audit2allow <xhtml:br/></xhtml:code>
              <xhtml:br/>
              It is possible to use audit2allow to directly create a module
              package suitable for loading into the kernel policy. To do this, invoke audit2allow with
              the -M flag: <xhtml:br/>
              <xhtml:br/>
              <xhtml:code># ausearch -m AVC -sv no -ts recent | audit2allow -M localmodule <xhtml:br/></xhtml:code>
              <xhtml:br/>
              If this is
              successful, several lines of output should appear. Review the generated TE rules in the
              file localmodule .te and ensure that they express what you wish to allow. <xhtml:br/>
              <xhtml:br/>
              The file
              localmodule .pp should also have been created. This file is a policy module package that
              can be loaded into the kernel. To do so, use system-config-selinux, go to the 'Policy
              Module' menu and use the 'Add' button to enable your module package in SELinux, or load it
              from the command line using semodule(8): <xhtml:br/>
              <xhtml:br/>
              <xhtml:code># semodule -i localmodule .pp <xhtml:br/></xhtml:code>
              <xhtml:br/>
              Section 45.2 of [9] covers this procedure in detail.</xhtml:li></xhtml:ul></xccdf:description>

          The recommendations up to this point have discussed how to
          configure and maintain a system under the default configuration of the targeted policy,
          which constrains only the actions of daemons and system software. This guide strongly
          recommends that any site which is not currently using SELinux at all transition to the
          targeted policy, to gain the substantial security benefits provided by that policy.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          However, the default policy provides only a subset of the full security gains available
          from using SELinux. In particular, the SELinux policy is also capable of constraining the
          actions of interactive users, of providing compartmented access by sensitivity level (MLS)
          and/or category (MCS), and of restricting certain types of system actions using booleans
          beyond the RHEL5 defaults. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

          This section introduces other uses of SELinux which may be
          possible, and provides links to some outside resources about their use. Detailed
          description of how to implement these steps is beyond the scope of this guide.</xccdf:description>

            SELinux booleans are used to enable or disable segments of
            policy to comply with site policy. Booleans may apply to the entire system or to an
            individual daemon. For instance, the boolean allow execstack, if enabled, allows
            programs to make part of their stack memory region executable. This would apply to all
            programs on the system. The boolean ftp home dir allows ftpd processes to access user
            home directories, and applies only to daemons which implement FTP. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            lists the values of all SELinux booleans on the system. Section 2.4.5
            discussed loosening boolean values in order to debug functionality problems which occur
            under more restrictive defaults. It is also useful to examine and strengthen the boolean
            settings, to disable functionality which is not required by legitimate programs on your
            system, but which might be symptomatic of an attack. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            See the manpages booleans(8),
            getsebool(8), and setsebool(8) for general information about booleans. There are also
            manual pages for several subsystems which discuss the use of SELinux with those systems.
            Examples include ftpd selinux(8), httpd selinux(8), and nfs selinux(8). Another good
            reference is the html documentation distributed with the selinux-policy RPM. This

            Using a stronger policy can greatly enhance security, but will
            generally require customization to be compatible with the particular system's purpose,
            and this may be costly or time consuming. Under the targeted policy, interactive
            processes are given the type unconfined t, so interactive users are not constrained by
            SELinux even if they attempt to take strange or malicious actions. The first alternative
            policy available with RHEL5's SELinux distribution, called strict, extends the
            protections offered by the default policy from daemons and system processes to all
            processes. To use the strict policy, first ensure that the policy module is installed: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

          Wireless networking (sometimes referred to as 802.11 or Wi-Fi)
          presents a serious security risk to sensitive or classified systems and networks. Wireless
          networking hardware is much more likely to be included in laptop or portable systems than
          desktops or servers. See Section 3.3.14 for information on Bluetooth wireless support.
          Bluetooth serves a different purpose and possesses a much shorter range, but it still
          presents serious security risks. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          Removal of hardware is the only way to absolutely ensure
          that the wireless capability remains disabled. If it is completely impractical to remove
          the wireless hardware, and site policy still allows the device to enter sensitive spaces,
          every effort to disable the capability via software should be made. In general,
          acquisition policy should include provisions to prevent the purchase of equipment that
          will be used in sensitive spaces and includes wireless capabilities.</xccdf:description>

                      <xccdf:description xml:lang="en">
            Identifying the wireless hardware is the first step in removing
            it. The system's hardware manual should contain information on its wireless
            capabilities. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Wireless hardware included with a laptop typically takes the form of a
            mini-PCI card or PC card. Other forms include devices which plug into USB or Ethernet
            ports, but these should be readily apparent and easy to remove from the base system. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            A PC Card (originally called a PCMCIA card) is designed to be easy to remove, though it
            may be hidden when inserted into the system. Frequently, there will be one or more
            buttons near the card slot that, when pressed, eject the card from the system. If no
            card is ejected, the slot is empty. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            A mini-PCI card is approximately credit-card sized
            and typically accessible via a removable panel on the underside of the laptop. Removing
            the panel may require simple tools. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            In addition to manually inspecting the hardware, it
            is also possible to query the system for its installed hardware devices. The commands
            /sbin/lspci and /sbin/lsusb will show a list of all recognized devices on their
            respective buses, and this may indicate the presence of a wireless device.</xccdf:description>

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              First, identify the interfaces available with the command: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              Additionally,the following command may also be used to
              determine whether wireless support ('extensions') is included for a particular
              interface, though this may not always be a clear indicator: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              After
              identifying any wireless interfaces (which may have names like wlan0, ath0, wifi0, or
              eth0), deactivate the interface with the command: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              These changes

            Because the IPv6 networking code is relatively new and complex,
            it is particularly important that it be disabled unless needed. Despite configuration
            that suggests support for IPv6 has been disabled, link-local IPv6 address
            autoconfiguration occurs even when only an IPv4 address is assigned. The only way to
            effectively prevent execution of the IPv6 networking stack is to prevent the kernel from
            loading the IPv6 kernel module.</xccdf:description>

              Automatically-generated IPv6 addresses are based on the underlying hardware (e.g.
              Ethernet) address, and so it becomes possible to track a piece of hardware over its
              lifetime using its traffic. If it is important for a system's IP address to not
              trivially reveal its hardware address, this setting should be applied.</xccdf:description>

                    <xccdf:description xml:lang="en">
          TCP Wrapper is a library which provides simple access control and
          standardized logging for supported applications which accept connections over a network.
          Historically, TCP Wrapper was used to support inetd services. Now that inetd is deprecated
          (see Section 3.2.1), TCP Wrapper supports only services which were built to make use of
          the libwrap library. To determine whether a given executable daemon /path/to/daemon
          supports TCP Wrapper, check the documentation, or run: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:code xmlns:xhtml="http://www.w3.org/1999/xhtml">$ ldd /path/to/daemon | grep libwrap.so <xhtml:br/></xhtml:code>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          If this command returns any output, then the daemon probably supports TCP Wrapper. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          An alternative to TCP Wrapper support is packet filtering using iptables. Note
          that iptables works at the network level, while TCP Wrapper works at the application
          level. This means that iptables filtering is more efficient and more resistant to flaws in
          the software being protected, but TCP Wrapper provides support for logging, banners, and
          other application-level tricks which iptables cannot provide.</xccdf:description>

                /etc/hosts.allow is searched for a rule matching the connection. If one is found, the
                connection is allowed. </xhtml:li><xhtml:li>Otherwise, the file /etc/hosts.deny is searched for a rule
                matching the connection. If one is found, the connection is rejected. </xhtml:li><xhtml:li>If no matching
                rules are found in either file, then the connection is allowed. By default, TCP Wrapper

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            In the simplest case, each rule in /etc/hosts.allow and /etc/hosts.deny takes the form: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            daemon : client <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            where daemon is the
            name of the server process for which the connection is destined, and client is the
            partial or full hostname or IP address of the client. It is valid for daemon and client
            to contain one item, a comma-separated list of items, or a special keyword like ALL,
            which matches any service or client. (See the hosts access(5) manpage for a list of
            other keywords.) <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Note: Partial hostnames start at the root domain and are delimited by
            the . character. So the client machine host03.dev.example.com, with IP address 10.7.2.3,
            could be matched by any of the specifications: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

          A host-based firewall called Netfilter is included as part of the
          Linux kernel distributed with the system. It is activated by default. This firewall is
          controlled by the program iptables, and the entire capability is frequently referred to by
          this name. An analogous program called ip6tables handles filtering for IPv6. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          Unlike TCP
          Wrappers, which depends on the network server program to support and respect the rules
          written, Netfilter filtering occurs at the kernel level, before a program can even process
          the data from the network packet. As such, any program on the system is affected by the
          rules written. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            The ip6tables default rules are similar, with
            its rules 2 and 10 reflecting protocol naming and addressing differences. Instead of
            rule 8, however, ip6tables includes two rules that accept all incoming udp and tcp
            packets with a particular destination port range. This is because the current Netfilter
            implementation for IPv6 lacks reliable connection-tracking functionality.</xccdf:description>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The default ruleset is divided into four sections, each of which
            is called a chain: INPUT, FORWARD, OUTPUT, and RH-Firewall-1-INPUT. INPUT, OUTPUT, and
            FORWARD are built-in chains. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:ul xmlns:xhtml="http://www.w3.org/1999/xhtml"><xhtml:li>The INPUT chain is activated on packets destined for
                (i.e., addressed to) the system. </xhtml:li><xhtml:li>The OUTPUT chain is activated on packets which are
                originating from the system. </xhtml:li><xhtml:li>The FORWARD chain is activated for packets that the
                system will process and send through another interface, if so configured. </xhtml:li><xhtml:li>The
                RH-Firewall-1-INPUT chain is a custom (or user-defined) chain, which is used by the
                INPUT and FORWARD chains. </xhtml:li></xhtml:ul>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            A packet starts at the first rule in the appropriate chain and
            proceeds until it matches a rule. If a match occurs, then control will jump to the
            specified target. The default ruleset uses the built-in targets ACCEPT and REJECT, and
            also the user-defined target/chain RH-Firewall-1-INPUT. Jumping to the target ACCEPT
            means to allow the packet through, while REJECT means to drop the packet and send an
            error message to the sending host. A related target called DROP means to drop the packet
            on the floor without even sending an error message. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The default policy for all of the
            built-in chains (shown after their names in the rule output above) is set to ACCEPT.
            This means that if no rules in the chain match the packets, they are allowed through.
            Because no rules at all are written for the OUTPUT chain, this means that iptables does
            not stop any packets originating from the system. The INPUT and FORWARD chains jump to
            the user-defined target RH-Firewall-1-INPUT for all packets. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            RH-Firewall-1-INPUT tries
            to match, in order, the following rules for both iptables and ip6tables: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:ul xmlns:xhtml="http://www.w3.org/1999/xhtml"><xhtml:li>Rule 1
                appears to accept all packets. However, this appears true only because the rules are not
                presented in verbose mode. Executing the command <xhtml:br/>
                <xhtml:br/>
                <xhtml:code># iptables -vnL --line-numbers <xhtml:br/></xhtml:code>
                <xhtml:br/>
                reveals
                that this rule applies only to the loopback (lo) interface (see column in), while all
                other rules apply to all interfaces. Thus, packets not coming from the loopback
                interface do not match and proceed to the next rule. </xhtml:li><xhtml:li>Rule 2 explicitly allows all icmp
                packet types; iptables uses the code 255 to mean all icmp types. </xhtml:li><xhtml:li>Rule 3 explicitly
                allows all esp packets; these are packets which contain IPsec ESP headers.</xhtml:li><xhtml:li>Rule 4
                explicitly allows all ah packets; these are packets which contain an IPsec
                authentication header SPI. </xhtml:li><xhtml:li>Rule 5 allows inbound communication on udp port 5353
                (mDNS), which the avahi daemon uses. </xhtml:li><xhtml:li>Rules 6 and 7 allows inbound communication on
                both tcp and udp port 631, which the cups daemon uses. </xhtml:li><xhtml:li>Rule 8, in the iptables rules,
                allows inbound packets that are part of a session initiated by the system. In ip6tables,
                rules 8 and 9 allow any inbound packets with a destination port address between 32768
                and 61000. </xhtml:li><xhtml:li>Rule 9 (10, for ip6tables) allows inbound connections in tcp port 22, which
                is the SSH protocol. </xhtml:li><xhtml:li>Rule 10 (11, for ip6tables) rejects all other packets and sends
                an error message to the sender. Because this is the last rule and matches any packet, it
                effectively prevents any packet from reaching the chain's default ACCEPT target.
                Preventing the acceptance of any packet that is not explicitly allowed is proper design
                for a firewall.</xhtml:li></xhtml:ul></xccdf:description>

            The default rules can be strengthened. The system scripts that
            activate the firewall rules expect them to be defined in the configuration files
            iptables and ip6tables in the directory /etc/sysconfig. Many of the lines in these files
            are similar to the command line arguments that would be provided to the programs
            /sbin/iptables or /sbin/ip6tables – but some are quite different. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The following recommendations describe how to strengthen the default
            ruleset configuration file. An alternative to editing this configuration file is to
            create a shell script that makes calls to the iptables program to load in rules, and
            then invokes service iptables save to write those loaded rules to
            /etc/sysconfig/iptables. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The following alterations can be made directly to
            /etc/sysconfig/iptables and /etc/sysconfig/ip6tables. Instructions apply to both unless
            otherwise noted. Language and address conventions for regular iptables are used
            throughout this section; configuration for ip6tables will be either analogous or

              Because IPv6 depends so
              heavily on ICMPv6, it is preferable to deny the ICMPv6 packets you know you don't need
              (e.g. ping requests) in /etc/sysconfig/ip6tables, while letting everything else
              through: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              -A RH-Firewall-1-INPUT -p icmpv6 --icmpv6-type echo-request -j DROP <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              If you
              are going to statically configure the machine's address, it should ignore Router
              Advertisements which could add another IPv6 address to the interface or alter
              important network settings: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              Restricting other ICMPv6 message types in
              /etc/sysconfig/ip6tables is not recommended because the operation of IPv6 depends
              heavily on ICMPv6. Thus, more care must be taken when blocking ICMPv6 types.</xccdf:description>

                protocols such as ftp and telnet, or even disrupt spyware. However, it would still not
                prevent a sophisticated user or program from using a proxy to circumvent the intended

                recent match allows the firewall to deny additional connections from any host within a
                given period of time (e.g. more than 3 –state NEW connections on port 22 within a minute

                    <xccdf:description xml:lang="en">
          The Secure Sockets Layer (SSL) protocol provides encrypted and
          authenticated network communications, and many network services include support for it.
          Using SSL is recommended, especially to avoid any plaintext transmission of sensitive
          data, even over a local network. The SSL implementation included with the system is called
          OpenSSL. Recent implementations of SSL may also be referred to as Transport Layer Security
          (TLS). <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          SSL uses public key cryptography to provide authentication and encryption. Public
          key cryptography involves two keys, one called the public key and the other called the
          private key. These keys are mathematically related such that data encrypted with one key
          can only be decrypted by the other, and vice versa. As their names suggest, public keys
          can be distributed to anyone while a private key must remain known only to its owner. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          SSL uses certificates, which are files that hold cryptographic data: a public key, and a
          signature of that public key. In SSL authentication, a server presents a client with its
          certificate as a means of demonstrating that it is who it claims it is. If everything goes
          correctly, the client can verify the server's certificate by determining that the
          signature inside the certificate could only have been generated by a third party whom the
          client trusts. This third party is called a Certificate Authority (CA). Each client system
          should also have certificates from trusted CAs, and the client uses these CA certificates
          to verify the authenticity of the server's certificate. After authenticating a server
          using its certificate and a CA certificate, SSL provides encryption by using the server
          certificate to securely negotiate a shared secret key. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          If your server must communicate
          using SSL with systems that might not be able to securely accept a new CA certificate
          prior to any SSL communication, then paying an established CA (whose certificates your
          clients already have) to sign your server certificates is recommended. The steps for doing
          this vary by vendor. Once the signed certificates have been obtained, configuration of the
          services is the same whether they were purchased from a vendor or signed by your own CA.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          For setting up an internal network and encrypting local traffic, creating your own CA to
          sign SSL certificates can be appropriate. The major steps in this process are: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            The following instructions apply to OpenSSL since it is
            included with the system, but creating a CA is possible with any standards-compliant SSL
            toolkit. The security of certificates depends on the security of the CA that signed
            them, so performing these steps on a secure machine is critical. The system used as a CA
            should be physically secure and not connected to any network. It should receive any
            certificate signing requests (CSRs) via removable media and output certificates onto
            removable media. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            settings in this file can be changed to suit your needs and allow easier selection of
            default settings, particularly in the [req distinguished name] section. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

                /etc/pki/CA (by default), which contains files necessary for the operation of a

            When the CA later signs a server certificate using its private
            key, it means that it is vouching for the authenticity of that server. A client can then
            use the CA's certificate (which contains its public key) to verify the authenticity of
            the server certificate. To accomplish this, it is necessary to distribute the CA
            certificate to any clients as covered in Section 2.5.6.3.</xccdf:description>

        Successful local or network attacks on systems do not necessarily
        leave clear evidence of what happened. It is necessary to build a configuration in advance
        that collects this evidence, both in order to determine that something anomalous has
        occurred, and in order to respond appropriately. In addition, a well-configured logging and
        audit infrastructure will show evidence of any misconfiguration which might leave the system
        vulnerable to attack. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        Logging and auditing take different approaches to collecting data. A
        logging infrastructure provides a framework for individual programs running on the system to
        report whatever events are considered interesting: the sshd program may report each
        successful or failed login attempt, while the sendmail program may report each time it sends
        an e-mail on behalf of a local or remote user. An auditing infrastructure, on the other
        hand, reports each instance of certain low-level events, such as entry to the setuid system
        call, regardless of which program caused the event to occur. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        Auditing has the advantage of
        being more comprehensive, but the disadvantage of reporting a large amount of information,
        most of which is uninteresting. Logging (particularly using a standard framework like
        syslog) has the advantage of being compatible with a wide variety of client applications,
        and of reporting only information considered important by each application, but the
        disadvantage that the information reported is not consistent between applications. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        A robust
        infrastructure will perform both logging and auditing, and will use configurable automated
        methods of summarizing the reported data, so that system administrators can remove or
        compress reports of events known to be uninteresting in favor of alert monitoring for events
        known to be interesting. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

        This section discusses how to configure logging, log monitoring,
        and auditing, using tools included with RHEL5. It is recommended that syslog be used for
        logging, with logwatch providing summarization, and that auditd be used for auditing, with
        aureport providing summarization.</xccdf:description>

            When a message is sent to syslog for logging, it is sent with a facility name (such as
            mail, auth, or local2), and a priority (such as debug, notice, or emerg). Each line of
            syslog's configuration file is a directive which specifies a set of facility/priority
            pairs, and then gives a filename or host to which log messages of matching types should
            be sent. In order for a message to match a type, the facility must match, and the
            priority must be the priority named in the rule or any higher priority. (See
            syslog.conf(5) for an ordered list of priorities.) <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Older versions of syslog mandated a
            very restrictive format for the syslog.conf file. However, the version of syslog shipped
            with RHEL5 allows any sort of whitespace (spaces or tabs, not just tabs) to separate the
            selection criteria from the message disposition, and allows the use of facility.* as a
            wildcard matching a given facility at any priority. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The default RHEL5 syslog
            configuration stores the facilities authpriv, cron, and mail in named logs. This guide
            describes the implementation of the following configuration, but any configuration which
            stores the important facilities and is usable by the administrators will suffice:<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:ul xmlns:xhtml="http://www.w3.org/1999/xhtml"><xhtml:li>Store each of the facilities kern, daemon, and syslog in its own log, so that it will be
                easy to access information about messages from those facilities. </xhtml:li><xhtml:li>Restrict the
                information stored in /var/log/messages to only the facilities auth and user, and store
                all messages from those facilities. Messages can easily become cluttered otherwise. </xhtml:li><xhtml:li>Store information about all facilities which should not be in use at this site in a file
                called /var/log/ unused.log. If any messages are logged to this file at some future
                point, this may be an indication that an unknown service is running, and should be
                investigated. In addition, if news and uucp are not in use at this site, remove the
                directive from the default syslog.conf which stores those facilities. </xhtml:li></xhtml:ul><xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Making use of the
            local facilities is also recommended. Specific configuration is beyond the scope of this
            guide, but applications such as SSH can easily be configured to log to a local facility
            which is not being used for anything else. If this is done, reconfigure /etc/syslog.conf
            to store this facility in an appropriate named log or in /var/log/messages, rather than
            in /var/log/unused.log.</xccdf:description>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:code xmlns:xhtml="http://www.w3.org/1999/xhtml"># touch LOGFILE<xhtml:br/> 
            # chown root:root LOGFILE <xhtml:br/>
            # chmod 0600 LOGFILE <xhtml:br/></xhtml:code>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Syslog will
            refuse to log to a file which does not exist. All messages intended for that file will
            be silently discarded, so it is important to verify that all log files exist. Some logs
            may contain sensitive information, so it is better to restrict permissions so that only
            administrative users can read or write logfiles.</xccdf:description>

            If system logs are to be useful in detecting malicious activities, it is necessary to
            send logs to a remote server. An intruder who has compromised the root account on a
            machine may delete the log entries which indicate that the system was attacked before
            they are seen by an administrator. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            However, it is recommended that logs be stored on the
            local host in addition to being sent to the loghost, because syslog uses the UDP
            protocol to send messages over a network. UDP does not guarantee reliable delivery, and
            moderately busy sites will lose log messages occasionally, especially in periods of high
            traffic which may be the result of an attack. In addition, remote syslog messages are
            not authenticated in any way, so it is easy for an attacker to introduce spurious
            messages to the central log server. Also, some problems cause loss of network
            connectivity, which will prevent the sending of messages to the central server. For all
            of these reasons, it is better to store log messages both centrally and on each host, so
            that they can be correlated if necessary.</xccdf:description>

            By default, RHEL5's syslog does not listen over
            the network for log messages. The -r flag enables syslogd to listen over a network, and
            should be used only if necessary. The -s example.com flag strips the domain name
            example.com from each sending machine's hostname before logging messages from that host,
            to reduce the amount of redundant information placed in log files. See the syslogd(8)

            All logs in use on a system must be rotated regularly, or the log
            files will consume disk space over time, eventually interfering with system operation.
            The file /etc/logrotate.d/syslog is the configuration file used by the logrotate program
            to maintain all log files written by syslog. By default, it rotates logs weekly and
            stores four archival copies of each log. These settings can be modified by editing
            /etc/logrotate.conf, but the defaults are sufficient for purposes of this guide. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            The system includes an extensible program called Logwatch for
            reporting on unusual items in syslog. Logwatch is valuable because it provides a parser
            for the syslog entry format and a number of signatures for types of lines which are
            considered to be mundane or noteworthy. Logwatch has a number of downsides: the
            signatures can be inaccurate and are not always categorized consistently, and you must
            be able to program in Perl in order to customize the signature database. However, it is
            recommended that all Linux sites which do not have time to deploy a third-party log
            monitoring application run Logwatch in its default configuration. This provides some
            useful information about system activity in exchange for very little administrator
            effort. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            This guide recommends that Logwatch be run only on the central logserver, if
            your site has one, in order to focus administrator attention by sending all daily logs
            in a single e-mail.</xccdf:description>

              On a central logserver, you want
              Logwatch to summarize all syslog entries, including those which did not originate on
              the logserver itself. The HostLimit setting tells Logwatch to report on all hosts, not
              just the one on which it is running. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              If SplitHosts is set, Logwatch will separate
              entries by hostname. This makes the report longer but significantly more usable. If it
              is not set, then Logwatch will not report which host generated a given log entry, and
              that information is almost always necessary. If MultiEmail is set, then each host's
              information will be sent in a separate e-mail message. This is a matter of preference.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              The Service directive -zz-disk space tells Logwatch not to run the zz-disk space
              report, which reports on free disk space. Since all log monitoring is being done on
              the central logserver, the disk space listing will always be that of the logserver,
              regardless of which host is being monitored. This is confusing, so disable that
              service. Note that this does mean that Logwatch will not monitor disk usage
              information. Many workarounds are possible, such as running df on each host daily via
              cron and sending the output to syslog so that it will be reported to the logserver.</xccdf:description>

          The audit service is the current Linux recommendation for
          kernel-level auditing. By default, the service audits about SELinux AVC denials and
          certain types of security-relevant events such as system logins, account modifications,
          and authentication events performed by programs such as sudo. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

          Under its default
          configuration, auditd has modest disk space requirements, and should not noticeably impact
          system performance. The audit service, in its default configuration, is strongly
          recommended for all sites, regardless of whether they are running SELinux. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            By default, auditd logs only SELinux denials, which are
            helpful for debugging SELinux and discovering intrusion attempts, and certain types of

            Data is stored in /var/log/audit/audit.log. By default,
            auditd rotates 4 logs by size (5MB), retaining a maximum of 20MB of data in total, and
            refuses to write entries when the disk is too full. This minimizes the risk of audit
            data filling its partition and impacting other services. However, it is possible to lose

                admin_space_left_action = halt<xhtml:br/></xhtml:li></xhtml:ul>
            The default action to take when the logs reach their maximum size is to rotate the log ﬁles, discarding the
            oldest one. If it is more important to retain all possible auditing information, even if that opens the possibility
            of running out of space and taking the action deﬁned by admin space left action, add or correct the line:<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            By default, auditd retains 4 log ﬁles of size 5Mb apiece. For a busy system or a system which is thoroughly
            auditing system activity, this is likely to be insuﬃcient.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The log ﬁle size needed will depend heavily on what types of events are being audited. First conﬁgure auditing
            to log all the events of interest. Then monitor the log size manually for awhile to determine what ﬁle size will
            allow you to keep the required data for the correct time period.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Using a dedicated partition for /var/log/audit prevents the auditd logs from disrupting system functionality if
            they ﬁll, and, more importantly, prevents other activity in /var from ﬁlling the partition and stopping the audit
            trail. (The audit logs are size-limited and therefore unlikely to grow without bound unless conﬁgured to do so.)
            Some machines may have requirements that no actions occur which cannot be audited. If this is the case, then
            auditd can be conﬁgured to halt the machine if it runs out of space.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Note: Since older logs are rotated, conﬁguring auditd this way does not prevent older logs from being rotated
            away before they can be viewed.

            Familiarize yourself with the aureport(8) man page, then design a short series of audit reporting commands
            suitable for exploring the audit logs on a daily (or more frequent) basis. These commands can be added as a cron
            job by placing an appropriately named ﬁle in /etc/cron.daily. See the next section for information on how to

        This section discusses a number of network-visible services which
        have historically caused problems for system security, and for which disabling or severely
        limiting the service has been the best available guidance for some time. As a result of this
        consensus, these services are not installed as part of RHEL5 by default. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        Organizations which
        are running these services should prioritize switching to more secure services which provide
        the needed functionality. If it is absolutely necessary to run one of these services for
        legacy reasons, care should be taken to restrict the service as much as possible, for
        instance by configuring host firewall software (see Section 2.5.5) to restrict access to the
        vulnerable service to only those remote hosts which have a known need to use it.</xccdf:description>

          Is there an operational need to run the deprecated inetd or

          Beginning with Red Hat Enterprise Linux 5, the xinetd service is no
          longer installed by default. This change represents increased awareness that the dedicated
          network listener model does not improve security or reliability of services, and that
          restriction of network listeners is better handled using a granular model such as SELinux
          than using xinetd's limited security options.</xccdf:description>

            Zeroconf networking allows the system to assign itself an IP
            address and engage in IP communication without a statically-assigned address or even a
            DHCP server. Automatic address assignment via Zeroconf (or DHCP) is not recommended. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            To disable Zeroconf automatic route assignment in the 169.245.0.0 subnet, add or correct
            the following line in /etc/sysconfig/network: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            Zeroconf addresses are in
            the network 169.254.0.0. The networking scripts add entries to the system's routing
            table for these addresses. Zeroconf address assignment commonly occurs when the system
            is configured to use DHCP but fails to receive an address assignment from the DHCP
            server.</xccdf:description>

              of being mounted will be labeled this way) and sets the corresponding volume.ignore

          Bluetooth provides a way to transfer information between devices
          such as mobile phones, laptops, PCs, printers, digital cameras, and video game consoles
          over a short-range wireless link. Any wireless communication presents a serious security
          risk to sensitive or classified systems. Section 2.5.2 contains information on the related
          topic of wireless networking. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          Removal of hardware is the only way to ensure that the
          Bluetooth wireless capability remains disabled. If it is completely impractical to remove
          the Bluetooth hardware module, and site policy still allows the device to enter sensitive
          spaces, every effort to disable the capability via software should be made. In general,
          acquisition policy should include provisions to prevent the purchase of equipment that
          will be used in sensitive spaces and includes Bluetooth capabilities.</xccdf:description>

          Cron and anacron make use of a
          number of configuration files and directories. The system crontabs need only be edited by
          root, and user crontabs are edited using the setuid root crontab command. If unprivileged
          users can modify system cron configuration files, they may be able to gain elevated
          privileges, so all unnecessary access to these files should be disabled.</xccdf:description>

            After this interval has passed, the idle user will be automatically logged out. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Find and edit the following lines in /etc/ssh/sshd config as follows: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            The timeout interval is given in seconds. 
            To have a timeout of 5 minutes, set interval to 300. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            If a shorter timeout has already been set for
            the login shell, as in Section 2.3.5.5, that value will preempt any SSH setting made
            here. Keep in mind that some processes may stop SSH from correctly detecting that the

            Avahi can be set to ignore IP packets unless their TTL field is
            255. To make Avahi ignore packets unless the TTL field is 255, edit
            /etc/avahi/avahi-daemon.conf and ensure the following line appears in the [server]
            section: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            This helps to ensure that only mDNS responses from the
            local network are processed, because the TTL field in a packet is decremented from its
            initial value of 255 whenever it is routed from one network to another. Although a
            properly-configured router or firewall should not allow mDNS packets into the local
            network at all, this option provides another check to ensure they are not trusted.</xccdf:description>

            These options
            should be used even if publishing is disabled entirely via disable-publishing, since
            that option prevents publishing attempts from succeeding, while these options prevent
            the attempts from being made in the first place. Using both approaches is recommended

        The Common Unix Printing System (CUPS) service provides both local
        and network printing support. A system running the CUPS service can accept print jobs from
        other systems, process them, and send them to the appropriate printer. It also provides an
        interface for remote administration through a web browser. The CUPS service is installed and
        activated by default. The project homepage and more detailed documentation are available at
        http://www.cups.org. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

          act as a print server. Whenever possible, the printer sharing and print server

              It is possible to disable outgoing printer list broadcasts
              without affecting incoming broadcasts from other machines. To do so, open the CUPS
              configuration file, located at /etc/cups/cupsd.conf. Look for the line that begins
              with BrowseAddress and remove it. The line will look like the following: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              BrowseAddress @LOCAL <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              If the intent is not to block printer sharing, but to limit it to a particular
              set of machines, you can limit the UDP printer broadcasts to trusted network
              addresses. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              BrowseAddress ip-address :631 <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              Likewise, to ignore incoming UDP printer list
              broadcasts, or to limit the set of machines to listen to, use the BrowseAllow and
              BrowseDeny directives. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              BrowseDeny all <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              BrowseAllow ip-address <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              This combination will
              deny incoming broadcasts from any machine except those that are explicitly allowed
              with BrowseAllow. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              By default, when printer sharing is enabled, CUPS will broadcast to
              every network that its host machine is connected to through all available network
              interfaces on port 631. It will also listen to incoming broadcasts from other machines
              on the network. Either list one BrowseAddress line for each client machine and one
              BrowseAllow line for each print server or use one of the supported shorthand notations

            To prevent remote users from potentially
            connecting to and using locally configured printers, disable the CUPS print server
            sharing capabilities. To do so, limit how the server will listen for print jobs by
            removing the more generic port directive from /etc/cups/cupsd.conf: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Port 631 <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            and replacing it with the Listen directive: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Listen localhost:631 <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            This will prevent remote
            users from printing to locally configured printers while still allowing local users on
            the machine to print normally. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            By default, locally configured printers will not be
            shared over the network, but if this functionality has somehow been enabled, these
            recommendations will disable it again. Be sure to disable outgoing printer list
            broadcasts, or remote users will still be able to see the locally configured printers,
            even if they cannot actually print to them. To limit print serving to a particular set
            of users, use the Policy directive.</xccdf:description>

            By default, access to the CUPS web administration interface is
            limited to the local machine. It is recommended that this not be changed, especially
            since the authentication mechanisms that CUPS provides are limited in their
            effectiveness. If it is absolutely necessary to allow remote users to administer locally
            installed printers, be sure to limit that access as much as possible by taking advantage
            of the Location and Policy directive blocks. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            For example, to enable
            remote access for ip-address for user username, modify each of the Location and Policy
            directive blocks as follows: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            &lt;Location /&gt; <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            AuthType Basic <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Require user username <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            As with the
            BrowseAllow directive, use one Allow directive for each machine that needs access or use
            one of the available CUPS directive definition shortcuts to enable access from a class
            of machines at once. The Require user directive can take a list of individual users, a
            group of users (prefixed with @), or the shorthand valid-user. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Host-based authentication has known limitations,
            especially since IP addresses are easy to spoof. Requiring users to authenticate
            themselves can alleviate this problem, but it cannot eliminate it. Do not use the root
            account to manage and administer printers. Create a separate account for this purpose
            and limit access to valid users with Require valid-user or Require user printeradmin .

                  <xccdf:description xml:lang="en">
        The Dynamic Host Configuration Protocol (DHCP) allows systems to
        request and obtain an IP address and many other parameters from a server. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        In general, sites
        use DHCP either to allow a large pool of mobile or unknown machines to share a limited
        number of IP addresses, or to standardize installations by avoiding static, individual IP
        address configuration on hosts. It is recommended that sites avoid DHCP as much as possible.
        Since DHCP authentication is not well-supported, DHCP clients are open to attacks from rogue
        DHCP servers. Such servers can give clients incorrect information (e.g. malicious DNS server
        addresses) which could lead to their compromise. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        If a machine must act as a DHCP client or
        server, configure it defensively using the guidance in this section. This guide recommends
        configuring networking on clients by manually editing the appropriate files under
        /etc/sysconfig. It is also possible to use the graphical front-end programs
        system-config-network and system-config-network-tui, but these programs rewrite
        configuration files from scratch based on their defaults – destroying any manual changes –
        and should therefore be used with caution.</xccdf:description>

            Create the file /etc/dhclient.conf, and add an appropriate

            For example, suppose the

            By default, the DHCP
            client program, dhclient, requests and applies ten configuration options (in addition to
            the IP address) from the DHCP server: subnet-mask, broadcast-address, time-offset,
            routers, domain-name, domain-name-servers, host-name, nis-domain, nis-servers, and

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Many of the options requested and applied by dhclient may be the same for
            every system on a network. It is recommended that almost all configuration options be
            assigned statically, and only options which must vary on a host-by-host basis be
            assigned via DHCP. This limits the damage which can be done by a rogue DHCP server. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            If
            appropriate for your site, it is also possible to supersede the host-name directive in
            /etc/dhclient.conf, establishing a static hostname for the machine. However, dhclient
            does not use the host name option provided by the DHCP server (instead using the value
            provided by a reverse DNS lookup). <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Note: In this example, the options nis-servers and
            nis-domain are set to empty strings, on the assumption that the deprecated NIS protocol
            is not in use. (See Section 3.2.4.) It is necessary to supersede settings for unused
            services so that they cannot be set by a hostile DHCP server. If an option is set to an
            empty string, dhclient will typically not attempt to configure the service.</xccdf:description>

                      <xccdf:description xml:lang="en">
            To prevent the DHCP server from receiving DNS information from
            clients, edit /etc/dhcpd.conf, and add or correct the following global option:<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The Dynamic DNS protocol is used to remotely update the data
            served by a DNS server. DHCP servers can use Dynamic DNS to publish information about
            their clients. This setup carries security risks, and its use is not recommended. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            If Dynamic DNS must be used despite the risks it poses, it is critical that Dynamic DNS
            transactions be protected using TSIG or some other cryptographic authentication
            mechanism. See Section 3.14 for more information about DNS servers, including further
            information about TSIG and Dynamic DNS. Also see dhcpd.conf(5) for more information
            about protecting the DHCP server from passing along malicious DNS data from its clients.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Note: The ddns-update-style option controls only whether the DHCP server will attempt to
            act as a Dynamic DNS client. As long as the DNS server itself is correctly configured to
            reject DDNS attempts, an incorrect ddns-update-style setting on the client is harmless
            (but should be fixed as a best practice).</xccdf:description>

            necessary for proper network functionality, but are also usually static across machines

                  <xccdf:description xml:lang="en">
        The Network Time Protocol is used to manage the system clock over a
        network. Computer clocks are not very accurate, so time will drift unpredictably on
        unmanaged systems. Central time protocols can be used both to ensure that time is consistent
        among a network of machines, and that their time is consistent with the outside world. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        Local time synchronization is recommended for all networks. If every machine on your network
        reliably reports the same time as every other machine, then it is much easier to correlate
        log messages in case of an attack. In addition, a number of cryptographic protocols (such as
        Kerberos) use timestamps to prevent certain types of attacks. If your network does not have
        synchronized time, these protocols may be unreliable or even unusable. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        Depending on the specifics of the network, global time accuracy may be just as important as 
        local synchronization, or not very important at all. If your network is connected to the 
        Internet, it is recommended that you make use of a public timeserver, since globally 
        accurate timestamps may be necessary if you need to investigate or respond to an attack 
        which originated outside of your network. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
        Whether or not you use an outside timeserver, configure
        the network to have a small number of machines operating as NTP servers, and the remainder
        obtaining time information from those internal servers.</xccdf:description>

          The Network Time Protocol (RFC 1305) is designed to synchronize
          time with a very high degree of accuracy even on an unreliable network. NTP is therefore a
          complex protocol. The Simple Network Time Protocol (RFC 4330) implements a subset of NTP
          which is intended to be good enough to meet the time requirements of most networks. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          The primary implementation of NTP comes from ntp.org, and is shipped with RHEL5 as the ntp
          RPM. An alternative is OpenNTPD, which is an implementation of SNTP, and which can be
          obtained as source code from http://www.openntpd.org. OpenNTPD may be simpler to configure
          than the reference NTP implementation, at the cost of the need to install and maintain
          third-party software. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          This guide does not recommend the use of a particular NTP/SNTP
          software package, but does recommend that some NTP software be selected and installed on
          all machines. The remainder of this section describes how to securely configure NTP
          clients and servers, and discusses both the reference NTP implementation and OpenNTPD.</xccdf:description>

            There are a number of options for conﬁguring clients to work with the reference NTP server. It is possible to run
            ntpd as a service (i.e., continuously) on each host, conﬁguring clients so that the ntp protocol ignores all network
            access. This still introduces an additional network listener on client machines, and is therefore not recommended.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            This guide instead recommends running ntpd periodically via cron. It is also possible to run ntpdate via cron
            with the -u option, but it is being obsoleted in favor of ntpd.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Alternately, even if the server is running the reference NTP implementation, it is possible for clients to access it
            using SNTP. See Section 3.10.3.2 for information about conﬁguring SNTP clients.</xccdf:description>

              If your site
              does not require time data to be accurate, but merely to be synchronized among local
              machines, this step can be omitted, and the NTP server will default to providing time
              data from the local clock. However, it is a good idea to periodically synchronize the
              clock to some source of accurate time, even if it is not appropriate to do so
              automatically. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              The previous step disabled all remote access to this NTP server's state
              data. This NTP server must contact a remote server to obtain accurate data, so NTP's
              configuration must allow that remote data to be used to modify the system clock. The
              restrict line changes the default access permissions for that remote server. The
              server line specifies the remote server as the preferred NTP server for time data. If
              you intend to synchronize to more than one server, specify restrict and server lines
              for each server. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              Note: It would be possible to specify a hostname, rather than an IP
              address, for the server field. However, the restrict setting applies only to network
              blocks of IP addresses, so it is considered more maintainable to use the IP address in
              both fields.</xccdf:description>

          OpenNTPD is an implementation of the SNTP protocol which is
          provided as a simple alternative to the reference NTP server. Advantages of OpenNTPD
          include simplicity of configuration, built-in privilege separation and chroot jailing of
          the NTP protocol code, and a small codebase which lacks many of the management and other
          protocol features used by the reference NTP server. This simplicity comes at the cost of
          degraded time accuracy, but SNTP is probably accurate enough for most sites with typical
          monitoring requirements.</xccdf:description>

          It is recommended that very few machines at any
          site be configured to receive mail over a network. However, it may be necessary for most
          machines at a given site to send e-mail, for instance so that cron jobs can report output
          to an administrator. Sendmail supports a submission-only mode in which mail can be sent
          from the machine to a central site MTA, but the machine cannot receive mail over a
          network. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

          If a Mail Transfer Agent (MTA) is needed, the system default is Sendmail.
          Postfix, a popular alternative written with security in mind, is also available. Postfix
          can be more effectively contained by SELinux as its modular design has resulted in

            The MTA performs two functions: listening over a network for incoming SMTP
            e-mail requests, and sending mail from the local machine. Since outbound mail may be
            delayed due to network outages or other problems, the outbound MTA runs in a queue-only
            mode, in which it periodically attempts to resend any delayed mail. Setting DAEMON=no
            tells sendmail to execute only the queue runner on this machine, and never to receive
            SMTP mail requests.</xccdf:description>

            This suggestion is provided as a
            simple way to migrate away from a configuration in which each machine at a site runs its
            own MTA, to a configuration in which client machines do not run listening daemons. If
            this modification is made to /etc/mail/submit.cf, then, when a local process on a
            machine attempts to send mail, the message will be forwarded to the machine mailserver
            for processing. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Modifying /etc/mail/submit.cf directly is only appropriate if your site
            does not perform any other mailserver customization on clients. If other customization
            is done, use your usual Sendmail change procedure to define the MTA host. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            the MTA on mailserver so that it will relay mail on behalf of this host.</xccdf:description>

          configuration syntax will differ depending on which MTA is in use (see Section 3.11.5 for

                      <xccdf:description xml:lang="en">
            It is often desirable to constrain an attacker's ability to
            consume a mail server's resources simply by sending otherwise valid mail at a high rate,
            whether maliciously or accidentally. Relevant resource limits include con106 CHAPTER 3.
            SERVICES straints on: the number of MTA daemons which may run at one time, the rate at
            which incoming messages may be received, the size and complexity of each message, or the
            amount of mail queue space which must remain free in order for mail to be delivered.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            That last parameter deserves additional explanation. Most MTAs require queue space for
            temporary files in order to process existing messages in their queues. Therefore, if the
            queue filesystem is allowed to fill completely in a denial of service, the MTA will not
            be able to clear its own queue even when the malicious traffic has stopped. This will
            delay recovery from an attack.</xccdf:description>

            in use, and sometimes also its version number. Remote mail senders do not need this
            information in order to send mail, so the banner should be changed to reveal only the
            hostname (which is already known and may be useful) and the word ESMTP, to indicate that
            the modern SMTP protocol variant is supported.</xccdf:description>

                      <xccdf:description xml:lang="en">
            The sending of Unsolicited Bulk E-mail, referred to variously
            as UBE, UCE, or spam, is a major problem on the Internet today. The security
            implications of spam are that it operates as a Denial of Service attack on legitimate
            e-mail use. Strategies for fighting spam receipt at your site are complex and quickly
            evolving, and thus far beyond the scope of this guide. The problem of relaying
            unauthorized e-mail, however, can and should be addressed by any network-connected site.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Most MTAs perform two functions: to accept mail from remote sites on behalf of local
            users, and to allow local users to send mail to remote sites. The former function is
            relatively easy — mail whose recipient address is local can be assumed to be destined
            for a local user. The latter function is more complex. Since it is typically considered
            neither secure nor desirable for users to log in to the MTA host itself to send mail,
            the MTA must be able to remotely accept mail addressed to anyone from the user's
            workstation. If the MTA is running very old software or is configured poorly, it can be
            possible for attackers to take advantage of this feature, using your MTA to relay their
            spam from one remote site to another. This is undesirable for many reasons, not least
            that your site will quickly be blacklisted as a spam source, leaving you unable to send
            legitimate e-mail to your correspondents. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The simplest solution described in this guide
            is to configure the MTA to relay mail only from the local site's address range, and some
            variant on this is the default for most modern MTAs. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            That solution may be insufficient
            for sites whose users need to send mail from remote machines, for instance while
            travelling, as well as for sites where mail submission must be accepted from network
            ranges which are not considered secure, either because authorized machines are unmanaged
            or because it is possible to connect unauthorized machines to the network. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            If remote or
            mobile hosts are authorized to relay, or if local clients exist in insecure netblocks,
            the SMTP AUTH protocol should be used to require mail senders to authenticate before
            submitting messages. For better protection and to allow support for a wide range of
            authentication mechanisms without sending passwords over a network in clear text, SMTP
            AUTH transactions should be encrypted using SSL. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Another approach is to require mail to
            be submitted on port 587, the designated Message Submission Port. Use of a separate port
            allows the mail relay function to be entirely separated from the mail delivery function.
            This may become a best practice in the future, but description of how to configure the
            Message Submission Port is currently beyond the scope of this guide. See RFC 2476 for
            information about this configuration.</xccdf:description>

            If SMTP AUTH is to be used (see Section 3.11.3.3 for a
            description of possible anti-relaying mechanisms), the use of SSL to protect credentials
            in transit is strongly recommended. There are also configurations for which it may be
            desirable to encrypt all mail in transit from one MTA to another, though such
            configurations are beyond the scope of this guide. In either event, the steps for
            creating and installing an SSL certificate are independent of the MTA in use, and are

              Next,
              generate a certificate signing request (CSR) for the CA to sign, making sure to supply
              your mail server's fully qualified domain name as the Common Name: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              Next, the mail server CSR must be signed to
              create the mail server certificate. You can either send the CSR to an established CA
              or sign it with your CA. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              This step creates a private key,
              mailserverkey.pem, and a public certificate, mailservercert.pem. The mail server will
              use these to prove its identity by demonstrating that it has a certificate which has
              been signed by a CA. Mail clients at your site should be willing to send their mail

              The file /etc/mail/relay-domains must contain only

              relay-domains may send mail through the MTA, and the MTA will also accept inbound mail
              addressed to such hosts. This is a trust relationship — if spammers gain access to
              these machines, your site will effectively become an open relay. It is recommended
              that only machines which are managed by you or by another trusted organization be

              The AUTH MECHANISMS configuration option tells sendmail to allow the
              specified authentication mechanisms to be used during the SMTP dialogue. The two
              listed mechanisms use SASL to test a password provided by the user. Since these
              mechanisms transmit plaintext passwords, they should be protected using TLS as
              described in the next section. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              The TRUST AUTH MECH command tells sendmail that senders
              who successfully authenticate using the specified mechanism may relay mail through
              this MTA even if their addresses are not in relay-domains. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              The file
              /usr/lib/sasl/Sendmail.conf is the Cyrus-SASL configuration file for Sendmail. The
              pwcheck method directive tells SASL how to find passwords. The simplest method,
              described here, is to run a separate authentication daemon, saslauthd, which is able
              to communicate with the system authentication service. On Red Hat, saslauthd uses PAM
              by default, which should work in most cases. If you have a centralized authentication
              system which does not work via PAM, look at the saslauthd(8) manpage to determine how
              to configure saslauthd for your environment.</xccdf:description>

              These options, combined with the previous settings, tell Sendmail to
              protect all SMTP AUTH transactions using TLS. The first four options describe the
              location of the necessary TLS certificate and key files. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              The AUTH OPTIONS parameter
              configures the SMTP AUTH dialogue. The A option is enabled by default, and simply says
              that authentication is allowed if an appropriate mechanism can be found. The p option
              tells Sendmail to protect against passive attacks. The PLAIN and LOGIN authentication
              mechanisms, recommended by this guide for compatibility with PAM, send passwords in
              the clear. (Cleartext password transmissions are vulnerable to passive attack.)
              Therefore, if p is set, the SMTP daemon will not make the AUTH command available until
              after the client has used the STARTTLS command to encrypt the session. If other
              authentication mechanisms were enabled which did not send passwords in the clear, then
              TLS would not necessarily be required.</xccdf:description>

            the number of those which can be occupied by any one remote sender, and

              Postfix can use either the Cyrus library or
              Dovecot as a source for SASL authentication. If this host is running Dovecot for some
              other reason, it is recommended that Dovecot's SASL support be used instead of running
              the Cyrus code as well. See http://www.postfix.org/SASL README.html for instructions

              In Postfix's
              configuration, the directive smtpd sasl auth enable tells smtpd to allow the use of
              the SMTP AUTH command during the SMTP dialogue, and to support that command by getting
              authentication information from SASL. The smtpd recipient restrictions directive is
              changed so that, if the client is not connecting from a trusted address, it is allowed
              to attempt authentication (permit sasl authenticated) in order to relay mail. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              directive tells SASL how to find passwords. The simplest method, described above, is
              to run a separate authentication daemon, saslauthd, which is able to communicate with
              the system authentication system. On RHEL5, saslauthd uses PAM by default, which
              should work in most cases. If you have a centralized authentication system which does
              not work via PAM, look at the saslauthd(8) manpage to find out how to configure
              saslauthd for your environment.</xccdf:description>

            mail only from other trusted sites whose sysadmins can be asked to maintain a copy of

        LDAP is a popular directory service, that is, a standardized way of
        looking up information from a central database. It is relatively simple to configure a RHEL5

          This guide recommends configuring OpenLDAP clients by manually
          editing the appropriate configuration files. RHEL5 provides an automated configuration
          tool called authconfig and a graphical wrapper for authconfig called
          system-config-authentication. However, these tools do not give sufficient flexibility over
          configuration. The authconfig tools do not allow you to specify locations of SSL
          certificate files, which is useful when trying to use SSL cleanly across several
          protocols. They are also overly aggressive in placing services such as netgroups and
          automounter maps under LDAP control, where it is safer to use LDAP only for services to
          which it is relevant in your environment.</xccdf:description>

            Red Hat systems use the file /etc/nsswitch.conf
            to determine the appropriate sources to search for certain kinds of data, such as
            usernames, groups, hostnames, netgroups, or protocols. It is possible to manage many
            other types of data using LDAP, but this guide recommends that only usernames (passwd
            data), passwords (shadow data), and groups (group data) be managed using LDAP. If your
            site uses netgroups, it may be appropriate to manage these via LDAP as well. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            However,
            data which almost never changes, such as the contents of the /etc/services file, is a
            poor choice for central administration, since it introduces risk with little benefit. It
            is recommended that the automounter not be used at all, so LDAP control of automounter
            maps is unlikely to be appropriate. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The file /etc/pam.d/system-auth-ac is used by PAM to
            control access to most authenticated services. The syntax of the PAM configuration file
            is somewhat cryptic. The lines recommended here have the combined effect of using LDAP
            to find authentication data for users who cannot be found in the local /etc/passwd file.
            This means that, for instance, it is still possible to use a local root password. The
            details of options such as broken_shadow, use_authtok, and use_first_pass may be looked
            up in the man pages for the various PAM modules. Their basic effect is to attempt to
            authenticate given a password against both the local /etc/shadow and the central LDAP
            server, without forcing the user to type the password more than once. PAM configuration
            is discussed further in Section 2.3.3.</xccdf:description>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            This
            will output a hashed password string. Edit the file /etc/openldap/slapd.conf, and add or
            correct the line: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            Be sure to select a secure
            password for the LDAP root user, since this user has permission to read and write all
            LDAP data, so a compromise of the LDAP root password will probably enable a full
            compromise of your site. Protect configuration files containing the hashed password the
            same way you would protect other files, such as /etc/shadow, which contain hashed
            authentication data. In addition, be sure to use a reasonably strong hash function, such
            as SHA-1, rather than an insecure scheme such as crypt.</xccdf:description>

                      <xccdf:description xml:lang="en">
            Because LDAP queries and responses, particularly those
            containing authentication information or other sensitive data, must be protected from
            disclosure or modification while in transit over the network, this guide recommends
            using SSL to protect all transactions. In order to do this, it is necessary to have a
            site-wide SSL infrastructure in which a CA certificate is used to verify that other
            certificates, such as that presented by the LDAP server to its clients, are authentic.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Therefore, this procedure involves using the CA system to create a certificate for the
            LDAP server, then installing that certificate on the LDAP server and configuring slapd
            to require its use. See Section 2.5.6 for details about the process of creating SSL
            certificates for use by servers at your site.</xccdf:description>

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              Next, generate a certificate signing request (CSR) for the CA to sign: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              This step creates a private key, ldapserverkey.pem, and a public certificate,
              ldapservercert.pem. The LDAP server will use these to prove its identity by
              demonstrating that it has a certificate which has been signed by the site CA. LDAP
              clients at your site should only be willing to accept authentication data from a
              verified LDAP server.</xccdf:description>

              file belonging to the CA. Note that it would be possible for the key to be protected
              further, so that processes running as ldap could not read it. If this were done, the
              LDAP server process would need to be restarted manually whenever the server rebooted.</xccdf:description>

              credentials (i.e. passwords) in an unencrypted session. It is a good security

              If your site
              implements password expiration in which passwords must be changed every N days (see
              Section 2.3.1.7), then each entry should also have the attribute: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              In general, the LDAP schemas for users use uid to refer to the text username, and
              uidNumber for the numeric UID. This usage may be slightly confusing when compared to
              the standard Unix usage. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              You should not create entries for the root account or for
              system accounts which are unique to individual systems, but only for user accounts
              which are to be shared across machines, and which have authentication information
              (such as a password) associated with them.</xccdf:description>

              LDAP cannot use Posix groups for its own internal
              authentication — it needs to compare the username specified in an authenticated bind
              to some internal groupOfUniqueNames. If you do not specify an LDAP administrators'
              group, then all LDAP management will need to be done using the LDAP root user
              (Manager). For reasons of auditing and error detection, it is recommended that LDAP
              administrators have unique identities. (See Section 2.3.1.3 for similar reasoning
              applied to the use of sudo for privileged system commands.)</xccdf:description>

            OpenLDAP sends its log data to the syslog facility local4 at priority
            debug. By default, RHEL5 does not store this facility at all. The syslog configuration
            suggested here will store any output logged by slapd in the file /var/log/ldap.log, and
            will include that file in the standard log rotation for syslog files. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            By default, LDAP's
            logging is quite verbose. The loglevel parameter is a space-separated list of items to
            be logged. Specifying stats2 will reduce the log output somewhat, but this level will
            still produce some logging every time an LDAP query is made. (This may be appropriate,
            depending on your site's auditing requirements.) In order to capture only slapd startup
            messages, specify loglevel none. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

        with security in mind, and has a number of weaknesses, both in terms of the protocol itself
        and because any NFS installation must expose several daemons, running on both servers and
        clients, to network attack. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

        This section discusses the circumstances under which it is
        possible to disable NFS and its dependencies, and then details steps which should be taken
        to secure, as much as possible, NFS's configuration. This section is relevant to machines
        operating as NFS clients, as well as to those operating as NFS servers.</xccdf:description>

          NFS is a commonly used mechanism for
          sharing data between machines in an organization. However, its use opens many potential

            By design, the RPC
            model does not require particular services to listen on fixed ports, but instead uses a
            daemon, portmap, to tell prospective clients which ports to use to contact the services
            they are trying to reach. This model weakens system security by introducing another
            privileged daemon which may be directly attacked, and is unnecessary because RPC was
            never adopted by enough services to risk using up all the ports on a system.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Unfortunately, the portmapper is central to RPC design, so it cannot be disabled if your
            site is using any RPCbased services, including NFS, NIS (see Section 3.2.4 for
            information about NIS, which is not recommended), or any third-party or custom RPC-based
            program. If none of these programs are in use, however, portmap should be disabled to
            improve system security. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            In order to get more information about whether portmap may be
            disabled on a given host, query the local portmapper using the command: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            If the only services listed are portmapper and status, it is safe to disable the
            portmapper. If other services are listed and your site is not running NFS or NIS,
            investigate these services and disable them if possible.</xccdf:description>

            machine shares NFS filesystems. If the machine is an NFS server, it may be simpler to
            use an IP netblock specification, such as 10.3.2. (this is the TCP Wrappers syntax
            representing the netblock 10.3.2.0/24), or a hostname specification, such as

            The /etc/hosts.allow
            and /etc/hosts.deny files are used by TCP Wrappers to determine whether specified remote
            hosts are allowed to access certain services. The default portmapper shipped with RHEL5
            has TCP Wrappers support built in, so this specification can be used to provide some

            Firewalling should be done at each host and at the border firewalls to protect the NFS
            daemons from remote access, since NFS servers should never be accessible from outside
            the organization. However, by default, the portmapper assigns each NFS service to a port
            dynamically at service startup time. Dynamic ports cannot be protected by port filtering
            firewalls such as iptables (Section 2.5.5). <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            Therefore, restrict each service to always
            use a given port, so that firewalling can be done effectively. Note that, because of the
            way RPC is implemented, it is not possible to disable the portmapper even if ports are
            assigned statically to all RPC services.</xccdf:description>

            considered risky because of the possibility that an adversary could intercept the
            request and substitute a malicious file. Allowing setuid files to be executed from

              made from ports less than 1024. If your organization has control over machines
              connected to its network, and if NFS requests are prohibited at the border firewall,
              this offers some protection against malicious requests from unprivileged users.
              Therefore, the default should not be changed.</xccdf:description>

          provide DNS service. BIND is the Internet standard Unix nameserver, and, while it has had
          security problems in the past, it is also well-maintained and Red Hat is likely to quickly
          issue updates in response to any problems discovered in the future. In addition, BIND
          version 9 has new security features and more secure default settings than earlier
          versions. In particular, BIND version 4 is no longer recommended for production use, and
          BIND4 servers should be upgraded to a newer version as soon as possible.</xccdf:description>

            Chroot jails are not foolproof. However, they serve to make it more difficult for a
            compromised program to be used to attack the entire host. They do this by restricting a
            program's ability to traverse the directory upward, so that files outside the jail are
            not visible to the chrooted process. Since RHEL5 supports a standard mechanism for
            placing BIND in a chroot jail, you should take advantage of this feature. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Note: If you
            are running BIND in a chroot jail, then you should use the jailed named.conf as the
            primary nameserver configuration file. That is, when this guide recommends editing
            /etc/named.conf, you should instead edit /var/named/chroot/etc/named.conf.</xccdf:description>

            Enterprise nameservers generally serve two
            functions. One is to provide public information about the machines in a domain for the
            benefit of outside users who wish to contact those machines, for instance in order to
            send mail to users in the enterprise, or to visit the enterprise's external web page.
            The other is to provide nameservice to client machines within the enterprise. Client
            machines require both private information about enterprise machines (which may be
            different from the public information served to the rest of the world) and public
            information about machines outside the enterprise, which is used to send mail or visit
            websites outside of the organization. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            In order to provide the public nameservice
            function, it is necessary to share data with untrusted machines which request it —
            otherwise, the enterprise cannot be conveniently contacted by outside users. However,
            internal data should be protected from disclosure, and serving irrelevant public name
            queries for outside domains leaves the DNS server open to cache poisoning and other
            attacks. Therefore, local network nameservice functions should not be provided to
            untrusted machines. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Separate machines should be used to fill these two functions whenever possible.</xccdf:description>

            The view feature is provided by BIND9 as a way to allow a single nameserver to make
            different sets of data available to different sets of clients. If possible, it is always
            better to run external and internal nameservers on separate machines, so that even
            complete compromise of the external server cannot be used to obtain internal data or
            confuse internal DNS clients. However, this is not always feasible, and use of a feature
            like views is preferable to leaving internal DNS data entirely unprotected. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            Note: As
            shown in the example, database files which are required for recursion, such as the root
            hints file, must be available to any clients which are allowed to make recursive
            queries. Under typical circumstances, this includes only the internal clients which are
            allowed to use this server as a general-purpose nameserver.</xccdf:description>

            The BIND transaction signature (TSIG) functionality
            allows primary and secondary nameservers to use a shared secret to verify authorization
            to perform zone transfers. This method is more secure than using IP-based limiting to
            restrict nameserver access, since IP addresses can be easily spoofed. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            However, if you
            cannot configure TSIG between your servers because, for instance, the secondary
            nameserver is not under your control and its administrators are unwilling to configure
            TSIG, you can configure an allow-transfer directive with numerical IP addresses or ACLs
            as a last resort. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Note: The purpose of the dnssec-keygen command is to create the shared
            secret string base64-key-string . Once this secret has been obtained and inserted into
            named.conf on the primary and secondary servers, the key files 
            Kdns.example.com.+NNN+MMMMM.key and Kdns.example.com.+NNN+MMMMM.private are no longer 
            needed, and may safely be deleted.</xccdf:description>

            Dynamic updates allow remote servers to add, delete, or modify any entries in your
            zone file. Therefore, they should be considered highly risky, and disabled unless there
            is a very good reason for their use. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            If dynamic updates must be allowed, IP-based ACLs
            are insufficient protection, since they are easily spoofed. Instead, use TSIG keys (see

              The use of non-anonymous FTP logins is strongly discouraged. Since SSH
              clients and servers are widely available, and since SSH provides support for a

              Historically, the file /etc/ftpusers
              contained a list of users who were not allowed to access the system via ftp. It was
              used to prevent system users such as the root user from logging in via the insecure
              ftp protocol. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              However, when the configuration option userlist_deny=NO is set, vsftpd
              interprets ftpusers as the set of users who are allowed to login via ftp. Since it
              should be possible for most users to access their accounts via secure protocols, it is
              recommended that this setting be used, so that non-anonymous ftp access can be limited
              to legacy users who have been explicitly identified.</xccdf:description>

            Anonymous FTP can be a convenient way to make files available for universal download.
            However, it is less common to have a need to allow unauthenticated users to place files
            on the FTP server. If this must be done, it is necessary to ensure that files cannot be
            uploaded and downloaded from the same directory.</xccdf:description>

            FTP is an older protocol which is not very compatible with firewalls.
            During the initial FTP dialogue, the client and server negotiate an arbitrary port to be
            used for data transfer. The ip conntrack ftp module is used by iptables to listen to
            that dialogue and allow connections to the data ports which FTP negotiates. This allows
            an FTP server to operate on a machine which is running a firewall.</xccdf:description>

            A default installation of Apache includes a plethora of
            'dynamically shared objects' (DSO) that are loaded at run-time. Unlike the
            aforementioned 'compiled-in' modules, a DSO can be disabled in the configuration file by
            removing the corresponding LoadModule directive. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Note: A DSO only provides additional
            functionality if associated directives are included in the Apache configuration file. It
            should also be noted that removing a DSO will produce errors on Apache startup if the
            configuration file contains directives that apply to that module. Refer to
            http://httpd.apache.org/docs/ for details on which directives are associated with each
            DSO. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Follow each DSO removal, the configuration can be tested with the following command
            to check if everything still works: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            The purpose of each of
            the modules loaded by default will now be addressed one at a time. If none of a module's

            The AuthType directive

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The AuthUserFile and AuthGroupFile directives point to the

            The require user directive restricts access
            to a single user. The require group directive restricts access to multiple users in a

            Note: Make sure the AuthUserFile and AuthGroupFile locations are
            outside the web server document tree to prevent remote clients from having access to

              physically secure system, generate a key pair for the web server: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              When prompted,
              enter a strong, unique passphrase to protect the web server key pair. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              Next, generate a Certificate Signing Request (CSR) from the key for the CA: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              Enter the passphrase for the web server key pair
              and then fill out the fields as completely as possible (or hit return to accept
              defaults); the Common Name field is especially important. It must match the
              fullyqualified domain name of your server exactly (e.g. www.example.com) or the
              certificate will not work. The /etc/pki/tls/openssl.conf file will determine which
              other fields (e.g. Country Name, Organization Name, etc) must match between the server
              request and the CA. Leave the challenge password and an optional company name blank.
              Next, the web server CSR must be signed to create the web server certificate. You can
              either send the CSR to an established CA or sign it with your CA. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              To sign httpserver.csr using your CA: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:code xmlns:xhtml="http://www.w3.org/1999/xhtml"># openssl ca -in httpserver.csr -out httpservercert.pem<xhtml:br/></xhtml:code>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              When prompted, enter the CA passphrase to continue and then complete the process. The
              httpservercert. pem certificate needed to enable SSL on the web server is now in the
              directory. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              Finally, the web server key and certificate file need to be moved to the
              web server. Use removable media if possible. Place the server key and certificate file
              in /etc/pki/tls/http/, naming them serverkey.pem and servercert.pem, respectively.</xccdf:description>

            Denial-of-service attacks are difficult to detect and prevent
            while maintaining acceptable access to authorized users. However, there are a number of
            traffic-shaping modules that attempt to address the problem. Well-known DoS protection
            modules include: mod_throttle mod_bwshare mod_limitipconn mod_dosevasive It is
            recommended that denial-of-service prevention be implemented for the web server.
            However, this guide leaves specific configuration details to the discretion of the

            SSL should be used to encrypt network traffic between the

            addition, protecting mail as it is downloaded is a privacy measure, and clients may use
            SSL certificates to authenticate the server, preventing another system from
            impersonating the server. See Section 2.5.6 for general SSL information, including the
            setup of a Certificate Authority (CA).</xccdf:description>

              Note: The following steps should be performed on your CA

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              Next, generate a
              certificate signing request (CSR) for the CA to sign, making sure to enter the
              server's fully-qualified domain name when prompted for the Common Name: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              Next, the mail server CSR must be
              signed to create the Dovecot server certificate. You can either send the CSR to an
              established CA or sign it with your CA. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:code xmlns:xhtml="http://www.w3.org/1999/xhtml"># openssl ca -in imapserver.csr -out imapservercert.pem <xhtml:br/></xhtml:code>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              This step creates a private key,
              imapserverkey.pem, and a public certificate, imapservercert.pem. The Dovecot server
              will use these to prove its identity by demonstrating that it has a certificate which
              has been signed by a CA. POP3 or IMAP clients at your site should only be willing to
              provide users' credentials to a server they can authenticate.</xccdf:description>

            IMAP and POP3 are
            remote authenticated protocols, meaning that the server must accept remote connections
            from anyone, but provide substantial services only to clients who have successfully
            authenticated. To protect against security problems, Dovecot splits these functions into
            separate server processes. The imap-login and/or pop3-login processes accept connections
            from unauthenticated users, and only spawn imap or pop3 processes on successful
            authentication. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            However, the imap-login and pop3-login processes themselves may contain
            vulnerabilities. Since each of these processes operates as a daemon, handling multiple
            sequential client connections from different users, bugs in the code could allow
            unauthenticated users to steal credential data. If the login_process_per_connection
            option is enabled, then a separate imap-login or pop3-login process is created for each
            new connection, protecting against this class of problems. This option has an efficiency
            cost, but is strongly recommended. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            If the mail_drop_priv_before_exec option is on, the
            imap-login or pop3-login process will drop privileges to the user's ID after
            authentication and before executing the imap or pop3 process itself. Under some very
            limited circumstances, this could protect against privilege escalation by authenticated
            users. However, if the mail executable option is used to run code before starting each
            user's session, it is important to drop privileges to prevent the custom code from
            running as root.</xccdf:description>

            There are two kinds of security in Samba, share-level (share)
            and user-level. User-level security is further subdivided into four separate
            implementations: user, domain, ads, and server. It is recommended that the share and
            server security modes not be used. In share security, everyone is given the same
            password for each share, preventing individual user accountability. server security mode
            has been superseded by the domain and ads security modes. It may now be considered
            obsolete. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The security parameter is set in the [global] section of the Samba
            configuration file. It determines how the server will handle user names and passwords.
            Some security modes require additional parameters, such as workgroup, realm, or password
            server names. All security modes will require that each remote user have a matching
            local account. One workaround to this problem is to use the winbindd daemon. Please
            consult the official Samba documentation to learn more.</xccdf:description>

              domain mode is used for any machine
              that will act as a domain member server. It lets Samba know that the authentication
              information it needs can be found on another machine. Primary and Backup Domain
              Controllers host copies of this information. Samba will try to automatically determine
              which machine it should authenticate against on a domain network. If this detection
              fails, it may be necessary to specify the location manually. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              Unlike the Microsoft
              Windows implementation of the SMB standard, a Samba machine can freely change roles
              within a domain without requiring that the machine be reinstalled (such roles include
              primary and backup domain controllers, domain member servers, and ordinary domain
              workstations). However, there are some limitations on how each machine can fulfill
              each role in a mixed network.</xccdf:description>

              parameter appropriately and configure the local copy of Kerberos. If necessary, it is
              also possible to manually set the password server parameter. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

              Currently, it is possible to act as an
              Active Directory domain member server, but not as a domain controller. Be sure to
              operate in mixed mode. Native mode may not work yet in current versions of Samba.
              Future support for ADS should be forthcoming in Samba 4. See the Samba project web

            When acting as a PDC, it becomes
            necessary to create and store Machine Trust Accounts for each machine that joins the
            domain. On a Microsoft Windows PDC, this account is created with the Server Manager
            tool, but on a Samba PDC, two accounts must be created. The first is the local machine
            account, and the second is the Samba account. For security purposes, it is recommended
            to let Samba create these accounts on-the-fly. When Machine Trust Accounts are created
            manually, there is a small window of opportunity in which a rogue machine could join the
            domain in place of the new server.</xccdf:description>

              Require packet signing of clients who mount Samba shares using the mount.cifs program (e.g., those who
              specify shares in /etc/fstab). To do so, ensure that signing options (either sec=krb5i or sec=ntlmv2i) are
              used.<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              See the mount.cifs(8) man page for more information. A Samba client should only communicate with servers
              who can support SMB packet signing. Packet signing can prevent man-in-the-middle attacks which modify SMB
              packets in transit.</xccdf:description>

            By default, Samba utilizes the CUPS printing service to enable
            printer sharing with Microsoft Windows workstations. If there are no printers on the
            local machine, or if printer sharing with Microsoft Windows is not required, disable the
            printer sharing capability by commenting out the following lines, found in /etc/
            samba/smb.conf: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            There may be other options present, but these are the only options
            enabled and uncommented by default. Removing the [printers] share should be enough for
            most users. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            If the Samba printer sharing capability is needed, consider disabling the
            Samba network browsing capability or restricting access to a particular set of users or
            network addresses. Set the valid users parameter to a small subset of users or restrict
            it to a particular group of users with the shorthand @. Separate each user or group of
            users with a space. For example, under the [printers] share: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            [printers] <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The CUPS service is capable of sharing printers with other Unix and
            Linux machines on the local network without the Samba service. The Samba service is only
            required when a Microsoft Windows machine needs printer access on a Unix or Linux host.</xccdf:description>

            The default Iptables configuration does not allow inbound access to the ports used by
            the Samba service. This modification allows that access, while keeping other ports on
            the server in their default protected state. Since these ports are frequent targets of
            network scanning attacks, restricting access to only the network segments which need to
            access the Samba server is strongly recommended. See Section 2.5.5 for more information

        A proxy server is a very desirable target for a potential adversary

        that purpose alone and be stored in a physically secure location. The system's default proxy
        server software is Squid, and provided in an RPM package of the same name.</xccdf:description>

                      <xccdf:description xml:lang="en">
            Note: Authentication cannot be used in the case of transparent
            proxies due to limitations of the TCP/IP protocol. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Similar to web servers, two of the
            available options are Basic and Digest authentication. The other options are NTLM and
            Negotiate authentication. As noted in Section 3.16.3.5, Basic authentication transmits
            passwords in plain-text and is susceptible to passive monitoring. If network sniffing is
            a concern, basic authentication should not be used. Negotiate is the newest and most
            secure protocol. It attempts to use Kerberos authentication and falls back to NTLM if it
            cannot. It should be noted that Kerberos requires a third-party Key Distribution Center
            (KDC) to function properly, whereas the other methods of authentication are two-party
            schemes. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Squid also offers the ability to choose a custom external authenticator.
            Designating an external authenticator (also known as a 'helper' module) allows Squid to
            offer pluggable third-party authentication schemes. LDAP is one example of a helper
            module that exists and is in use today. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            There are comments under the auth_param tag
            inside /etc/squid/squid.conf that provide extensive detail on how to configure each of
            these methods. If authentication is necessary, choose a method of authentication and
            configure appropriately. The recommended minimum configurations illustrated for each
            method are acceptable. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            To force an ACL (as discussed in Section 3.19.2.5) to require
            authentication, use the following directive: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            acl name-of-ACL proxy_auth REQUIRED <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Note:
            The keyword REQUIRED can be replaced with a user or list of users to further restrict
            access to a smaller subset of users.</xccdf:description>

                      <xccdf:description xml:lang="en">
            The acl and http access tags are used in combination to allow filtering based on a series of
            access control lists. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            Squid has a list of default ACLs for localhost, SSL ports, and
            'safe' ports. Following the definition of these ACLs, a series of http access directives
            establish the following default filtering policy: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:ul xmlns:xhtml="http://www.w3.org/1999/xhtml"><xhtml:li>Allow cachemgr access only from localhost </xhtml:li><xhtml:li>Allow access to only ports in the 'safe' access control list</xhtml:li><xhtml:li>Limit CONNECT method to SSL ports only</xhtml:li><xhtml:li>Allow access from localhost</xhtml:li><xhtml:li>Deny all other requests</xhtml:li></xhtml:ul><xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The
            default ACL policies are reasonable from a security standpoint. However, the number of
            ports listed as 'safe' could be significantly trimmed depending on the needs of your
            network. Out of the box, ports 21, 70, 80, 210, 280, 443, 488, 591, 777, and 1025
            through 65535 are all considered safe. Some of these ports are associated with
            deprecated or rarely used protocols. As such, this list could be trimmed to further
            tighten filtering. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            The following actions should be taken to tighten the ACL policies: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            The ICP protocol is a cache communication protocol that allows
            multiple Squid servers to communicate. The ICP protocol was designed with no security in
            mind, relying on user-defined access control lists alone to determine which ICP messages
            to allow. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            If a Squid server is standalone, the ICP port should be disabled by adding or
            correcting the following line in the configuration file: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            If the Squid server
            is meant to speak with peers, strict ACLs should be established to only allow ICP
            traffic from trusted neighbors. To accomplish this, add or correct the following lines:<xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

            The default behavior of Squid is to record its log messages in
            /var/log/squid.log. This behavior can be supplemented so that Squid also sends messages
            to syslog as well. This is useful for centralizing log data, particularly in instances

            Since Squid is loaded by the system's service utility, it
            starts as root and then changes its effective UID to the UID specified by the cache

            maintains a saved UID of root even after changing its effective UID. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
            To prevent this
            undesired behavior, Squid must either be configured to run in a chroot environment or it
            must be executed by a non-privileged user in non-daemon mode (the service utility must
            not be used).</xccdf:description>

                        <xccdf:description xml:lang="en">
              Chrooting Squid can be a very complicated task. Documentation
              for the process is vague and a great deal of trial and error may be required to
              determine all the files that need to be transitioned over to the chroot environment.
              Therefore, this guide recommends instead the method detailed in Section 3.19.2.9.2 to
              lower privileges. If chrooting Squid is still desired, it can be enabled with the
              following directive in the configuration file: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              chroot chroot-path <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              Then, all the
              necessary files used by Squid must be copied into the chroot-path directory. The
              specifics of this step cannot be covered in this guide because they are highly
              dependent on the external programs used in the Squid configuration. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              Note: The strace
              utility is a valuable resource for discovering the files needed for the chroot
              environment.</xccdf:description>

              he following modification to /etc/init.d/squid forces the

              <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
              Making this change prevents Squid from writing its pid to
              /var/run. This pid file is used by service to check to see if the program started
              successfully. Therefore, a new location must be chosen for this pid file that the
              squid user has access to, and the corresponding references in /etc/init.d/squid must
              be altered to point to it. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>

          multiple security models implemented by SNMP cannot be fully covered here so only the
          following general configuration advice can be offered: <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/>
          <xhtml:ul xmlns:xhtml="http://www.w3.org/1999/xhtml"><xhtml:li>use only SNMP version 3 security
              models and enable the use of authentication and encryption for those </xhtml:li><xhtml:li>write access to the
              MIB (Management Information Base) should be allowed only if necessary </xhtml:li><xhtml:li>all access to the
              MIB should be restricted following a principle of least privilege </xhtml:li><xhtml:li>network access should
              be limited to the maximum extent possible including restricting to expected network
              addresses both in the configuration files and in the system firewall rules </xhtml:li><xhtml:li>ensure SNMP
              agents send traps only to, and accept SNMP queries only from, authorized management
              stations </xhtml:li><xhtml:li>ensure that permissions on the snmpd.conf configuration file (by default, in
              /etc/snmp) are 640 or more restrictive </xhtml:li><xhtml:li>ensure that any MIB files' permissions are also
              640 or more restrictive</xhtml:li></xhtml:ul></xccdf:description>
