## ModSecurity 2.x Command-line build notes for Windows
by Tom Donovam, 4/2/2011
## Prerequisites:
Dependency | Tested with | Note
----|------|----
Microsoft Visual Studio C++ | Visual Studio 2013 (aka VC12) |
[CMake build system](http://www.cmake.org/) | CMake v3.8.2 |
[Apache 2.4.x](http://httpd.apache.org/) | Apache 2.4.27 | Apache must be built from source using the same Visual Studio compiler as mod_security.
[PCRE, Perl Compatible Regular Expression library](http://www.pcre.org/) | PCRE v8.40
[LibXML2](http://xmlsoft.org/) | LibXML2 v2.9.4 |
[Lua Scripting Language](http://www.lua.org/) | Lua v5.3.4
[cURL multiprotocol file transfer library](http://curl.haxx.se/) | cURL v7.54.0
## Before building
The directory where you build software from source ( ``C:\work`` in this exmaple)
must contain the Apache source you used to build the Apache web serverand the mod_security source
Apache source is in C:\work\httpd-2.4.27 in this example.
Apache has been installed to C:\Apache2427 in this example.
Mod_security source is in C:\work\mod_security in this example.
## Download and untar the prerequisite library sources:
Download pcre-8.40.tar.gz from ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/
untar it into C:\work\ creating C:\work\pcre-8.40
Download libxml2-2.9.4.tar.gz from ftp://xmlsoft.org/libxml2/
untar it into C:\work\ creating C:\work\libxml2-2.9.4
Download lua-5.3.4.tar.gz from http://www.lua.org/ftp/
untar it into C:\work\ creating C:\work\lua-5.3.4
Download curl-7.54.0.tar.gz from http://curl.haxx.se/download.html
untar it into C:\work\ creating C:\work\curl-7.54.0
## Setup your build environment:
1. The ``PATH`` environment variable must include the Visual Studio variables as set by ``vsvars32.bat``
2. The ``PATH`` environment variable must also include the CMAKE ``bin\`` directory
3. Set an environment variable to the Apache source code directory:
```
SET HTTPD_BUILD=C:\work\httpd-2.4.27
```
### Optional:
If OpenSSL and zlib support were included when you built Apache 2.4, and you want them available to LibXML2 and cURL
1. Ensure that cURL and LibXML2 can find the OpenSSL and zlib includes and libraries that Apache was built with.
```
SET INCLUDE=%INCLUDE%;%HTTPD_BUILD%\srclib\openssl\inc32;%HTTPD_BUILD%\srclib\zlib
SET LIB=%LIB%;%HTTPD_BUILD%\srclib\openssl\out32dll;%HTTPD_BUILD%\srclib\zlib
```
2. Ensure that cURL and libXML2 don't use the static zlib library: ``zlib.lib``. Force cURL and libXML2 to use ``zdll.lib`` instead, requiring ``zlib1.dll`` at runtime:
```
IF EXIST %HTTPD_BUILD%\srclib\zlib\zlib.lib DEL %HTTPD_BUILD%\srclib\zlib\zlib.lib
```
## Build
### PCRE-8.40
CD C:\work\pcre-8.40
CMAKE -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=RelWithDebInfo -DBUILD_SHARED_LIBS=True
NMAKE
### LibXML2-2.9.4
CD C:\work\libxml2-2.9.4\win32
CSCRIPT configure.js iconv=no vcmanifest=yes zlib=yes
NMAKE -f Makefile.msvc
### Lua-5.3.4
CD C:\work\lua-5.3.4\src
CL /Ox /arch:SSE2 /GF /GL /Gy /FD /EHsc /MD /Zi /TC /wd4005 /D "_MBCS" /D "LUA_CORE" /D "LUA_BUILD_AS_DLL" /D "_CRT_SECURE_NO_WARNINGS" /D "WIN32" /D "NDEBUG" /D "_CONSOLE" /D "_WIN32" /D "_WINDLL" /c *.c
DEL lua.obj luac.obj
LINK /DLL /LTCG /DEBUG /OUT:lua5.1.dll *.obj
IF EXIST lua5.1.dll.manifest MT -manifest lua5.1.dll.manifest -outputresource:lua5.1.dll;2
### cURL-7.54.0
CD C:\work\curl-7.54.0
CMAKE -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=RelWithDebInfo -DBUILD_SHARED_LIBS=True -DCURL_ZLIB=True
NMAKE
### ModSecurity-2.9.x
CD C:\work\mod_security\apache2
NMAKE -f Makefile.win APACHE=C:\Apache2427 PCRE=C:\work\pcre-8.40 LIBXML2=C:\work\libxml2-2.9.4 LUA=C:\work\lua-5.3.4\src
## Install ModSecurity and run Apache
Copy these five files to ``C:\Apache2427\bin``:
C:\work\pcre-8.40\pcre.dll C:\Apache2427\bin\
C:\work\lua-5.3.4\src\lua5.1.dll C:\Apache2427\bin\
C:\work\libxml2-2.9.4\win32\bin.msvc\libxml2.dll C:\Apache2427\bin\
C:\work\curl-7.54.0\libcurl.dll C:\Apache2427\bin\
C:\work\mod_security\apache2\mlogc-src\mlogc.exe
Copy this one file to ``C:\Apache2427\modules``:
C:\work\mod_security\apache2\mod_security2.so
You may also copy ``C:\work\curl-7.54.0\curl.exe`` to ``C:\Apache2427\bin``, if you want to use the cURL command-line program.
Download the core rules from http://sourceforge.net/projects/mod-security/files/modsecurity-crs/0-CURRENT/ and unzip them into ``C:\Apache2427\conf\modsecurity_crs``
Add configuration directives to your Apache conf\httpd.conf:
# mod_security requires mod_unique_id
LoadModule unique_id_module modules/mod_unique_id.so
# mod_security
LoadModule security2_module modules/mod_security2.so
<IfModule security2_module>
SecRuleEngine On
SecDataDir logs
Include conf/modsecurity_crs/*.conf
Include conf/modsecurity_crs/base_rules/*.conf
SecAuditEngine RelevantOnly
SecAuditLogRelevantStatus "^(?:5|4\d[^4])"
SecAuditLogType Serial
SecAuditLogParts ABCDEFGHZ
SecAuditLog logs/modsecurity.log
</IfModule>
## Optional: Build and configure the ModSecurity-2.x MLOGC piped-logging program
Edit the top of ``C:\work\mod_security\apache2\mlogc-src\Makefile.win`` and set your local paths
# Path to Apache httpd installation
BASE = C:\Apache2427
# Paths to required libraries
PCRE = C:\work\pcre-8.40
CURL = C:\work\curl-7.54.0
# Linking libraries
LIBS = $(BASE)\lib\libapr-1.lib \
$(BASE)\lib\libaprutil-1.lib \
$(PCRE)\pcre.lib \
$(CURL)\libcurl_imp.lib \
wsock32.lib
Build the ``mlogc.exe`` program:
CD C:\work\mod_security_trunk\mlogc
NMAKE -f Makefile.win
Copy ``mlocg.exe`` to ``C:\Apache2427\bin\``
Create a new command file ``C:\Apache2427\bin\mlogc.bat`` with one line:
C:\Apache2427\bin\mlogc.exe C:\Apache2427\conf\mlogc.conf
Create a new configuration file ``C:\Apache2427\conf\mlogc.conf`` to control the piped-logging program ``mlogc.exe``.
Here is an example ``conf\mlogc.conf``:
CollectorRoot "C:/Apache2427/logs"
ConsoleURI "https://localhost:8888/rpc/auditLogReceiver"
SensorUsername "test"
SensorPassword "testtest"
LogStorageDir "data"
TransactionLog "mlogc-transaction.log"
QueuePath "mlogc-queue.log"
ErrorLog "mlogc-error.log"
LockFile "mlogc.lck"
KeepEntries 0
ErrorLogLevel 2
MaxConnections 10
MaxWorkerRequests 1000
TransactionDelay 50
StartupDelay 5000
CheckpointInterval 15
ServerErrorTimeout 60
Change the SecAuditLog directive in ``conf\httpd.conf`` to pipe the log data to mlogc instead of writing them to a file:
SecAuditLog |C:/Apache2427/bin/mlogc.bat
|
