title: 'Ensure No Daemons are Unconfined by SELinux'
description: |-
Daemons for which the SELinux policy does not contain rules will inherit the
context of the parent process. Because daemons are launched during
startup and descend from the <tt>init</tt> process, they inherit the <tt>unconfined_service_t</tt> context.
<br />
<br />
To check for unconfined daemons, run the following command:
<pre>$ sudo ps -eZ | grep "unconfined_service_t"</pre>
It should produce no output in a well-configured system.
rationale: |-
Daemons which run with the <tt>unconfined_service_t</tt> context may cause AVC denials,
or allow privileges that the daemon does not require.

ocil: |-
Ensure there are no unconfined daemons running on the system,
the following command should produce no output:
<pre>$ sudo ps -eZ | grep "unconfined_service_t"</pre>
warnings:
- general: |-
Automatic remediation of this control is not available. Remediation
can be achieved by amending SELinux policy or stopping the unconfined
daemons as outlined above.
