Ensure No Daemons are Unconfined by SELinux
An XCCDF Rule
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 init process, they inherit the unconfined_service_t context.
To check for unconfined daemons, run the following command:
$ sudo ps -eZ | grep "unconfined_service_t"It should produce no output in a well-configured system.
warning alert: Warning
Automatic remediation of this control is not available. Remediation
can be achieved by amending SELinux policy or stopping the unconfined
daemons as outlined above.
Rationale
Daemons which run with the unconfined_service_t context may cause AVC denials,
or allow privileges that the daemon does not require.
