Check Text (C-248898r991589_chk)
Verify that if the system has a display server installed, it is authorized.
Check for the display server package with the following example command:
$ sudo rpm -qa | grep xorg | grep server
Ask the System Administrator if use of the display server is an operational requirement.
If the use of a display server on the system is not documented with the Information System Security Officer (ISSO), this is a finding.
Fix Text (F-52286r780259_fix)
Document the requirement for a display server with the ISSO or remove the related packages with the following example command:
$ sudo rpm -e xorg-x11-server-common
