Details
Check Text (C-252663r991589_chk)
Verify that the system is configured to boot to the command line:
$ systemctl get-default
multi-user.target
If the system default target is not set to "multi-user.target" and the Information System Security Officer (ISSO) lacks a documented requirement for a graphical user interface, this is a finding.
Fix Text (F-56069r818784_fix)
Document the requirement for a graphical user interface with the ISSO or reinstall the operating system without the graphical user interface. If reinstallation is not feasible, then continue with the following procedure:
Open an SSH session and enter the following commands:
$ sudo systemctl set-default multi-user.target
A reboot is required for the changes to take effect.
