OL 9 must be configured so that the x86 Ctrl-Alt-Delete key sequence is disabled.

| Finding ID | Version | Rule ID | IA Controls | Severity |

| Description | ||||
| A locally logged-on user who presses Ctrl-Alt-Delete when at the console can reboot the system. If accidentally pressed, as could happen in the case of a mixed OS environment, this can create the risk of short-term loss of availability of systems due to unintentional reboot. In a graphical user environment, risk of unintentional reboot from the Ctrl-Alt-Delete sequence is reduced because the user will be prompted before any action is taken. | ||||

Details
Check Text (C-271752r1091968_chk)
Verify that OL 9 is not configured to reboot the system when Ctrl-Alt-Delete is pressed with the following command:
$ systemctl status ctrl-alt-del.target
ctrl-alt-del.target
Loaded: masked (Reason: Unit ctrl-alt-del.target is masked.)
Active: inactive (dead)
If the "ctrl-alt-del.target" is loaded and not masked, this is a finding.
Fix Text (F-75709r1091967_fix)
Configure OL 9 to disable the ctrl-alt-del.target with the following command:
$ sudo systemctl disable --now ctrl-alt-del.target
$ sudo systemctl mask --now ctrl-alt-del.target
