The x86 Ctrl-Alt-Delete key sequence must be disabled on OL 8.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
| V-248869 | OL08-00-040170 | SV-248869r991589_rule | CCI-000366 | high |
| 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 system availability 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. | ||||

Check Text (C-248869r991589_chk)
Verify OL 8 is not configured to reboot the system when Ctrl-Alt-Delete is pressed with the following command:
$ sudo systemctl status ctrl-alt-del.target | grep Loaded:
Loaded: masked (Reason: Unit ctrl-alt-del.target is masked.)
If the "ctrl-alt-del.target" Loaded: value is not set to "masked", this is a finding.
Fix Text (F-52257r833245_fix)
Configure the system to disable the Ctrl-Alt-Delete sequence for the command line with the following commands:
$ sudo systemctl disable ctrl-alt-del.target
$ sudo systemctl mask ctrl-alt-del.target
Created symlink /etc/systemd/system/ctrl-alt-del.target -> /dev/null
Reload the daemon to take effect:
$ sudo systemctl daemon-reload
