RHEL 9 must disable the ability of a user to accidentally press Ctrl-Alt-Del and cause a system to shut down or reboot.
An XCCDF Rule
Description
A locally logged-in user who presses Ctrl-Alt-Del, when at the console, can reboot the system. If accidentally pressed, as could happen in the case of mixed OS environment, this can create the risk of short-term loss of availability of systems due to unintentional reboot.
