Title
The SUSE operating system must disable the x86 Ctrl-Alt-Delete key sequence. (Cat I impact)
Discussion
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.
Check Content
Verify the SUSE operating system is not configured to reboot the system when Ctrl-Alt-Delete is pressed. Check that the ctrl-alt-del.target is masked with the following command: > systemctl status ctrl-alt-del.target Loaded: masked (/dev/null; masked) Active: inactive (dead) If the ctrl-alt-del.target is not masked, this is a finding.
Fix Text
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 And reload the daemon to take effect > sudo systemctl daemon-reload
