Discussion

When the Ctrl-Alt-Del target is enabled, 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 systems availability due to unintentional reboot.

At the command line, run the following command to verify the ctrl-alt-del target is disabled and masked:

# systemctl status ctrl-alt-del.target --no-pager

Example output:

ctrl-alt-del.target
                Loaded: masked (Reason: Unit ctrl-alt-del.target is masked.)
                Active: inactive (dead)

If the "ctrl-alt-del.target" is not "inactive" and "masked", this is a finding.
