Fix Recommendation

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

Check Contents

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.
