1.367 RHEL-10-700960

Information

RHEL 10 must disable the x86 Ctrl-Alt-Delete key sequence.

GROUP ID: V-281299RULE ID: SV-281299r1166849

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 operating system environment, this can create the risk of short-term loss of systems 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.

Solution

Configure RHEL 10 to disable the "ctrl-alt-del.target" with the following command:

$ sudo systemctl disable --now ctrl-alt-del.target $ sudo systemctl mask --now ctrl-alt-del.target
