1.366 RHEL-10-700950

Information

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

GROUP ID: V-281298RULE ID: SV-281298r1166846

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 availability of systems 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 "CtrlAltDelBurstAction".

Update the "/etc/systemd/system.conf" configuration file as follows:

$ sudo vi /etc/systemd/system.conf

CtrlAltDelBurstAction=none

Reload the daemon for this change to take effect:

$ sudo systemctl daemon-reload
