Fix Recommendation

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

Check Contents

Verify RHEL 10 is configured to not reboot the system when Ctrl-Alt-Delete is pressed seven times within two seconds with the following command:

$ grep -iR CtrlAltDelBurstAction /etc/systemd/
/etc/systemd/system.conf:CtrlAltDelBurstAction=none

If the "CtrlAltDelBurstAction" is not set to "none", is commented out, or is missing, this is a finding.
