| Description |
|---|
| 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. |
| ℹ️ Check |
|---|
| 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. |
| ✔️ Fix |
|---|
| At the command line, run the following commands: # systemctl disable ctrl-alt-del.target # systemctl mask ctrl-alt-del.target # systemctl daemon-reload |
