Description |
---|
A locally logged-in user who presses Ctrl-Alt-Delete, when at the console, can reboot the system. If accidentally pressed, as could happen in the case of mixed OS environment, this can create the risk of short-term loss of availability of systems due to unintentional reboot. In the GNOME graphical environment, risk of unintentional reboot from the Ctrl-Alt-Delete sequence is reduced because the user will be prompted before any action is taken. |

By default, the system includes the following line in "/etc/init/control-alt-delete.conf" to reboot the system when the Ctrl-Alt-Delete key sequence is pressed: exec /sbin/shutdown -r now "Ctrl-Alt-Delete pressed" To configure the system to log a message instead of rebooting the system, add the following line to "/etc/init/control-alt-delete.override" to read as follows: exec /usr/bin/logger -p security.info "Ctrl-Alt-Delete pressed" |
