Fix Recommendation

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 authpriv.notice "Ctrl-Alt-Delete pressed"

Check Contents

To ensure the system is configured to log a message instead of rebooting the system when “Ctrl-Alt-Delete” is pressed, ensure the following line is in "/etc/init/control-alt-delete.override":

exec /usr/bin/logger -p authpriv.notice "Ctrl-Alt-Delete pressed"

If the system is not configured to block the shutdown command when “Ctrl-Alt-Delete” is pressed, this is a finding.
