GEN000000-LNX00580 - The x86 CTRL-ALT-DELETE key sequence must be disabled.

Information

Undesirable reboots can occur if the CTRL-ALT-DELETE key sequence is not disabled. Such reboots may cause a loss of data or loss of access to critical information.

Solution

Ensure the CTRL-ALT-DELETE key sequence has been disabled and attempts to use the sequence are logged.
In the /etc/inittab file replace:
ca::ctrlaltdel:/sbin/shutdown -t3 -r now
with
ca:nil:ctrlaltdel:/usr/bin/logger -p security.info 'Ctrl-Alt-Del was pressed'
