I have a line in /etc/inittab that says:
ca::ctrlaltdel:/etc/shutdown -t3 -rf now
I suspect you can put any program you like there instead of
/etc/shutdown. As someone has pointed out, you're adding no security
unless you have the machine (& not the keyboard) out of reach of the
user(s). Just disable ctrlaltdel & type "reboot" yourself. ..
