man xorg.conf

        Option "DontZap"  "boolean"
              This disallows the use of the Ctrl+Alt+Backspace sequence.  That
              sequence is normally used to terminate the  Xorg  server.   When
              this option is enabled, that key sequence has no special meaning
              and is passed to clients.  Default: off.

Another solution is to use a graphical login manage (xdm, gdm, kdm) instead of manually starting X from the commandline.

This way, if they kill the X server, the login manager restarts instead of dropping them to a live shell.

Even if you kill CTRL+ALT+Backspace, they can still CTRL+ALT+F1, hit CTRL+C to kill startx, and have access to your live login shell.

This can also be disabled in xorg.conf

       Option "DontVTSwitch"  "boolean"
              This disallows the use of the  Ctrl+Alt+Fn  sequence  (where  Fn
              refers  to one of the numbered function keys).  That sequence is
              normally used to switch to another "virtual terminal" on operat-
              ing  systems  that  have  this  feature.   When  this  option is
              enabled, that key sequence has no special meaning and is  passed
              to clients.  Default: off.

Even better would be locking your workstation when you're not sitting in front of it, I've learned the hard way that you should always do this when other people can readily access your workstation ... You go to the toilet, and when you come back you discover that some stupid hack (coworker, friend of a coworker, kid, customer, whatever) closed all your windows, changed all kinds of settings, and who knows what else they did.

It's not even a matter of trust or security, just convenience and time-saving.

xlockmore can disable all CTRL+ALT key combinations.

Control-Alt-delete (to restart the system) is managed by the operating system. As for disabling it, the FAQs gave this answer, but I am not sure if it will work in X. You may have to lock C-A-D using X's keymapping too.
