Going even further than what Nate said, remove all accounts you don't
need. Give only accounts to those who need to admin the box, other than
that DO NOT give away accounts.

Make sure the security log files sent by email are being sent to the
correct persons.

Remove /usr/src and compile kernels on a secondary host so you are sure
that compiling stuff on the firewall is hard after a compromise.

Use ssh and ditch telnet.
