Linux security scripts

Can someone point me to an article on the net or some existing scripts that I can run as administrator so that I know my Linux site has not been compromised by an outsider?  My son set up my Red Hat 6.1 site this summer and I've been using Unix for over 20 years but I just don't have time to go fishing to find this solution.  We have our system on the net via an ADSL line so I know he made the system fairly secure, I just get hyper about these things!  ;-)

A this point there's not any foolproof way to tell if the system has already been compromised. To do so would require, amoung other things, comparing the binaries of sensitive programs against "known good" copies. There are utilities like Tripwire that are used for intrusion detection, but they rely on having built a "picture" of the system before it was is ever exposed.

There are security scanners, like Satan, that can scan a system from the network looking for "known" vulnerabilities. Even if the system was originally set up as secure, changes in packages, usage, and practices may mean that it's not as secure now.

A good reference, with pointers to a lot more good references and tools is howto.tucows.com/LDP/HOWTO/Security-HOWTO.html.
