it (after a reinstall).  I'm using Fedora Core 4.  I've taken all the
basic steps (shutting down unused services etc) and have done the
following:

Installed Smothwall on a separate box.
Installed & configured AIDE, Snort and chkrootkit

Ever tried tiger?

---Introduction

Tiger is a security tool that can be use both as a security audit and 
intrusion detection system. It supports multiple UNIX platforms and it 
is free and provided under a GPL license. Unlike other tools, Tiger 
needs only of POSIX tools and is written entirely in shell language.

I am in the process of configuring LIDS.  I'm using LIDS instead of
SELinux because it's easier for me to configure.

My next and final step will be to install mod_security.

I would suggest to use a static kernel without loadable modules.


Best regards
