re: securing linux
Well, you can start by reading this:
That should get you as far as understanding what goes into securing a linux host and take you through many of the steps you'll want to take as well.
You can also use Bastille, which automates a large part of the process:
To round out the above two, you may want to check out NSA's Security Enhanced Linux (http://www.nsa.gov/selinux/) and read through the documentation.
Lastly, try www.google.com. Searching for "hardening linux" or "linux security" turns up a ton of relevant hits.

You can also start by stopping....that is stopping all running services that you don't need (or don't use) Redhat has a way of assuming that you will just use all these random services and such. So start from square zero and work up from there.
A good general knowledge of exactly what is running on your system will go a long way towards deciding what type of security measures you should implement.
Good luck with ol' Redhat. And when you've finished learning about the wrong way to do most things... load up a real *nix. hehehe (FreeBSD,OPENBSD,etc. etc.) That'll teach you more about network security than linux. IMHO.
Mankind have a great aversion to intellectual labor; but even supposing knowledge to be easily attainable, more people would be content to be ignorant than would take even a little trouble to acquire it.
