Also, check www.redhat.com's support page for the security updates. There are several affected packages. You probably will want to keep this machine *out* of graphics mode. I've heard from a number of sources that X servers are notorious for being security holes. Also, only log in as root if absolutely necessary. Log in as yourself and 'su' as needed to install programs. If you're doing a source install, only 'su' when you get to the 'make install' stage so you aren't creating programs with root privleges. What I've picked up (I'm neither a Linux nor a security expert) is that you can never make a system wholly hack-proof, you can simply make it increasingly difficult for the hacker to get in, make changes, and cover his tracks. Also, are you a member of a local Linux users' group? Most of the people in these groups are IS professionals. They've probably got their own tips and recommendations.
