Kevin there are a number of resources, some free, some not. Mileage will vary among them, as well as your knowledge of and expertise with linux already.
http://www.redhat.com/training/security/courses/ RHS333 is excellent if you have familiarity and solid, working knowledge of linux. RHS253 is excellent if you're a newbie. (yes, I'm biased since I work for RH and help develop/audit the security curriculum! By far the most expensive yet also the most in-depth and hands on) http://www.linuxsecurity.com/ a number of papers and articles there that may help you in your quest. http://bastille-linux.sourceforge.net/ good ol' bastille may help you at least partially. Now updated for 7.2 http://www.nusphere.com/secure_install_redhat.pdf short and basic information for 'locking down' Red Hat Linux. http://www.openna.com/products/books/securing-optimizing-linux/solrhe.htm Securing & Optimizing Linux PDF good luck with your tightening! :) PS, perhaps you should look into building a monolithic kernel so as to avoid module exploits? farmerdude > Any one out there know good reference for securing a > Linux 7.2 Server OS.
