Have you ever wondered what a root kit was?

Bill Keys on LInuxSecurity.com does a really good job of both explaining what they are and some tips on how to avoid, remove, and detect them.  It is a nice easy read that will help you get a good understanding of the topic.  Check it out.

59 Open Source Security Tools...

While the title doesn't lie, "59 Open Source Tools That Can Replace Popular Security Software".  It probably should have been trimmed to 50.  Several of the packages are no longer being supported so be sure to go to the links and check the activity on the projects before committing.

This doesn't meant that like most articles like this there aren't a few new gems you may not of heard about before.  For me with this one it was the modsecurity package.  This pacakge is a plugin for Apache that aloow you to set up Web Server Firewall like functionality.  As I just had a friend get hacked becuase of a bug in PHP this seems like a great idea to me.  I am now going to look into whether we shouldn't be investigating.

A lot of my favorite security tools are on this list.  Things like SpamBayes, Spamassisin and Bacula just to name a few.  It's 4 pages but broken down in to nice list groupings.

 

DNS Security....

What the heck is DNSSEC? This article does a darn good job of explaining it.  If your company isn't using it might be time to get it roll-out. When you can this is a great way to secure your DNS and still let users work.
