"I started messin' around with Port Knocking and Single Packet Authentication. I grabbed one of my favorite Linux reference guides; "Linux Firewalls" by Michael Rash. If you have not read this book, you're missin' out on the best thing since cornbread found pinto beans. Super friggen awesome book!

"On my way to chapter 12, I happened to stumble across Port Scan Attack Detector (PSAD). Wholly smokes! I have completely overlooked this awesome utility! PSAD at one time in a galaxy not so far away was called Bastille Linux NIDS. It is still part of the that awesome package but now called PSAD. If you are looking for a great OS hardening package look no further then: http://bastille-linux.sourceforge.net/"
