“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:
