Hey Guys,
I just discovered this site a couple of days ago...I'd already completed my requisite 3 weeks of study.
I didn't use an awful lot of resources..the Sybex (white & red)security+ book with extensive clarifications and additional research about IPSEC, Kerebos, and Digital signing from various internet sites.
Used a few free test questions from the back of the book and the free 100 questions from the Preplogic just to get a baseline that I was ready.
By the way for anyone that's interested there is a really good explanation of how certificates and signing works at
