Theres two other books you might want to look into. One is something like "Hack Attacks Revealed" and "Steal This Book 2".
I found them at Barnes n Noble like a month ago. Steal this book 2 cost about $30, and hack attacks revealed cost around $50. Don't want to pay? Do what I do and just go in there whnever you got free time on your hands, find a nice cozy spot to sit, grab an iced mocha and just, read.
