I haven't touched this one but when you are looking for books you have to keep something in mind. Printed information should give you core information so as to a build a foundation for you to advance on your own afterwards. I have seen some books perusing through the local bookstore whilst having my coffee and see a little black hacker book hidden away that claims to be the encompassing guide to becoming a 1337 h4xx0r. Meh. Sorry to the point, find out what subjects are being covered, check the publication date (want to stay within the past couple of years if you can), and most importantly, check reviews.
