Query: Worst Book Ever

Thank God I DID NOT BUY this book. I took 30 minutes to read this book at a bookstore and if you are interested in learning how to hack, then this book is not for you. This book DOES NOT SHOW YOU HOW TO HACK, it's just another ordinary book which shows you how to PREVENT a hacker from attacking your computer/network. Very disappointing. Even the information in this book that shows you how to prevent a hacker attack can be found online easily. This book is definatly not worth it.
