Query: Excellent Primer!

This book is VERY well written. It was one of the very best technical books I have ever read. Some of the info is a little dated, but the topics discussed are GREAT history. I personally get tired of security writers dismissing older exploits as they are still being used today. In addition, the majority of the first half of the book is devoted to security background and explanation of the types of major exploits.This was the first tech book that I have ever read cover to cover. It was that interesting. The authors had a very conversational style that keeps you hooked and entertained.I HIGHLY recommend it.
