Query: Complete Handbook of Known Information

Although this book is informative for someone new to computer security, it tells no new tales for someone who already knows something about computer security.Almost all the other books have the same information presented here; some of the other books even present the information better. This is NOT a hacker's guide. This is NOT a manual for computer security professionals. This is a book written to earn the author some quick bucks.The author may very well be knowledgeable, but that knowledge was not presented here in the book.For a good security book, look elsewhere.
