Query: Excellent!!

This is a book that i would recommend to all system admins and anyone who works with networks and computers. This guy is simply amazing, all it is, being shared experiences from his job. But the tips he gives are priceless... a little social engineering here a little hacking there...BUY this book if you are a cpu afficionado and want to learn even more and protect your systems.
