While there are a lot of books available on network security, most of them take
the approach of focusing on the attacks, on the hacks, and responding to those
on a one-by-one basis. This book does just the opposite, focusing on a holistic
approach to protecting your entire network. It covers all seven layers of the
Defense in Depth (DID) Model, as well as other material not covered in any
other books. DID refers to a system of combining defenses to provide added
protection. Since there are then multiple barriers between the attacker and the
attacked, this increases the level of security, and increases the cost of the attack
to the attacker. The authors are two senior members of Microsoft's Security
and Business Technology Unit (SBTU), and are among the most sought-after
speakers for security conferences. With security being such a strong focus at
Microsoft, this book is destined to become the standard guide for all network
administrators and architects who want to have the most secure Windows
network possible.
