Seven Deadliest Network Attacks identifies seven classes of network attacks and discusses how the attack works, including tools to accomplish the attack, the risks of the attack, and how to defend against the attack.
The book consists of seven chapters that deal with the following attacks: (i) denial of service; (ii) war dialing; (iii) penetration testing; (iv) protocol tunneling; (v) spanning tree attacks; (vi) man-in-the-middle; and (vii) password replay. These attacks are not mutually exclusive and were chosen because they help illustrate different aspects of network security. The principles on which they rely are unlikely to vanish any time soon, and they allow for the possibility of gaining something of interest to the attacker, from money to high-value data.
This book is intended to provide practical, usable information. However, the world of network security is evolving very rapidly, and the attack that works today may (hopefully) not work tomorrow. It is more important, then, to understand the principles on which the attacks and exploits are based in order to properly plan either a network attack or a network defense.

Attacks may and will change, but the principles, assumptions and practices being used will likely remain the same for quite some time, and the authors did a good job explaining them. And that is the real value of this book--Zeljka Zorz, Help Net Security

"[Knapp] provides a quite readable introduction to industrial networks and how familiar security principles can be translated to apply in this complex area…. Whether you are charged with defending an industrial network or curious about all the "buzz" over SCADA security, Knapp's book will provide a solid introduction to this fascinating area. Definitely a recommended read."--IEEE
