First, this book should be called The Engineers Guide to Implementing Security to Detect and Prevent Malicious Traffic in Your Network. This is a very thorough book on how to detect malicious traffic leaving a network (hence Extrusion), with great illustrations and walkthroughs. There are chapters on planning, deployment, tuning and other key, often overlooked, aspects surrounding the wonderful world of Intrusion Detection.
The first hint that this book was a bit different is noticed in the Foreward. Marcus Ranum wrote the forward, or I should say guided the direction of the Foreward. Marcus opts for an interview with the author, versus "telling you a bunch of stuff about the book". The Foreward is a must when browsing this book. Very creative, something perhaps missing in the world of Information Security these days.
