Full Description
The Chief Information Warfare Officer for the entire United States teaches you how to protect your corporate network. This book is a training aid and reference for intrusion detection analysts. While the authors refer to research and theory, they focus their attention on providing practical information. The authors are literally the most recognized names in this specialized field, with unparalleled experience in defending our country's government and military computer networks. New to this edition is coverage of packet dissection, IP datagram fields, forensics, and snort filters.
