Intrusion detection is one of the hottest growing areas of network security. As the number of corporate, government, and educational networks grow and as they become more and more interconnected through the Internet, there is a correlating increase in the types and numbers of attacks to penetrate those networks. Intrusion Detection, Second Edition is a training aid and reference for intrusion detection analysts. This book is meant to be practical. 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. People travel from all over the world to hear them speak, and this book will be a distillation of that experience. The book's approach is to introduce and ground topics through actual traffic patterns. The authors have been through the trenches and give you access to unusual and unique data.
