A comprehensive survey of computer network security concepts, methods, and practices. This authoritative volume provides an optimal description of the principles and applications of computer network security in particular, and cyberspace security in general. The book is thematically divided into three segments: Part I describes the operation and security conditions surrounding computer networks; Part II builds from there and exposes readers to the prevailing security situation based on a constant security threat; and Part III - the core - presents readers with most of the best practices and solutions currently in use. It is intended as both a teaching tool and reference. This broad-ranging text/reference comprehensively surveys computer network security concepts, methods, and practices and covers network security tools, policies, and administrative goals in an integrated manner. It is an essential security resource for undergraduate or graduate study, practitioners in networks, and professionals who develop and maintain secure computer network systems.

Industry Reviews

From the reviews:

"Computer security basics are covered in this book. ... it is targeted at students. This is evident in the very fluent and comprehensive writing style, and the generally good examples and review questions at the end of each chapter. ... the book is very well written ... with strong structuring. Every chapter has good references, and includes nice exercises and student projects as resources for lecturers. I recommend this book as a good foundational book and educational tool for network security in a university environment." (Andreas Tomek, Computing Reviews, April, 2006)
