There are many ways that a potential attacker can intercept information, or learnmore about the sender, as the information travels over a network. Silence on the Wireuncovers these silent attacks so that system administrators can defend against them,as well as better understand and monitor their systems.

Silence on the Wire dissects several unique and fascinating security and privacy problems associated with the technologies and protocols used in everyday computing, and shows how to use this knowledge to learn more about others or to better defend systems. By taking an in depth look at modern computing, from hardware on up, the book helps the system administrator to better understand security issues, and to approach networking from a new, more creative perspective. The sys admin can apply this knowledge to network monitoring, policy enforcement, evidence analysis, IDS, honeypots, firewalls, and forensics.
