"Real 802.11 Security provides clear descriptions of current and emerging security techniques.
The authors handle complex topics nicely, and offer significant clarification of IEEE draft
standards."
-Russ Housley, IETF Security Area Director and founder of Vigil Security, LLC
"This is certainly the definitive text on the internals of 802.11 security!"
-John Viega, founder and chief scientist, Secure Software, Inc.
"This book keeps the exposition as straightforward as possible and enables you to cut through
the maze of acronyms, hacking tools, rumored weaknesses, and vague vendor security claims to
make educated security decisions when purchasing or deploying WLAN."
-Simon Blake-Wilson, Director of Information Security, BCI
Business professionals and advanced home users are captivated by the convenience of working
on wireless networks. But how can privacy and security be maintained effectively? Real 802.11
Security describes an entirely new approach to wireless LAN security based on the latest
developments in Wi-Fi technology. This is the book that will show you how to establish real
security within your Wi-Fi LAN.
Recent developments in Wi-Fi security achieve what no amount of reconfiguration can do: They
solve the problem at the source. Wi-Fi Protected Access (WPA) repairs weaknesses in existing
Wi-Fi systems and is designed to allow software upgrades. The upcoming 802.11i standard will
offer a much higher level of security than previously offered and will provide flexible, extremely
secure solutions for future products.
Real 802.11 Security addresses the theory, implementations, and reality of Wi-Fi security. It
provides an overview of security issues, explains how security works in Wi-Fi networks, and
explores various security and authentication protocols. The book concludes with an in-depth
discussion of real-world security issues and attack tools.
