"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.
Written by two experts in wireless security, Jon Edney and William
Arbaugh, this book shows you how to stay informed and aware when
making security decisions, and what steps you can take to implement the
most effective, proactive wireless security now and in the future.
