內容描述

Mention wireless networks, and the question of security will soon follow.
It's not surprising that in spite of compelling business arguments for going
wireless, many companies are holding back because of security concerns. But,
while it's true that wireless networks create security issues that don't exist
in wired networks, the issues are not insurmountable. 802.11 Security
shows how you can plan for and successfully contend with security obstacles in
your wireless deployment. This authoritative book not only explains the security
issues, but shows you how to design and build a your own secure wireless
network. 802.11 Security covers the entire process of building
secure 802.11-based wireless networks, in particular, the 802.11b ("Wi-Fi")
specification. The authors provide detailed coverage of security issues unique
to wireless networking, such as Wireless Access Points (WAP), bandwidth
stealing, and the problematic Wired Equivalent Privacy component of 802.11.
You'll learn how to configure a wireless client and to set up a WAP using either
Linux or Free BSD. You'll also find thorough information on controlling network
access and encrypting client traffic. Beginning with an introduction to
802.11b in general, the book gives you a broad basis in theory and practice of
wireless security, dispelling some of the myths along the way. In doing so, they
provide you with the technical grounding required to think about how the rest of
the book applies to your specific needs and situations. Next, the book details
the technical setup instructions needed for both the Linux and FreeBSD operating
systems. Some of the topics covered include:

Station Security for Linux, FreeBSD, Open BSD, Mac OS X and Windows
Setting Up Access Point Security
Gateway Security, including building Gateways, firewall Rules, Auditing,
etc.
Authentication and Encryption
FreeBSD IPsec client and gateway configuration
Linux IPsec client and gateway configuration
802.1x authentication
802.11 Security is a book whose time has come. If you are a
network, security, or systems engineer, or anyone interested in deploying
802.11b-based systems, you'll want this book beside you every step of the
way.
