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.
