This title shows readers how to secure 802.11 based wireless networks. Detailed coverage includes security issues unique to wireless networking, such as Wireless Access Points (WAP), bandwidth stealing, and the problematic Wired Equivalent Privacy component of 802.11.

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.
