802.11 Security.doc

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.

Putting It All Together 199 Colophon 203 "802.11 Security provides practical solutions for all major components of an 802.11 network. Station security configurations are documented for many operating systems, including Linux, FreeBSD, OpenBSD, Mac OS X, and Windows. Real world networks contain many different operating systems, and this book will give you the tools to secure whatever is thrown your way." "802.11 Security is essential for anyone deploying a wireless network. It provides the board background and specific examples needed to secure your network and your valuable data."--BOOK JACKET Beginning with an introduction to 802.11b in general, 802.11 Security 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. 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. Focusing on wireless LANs in general and 802.11-based networks in particular, Potter (VeriSign) and Fleck (Secure Software) outline strategies and implementations for deploying a secure wireless network. They explain how the 802.11 protocols work and how an attacker will attempt to exploit weak spots within a network, and suggest methods for locking down a wireless client machine and securely configuring a wireless access point. Annotation : 2004 Book News, Inc., Portland, OR (booknews.com) Discusses the fundamentals of wireless security and of the popular wireless LAN protocol 802.11, covering topics including station security configurations, network weaknesses, access points, and client security.
