NIST SP 800-97 February 2007 Printed in COLOR A wireless local area network (WLAN) enables access to computing resources for devices that are not physically connected to a network. WLANs typically operate over a fairly limited range, such as an office building or building campus, and usually are implemented as extensions to existing wired local area networks to enhance user mobility. This guide seeks to assist organizations in better understanding the most commonly used family of standards for WLANs—Institute of Electrical and Electronics Engineers (IEEE) 802.11—focusing on the security enhancements introduced in the IEEE 802.11i amendment. In particular, this guide explains the security features and provides specific recommendations to ensure the security of the operating environment. Why buy a book you can download for free? First you gotta find it and make sure it’s the latest version (not always easy). Then you gotta print it using a network printer you share with 100 other people – and its outta paper – and the toner is low (take out the toner cartridge, shake it, then put it back). If it’s just 10 pages, no problem, but if it’s a 250-page book, you will need to punch 3 holes in all those pages and put it in a 3-ring binder. Takes at least an hour. An engineer that’s paid $75 an hour has to do this himself (who has assistant’s anymore?). If you are paid more than $10 an hour and use an ink jet printer, buying this book will save you money. It’s much more cost-effective to just order the latest version from Amazon.com This book is published by 4th Watch Books and includes copyright material.
