Book Description

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.

3.0 out of 5 stars Wonderful book, title should mention Unix. Sept. 29 2003
802.11 Security is another fine O'Reilly book, it is very nicely written and laid out and the message is crystal clear.
The reason I gave it three stars was that the book is heavily biased towards Linux, Free BSD, and Open BSD and the title does not reflect the bias. That is not a bad thing, I found the unix information wonderful, but if you are ordering 802.11 Security over the web, you might easily miss the unix emphasis and end up with a book that doesn't meet your needs.

5.0 out of 5 stars As secure as it can be July 10 2003
You've got one, I've got one, we've all got one. Wired networks have become so passe` now that wireless networks are everywhere. The one characteristic of most wireless networks is the lack of security. Enter O'Reilly's 802.11 Security.
Potter and Fleck have written this little book as a no-nonsense guide to understanding the problem of wireless networking security. They also do an excellent job demonstrating how to implement solutions that are quick, simple and actually work.
Overall, I would have to say that this book is a gold mine for anyone running an 802.11 network. It has helped me figure out how to implement wireless networking at home thus minimizing security risks. As usual the book is very easy reading and it's written in a very easy-going style giving the necessary background before launching into any detailed discussions. I would highly recommend this book to anyone considering or using a wireless network.
Even though given enough time my wireless network could be sniffed out, I feel much better having a better understanding of how important securing my wireless network is and knowing that I've done what I can to prevent unauthorized use.

2.0 out of 5 stars No worth the money---DON'T WASTE IT on this book. June 10 2003
I did the smart thing and got this book on inter-library loan BEFORE making a decision whether to purchase it. I noted that the book was only 176 pages long. Word to the wise: If a book on tech stuff is that short, be suspicious of the content. When a tech book is small like this one is, there usually is no "there" there. And when I see that a book this short is cover priced at almost $(Amamzon edited out the cover price, so look for it elsewhere) USD, all kinds of red warning lights begin to flash in my head. Glad I didn't waste the money!
In a word this book is "cursory." I was looking for solutions for a good cross-platform security solution for my wireless LAN. All this book gave me were other places to go for information. For instance, there is a section on IPSec VPN that is a grand total of seven pages long, which has good plans for how to use FreeBSD or Linux servers, but then also refers you to a website for more information. There are a bunch of website references scattered throughout the whole of the book in a "look here for more information" way. If I wanted to reference the web for information, I'd use Google for FREE and not spend almost (cover price) to have someone else tell me where to look.
The author states in the beginning of the book that if you are familiar with FreeBSD and Linux and want to use these for wireless security it's a good book to read. Well, speaking from an admin's standpoint, and having compiled several FreeBSD kernels and setup several Linux boxes, this book is FAR below my experience level. If you are an admin of WinTel boxes, this book is not for you. If you are a Macintosh admin (which I also am), don't bother with this book either.

4.0 out of 5 stars David Weeks MyMac.com Book Review Feb. 11 2003
Warning Will Robinson! This small book on 802.11b wireless security (167 pages not including the comprehensive index) is not for the faint of heart. To take full advantage of the copious amount of detail that Potter and Fleck provide, you need a good working knowledge of networking, and familiarity with either the Linux, FreeBSD, or OpenBSD operating systems.
802.11 Security is aimed at people who need to configure and administer secure 802.11b wireless (popularly named Airport or WiFi) networks. 802.11 Security is NOT targeted at the casual home computer user who merely wants to keep others from poaching their wireless connection. Those users are best served by Adam Engst's and Glenn Fleishman's Wireless Internet Starter Kit.
However, if you have any interest in comprehensive and detailed knowledge of how 802.11b security works from the network administrator's viewpoint, 802.11 Security is the book for you. Potter and Fleck have years of experience with Unix security issues, and have several papers on the subject to their credit.
After setting the stage with a good discussion of the many problems with wireless security, the authors outline some of the more common types of attacks on wireless networks. Why? Their point is that understanding the nature of the "Man-in-the-middle" attack (for example) is important for knowing how to prevent it. This point shows that 802.11 Security is more than just a "cookbook" manual. It provides the "why" as well as the "how."
The bulk of the book covers how to configure FreeBSD, Linux, and OpenBSD clients, gateways, and access points (base stations for us Apple types). Plenty of examples are provided.

I don't agree with the negative reviews above. The book doesn't pretend to be a reference of 802.11 protocols at all. Read more
