Cisco Wireless LAN Security is an in-depth guide to wireless LAN technology and security, introducing the key aspects of 802.11 security by illustrating major wireless LAN (WLAN) standards that can protect the entire network. Because a WLAN is less effective as an isolated piece of the network, this book emphasizes how to effectively integrate WLAN devices into the wired network while maintaining maximum security.

Cisco Wireless LAN Security covers the spectrum of WLAN security, including protocols and specifications, vulnerabilities and threats, and, especially, deployment patterns and design guidelines. With a unique combination of theory and practice, this book addresses fundamental wireless concepts, such as WEP, and innovations, such as EAP, switching, and management. Each chapter includes detailed illustrations, checklists, design templates, and other resources. You will also find generic wireless deployment patterns based on real-world customer installations and functional examples of architecture, design, and best practices.

Whether you currently design, configure, implement, and maintain WLANs or simply want to explore wireless security issues, Cisco Wireless LAN Security has everything you need to understand how to create a seamlessly secure, impenetrable 802.11 network.

This book is part of the Networking Technology Series from Cisco Press¿ which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

5.0 out of 5 stars Excellent Resource for Any WLAN Administrators, June 19, 2006

By	Tony Bradley "s3kur3.com" (Houston, TX) - See all my reviews

The four authors of Cisco Wireless LAN Security do an excellent job of striking a balance between writing concise enough that the book is not overwhelming, but detailed enough for the reader to truly understand the subject matter. Not an easy task.

The book is titled Cisco Wireless LAN Security, which might actually make some people shy away from it, but the Cisco part is a bit of a misnomer. Some of the information and examples are Cisco-centric, but the majority of the information in the book is vendor-neutral and should be understood and applied on just about any wireless network.

The beginning chapters provide an excellent framework for those new to wireless LAN technology, but it quickly moves beyond that to much deeper and more complex subjects within wireless LAN security.

The discussion of wireless vulnerabilities and on wireless security techniques helps you gain an understanding that you can take away from the book and apply to your unique situation. The configuration samples and examples throughout the book are excellent.

I don't recommend that someone new to wireless networks pick this up, but anyone tasked with protecting or securing a wireless LAN should definitely use this book as a resource.

5.0 out of 5 stars Good treatment of the topic on Wireless LAN Security, July 20, 2005

By	Trevor Chandler "Trevor" (Houston, TX USA) - See all my reviews

The title is definitely in alignment with the content. A basic-to-intermediate discussion of security, as it applies to wireless LANs, is presented in this book. When I completed the book, I certainly had a much better understanding of wireless LAN security fundamentals - both generically and with a Cisco slant. The book has contributions from 4 persons, which may explain the healthy perspective given to the subject of wireless LAN security.

I know the number of chapters of a book can't always tell much of the story, but in the case of the 13 chapters contained in this book - spread out over almost 400 pages - I immediately felt that no single chapter would contain an amount of information that may be overwhelming as far as being able to retain my focus. The 2 final chapters comprised the greatest number of pages for any single chapter, and rightfully so. It would have been a compromise of the completion of the overall material to have limited the number of pages involving configuration examples and deployment scenarios.

I really appreciated chapter 2. This chapter was titled "Basic Security Mechanics and Mechanisms", and the content was just as the title suggested. The subject matter discussed security without any connection to wireless LANs. With "Security" being a complete topic all by itself, it was beneficial to have a little introduction to some generic security fundamentals before blending this topic with wireless networking. If the subject of computer/network security is not your forte, then you'll be served well with this brief exposure.

Chapters 3 and 4 were a welcomed addition because they provided a "warm-up" to wireless networking. The authors, in my opinion, did a very good job in not assuming that the reader would be a seasoned veteran of wireless networking. With chapters 2, 3 and 4 leading the way, the groundwork was set for a solid comprehension for the remainder of the book.

So, it is in chapter 5 -- "WLAN Basic Authentication and Privacy Methods" -- where the discussion of security for wireless LANs really begins. Once again, the title of the chapter is in sync with the content. What's provided is some light exposure to security methods. The information in the previous chapters really help to digest this chapter's material. This chapter is one of the "key" chapters in the book's presentation of wireless LAN security; the foundation to the discussion of wireless LAN security begins here.

The remaining chapters up to chapter 11 contained more in-depth discussion of security in the wireless LAN. I was pleased to see a discussion on the Wireless Domain Services (WDS), Wireless LAN Solution Engine, and Cisco Structured Wireless Aware Network (SWAN). While there's plenty of information at Cisco's website regarding these mechanisms, including the information in the context of the book content enhanced my understanding.

I don't believe this is a book that is intended to prepare for any Cisco-related certification; not that that was suggested anywhere to begin with. However, the reason for my comment is because there are none of the traditional questions at the end of each chapter to test chapter comprehension. So, if you want to test your understanding or memory, you'll have to create your own questions as your read through each chapter.

There will be a number of terms that may be unfamiliar to some readers, so I'll encourage you to note those as you read each chapter. The book contains no glossary for you to reference terms -- all nice and neat, in alphabetical order.

The book is for someone with at least a Cisco Certified Network Administrator (CCCNA)-level of knowledge. Certainly if the reader has a fair understanding of wireless networking, the focus can be exclusively placed on wireless LAN security. I would not recommend this book as a first-read to someone who doesn't have an understanding of wireless networking -- unless they're going to read only chapters 3 and 4. Again, chapters 3 and 4 are very good for a first exposure to wireless LAN theory.

Using a rating scale of 1 to 5 (with 1 being the worst, and 5 being the best) I'd give the book a rating of 5. Even with the fast evolution of wireless networking technology, and wireless standards being in almost a constant state of flux, I can see how I'd still be able to refer to this book for many months to come.

4.0 out of 5 stars how to bolt down your wireless LAN, May 29, 2006

By	W Boudville (Terra, Sol 3) - See all my reviews (TOP 10 REVIEWER)    (REAL NAME)

The title explicitly says Cisco, and indeed there is a lot of material enclosed that is specific to how Cisco implements its wireless routers. But you could plausibly also use this book as a good guideline to general purpose wireless security.

The authors have gone to some length to explain the general principles of 802.11*. In and of itself, this will be useful to some readers, for 802.11 is now a huge set of complex standards. With the official documentation being quite turgid prose, though necessary of course. For clarity, this book is a good and far more understandable alternative.

The text also goes into associated topics, like the encryption protocols associated with 802.11. Plus, and this is important, it describes third party, often open source, tools that can be used to sniff for insecure networks. Tools like Kismet or Wellenreiter, where the latter is meant for wardriving. One of the first things you should do is download and use one of these tools [or even several of them] against your wireless net, if it is already running. Better that you discover any weaknesses in it, than others do so.
