Book Description
Finally--a single volume guide to really effective security for both voice and data wireless networks!
More and more data and voice communications are going via wireless at some point between the sender and intended recipient. As a result, truly "bulletproof" wireless security is now more than a desirable feature--instead, it's a necessity to protect essential personal and business data from hackers and eavesdroppers.

In this handy reference, Praphul Chandra gives you the conceptual and practical tools every RF, wireless, and network engineer needs for high-security wireless applications.
Inside this book youll find coverage of these essential topics:

+ Cryptographic protocols used in wireless networks.
+ Key-based protocols, including key exchange and authentication techniques
+ Various types of wireless network attacks, including reflection, session hijacks, and Fluhrer-Mantin-Shamir (FMS) attacks.
+ Encryption/decryption standards and methods.
+ Multi-layered security architectures.
+ Secure sockets layer (SSL) and transport layer security (TLS) protocols.
+ Cellular telephone network architectures and their vulnerabilities.
+ Modulation techniques, such as direct-sequence spread spectrum (DSSS) and orthogonal frequency division multiplexing (OFDM).

And youll also find coverage on such cutting-edge topics as security techniques for ad hoc networks and protecting Bluetooth networks. If youre serious about wireless security, then this title belongs on your reference bookshelf!

» Designing A Wireless Network

Wireless network design presents the IT professional with unique obstacles. Your network requires the seamless and secure distribution of information, in spite of competing communication protocols, incompatible hardware platforms, and narrow bandwidths. This book is an introduction to developing efficient means of wireless transport in order to fully leverage wireless technologies.

Certain cities--Singapore is one example--have begun to outfit gathering places like airport lounges and downtown coffee shops as "hot spots" that are served by wireless Internet antennas. It's possible for anyone with an IEEE 802.11b card in a laptop to sit down in one and have Internet access immediately. The author of Building Wireless Community Networks, Rob Flickenger, thinks this is a great idea. He's written this small, thin volume to explain to readers why wireless networking is a community asset, and to bring them up to speed on the technologies available for creating wireless hot spots. Community here means a collection of people, as in a town or neighborhood.

Wireless networking protocols are complicated, but IEEE 802.11b and the products that have sprung up around it (like Apple's AirPort and similar offerings from Lucent Technologies and Cisco Systems) are pretty easy to set up and integrate into a network. Flickenger's treatment deals with these admirably but places more emphasis on configuring operating systems (notably Linux) to work as wireless gateways for transient users. The really fun reading has to do with custom antennas, though. Flickenger explains--no kidding--how to convert a Pringles potato-chip can into an antenna for wireless networking and goes into detail on how to work around the challenges posed by topography and human-made obstacles. This is a smart book about one of the most exciting frontiers in computer networking. --David Wall

» Wi-Foo

Because Foo! Ok, I'll admit that's pretty bad. But seriously, it's a take on martial arts like Kung-Fu. Many people's take on Kung-Fu is you learn it to protect yourself. This is Wireless meets Kung-Fu. Here you learn how to protect a wireless network.

It's a very good wireless security book. The authors also have a website http://www.wi-foo.com, which has many of the tools used in the book.

There are multiple white papers and books on wireless security (only two years ago you would hardly find any). Many of them, including this book, are centered around 802.11 standards. Most explain the in-built security features of 802.11 protocols, future 802.11 security standards development and requirements, list (and sometimes describe in details) known security weaknesses of 802.11 networks and the countermeasures that a wireless network manager or system administrator can take to reduce the risks presented by these flaws. However all books (except this one) do not describe how the "hackers" can successfully attack wireless networks and how system administrators can detect and defeat these attacks - step-by-step, as the actual attack takes place.

We believe that the market needs, above all else a hands-on, down-to-earth source on penetration testing of wireless networks. Such a source should come "from the field" and have to be based on the practical experience of penetrating a great deal of client and testing wireless nets - an experience that many in the underground and few in the information security community possess. As a core of the Arhont wireless security auditing team, the authors perform wireless penetration testing on nearly a daily basis and we hope that our experience will give you a good jump-start on practical wireless security assessment and further network hardening.

Fully addressing the most critical WLAN and Wireless IP issues in the industry today, this practical new resource focuses on the areas of security, mobility, and QoS improvement. The book gives you a solid understanding of IEEE 802.11 standards and presents solutions discussed by the IEEE 802.11 standardization committee, including those that can be provided at the IP layer. Moreover, the book provides guidance on deployment, insights on interworking with 3G mobile communications systems, and discussions on the market and business aspects of WLANS. From basic WLAN and Wireless IP concepts and the current status of IEEE 802.11, to WLAN deployment and integration with GPRS and UMTS and the future role of WLAN in beyond 3G and 4G systems, this authoritative reference presents a thorough overview of the key issues and possible solutions for WLANs from layer-1 to layer-3 and higher protocol layers, wherever necessary. The book is generously supported with over 120 illustrations.
