I was recently given the book Wi-Foo, The Secrets of Wireless Hacking as a present for my birthday, and I have been reading it extensively for the past few days. I have been involved with wireless security for a few years now, giving security talks to members of my community and helping out friends and family stay secure while enjoying the wonderful advantages of wireless computing. Over the past couple of years, I have slowly built up a small reference library of books related to wireless technologies and security. I even got involved in a small antenna building hobby which enabled me to better understand some of the ways RF works.
Upon reading the first few chapters of this book, I realized that this tome was different. The information contained within its pages wasn’t a re-hashed compendium of information that could potentially be gathered across the internet and spoon-fed to the reader. In this case, the author brings us along as the many vulnerabilities of wireless computing are brought forward, how those vulnerabilities are exploited by nefarious individuals, and the ever-expanding variety of tools availble to assist in exploiting these vulnerabilities are described.
Don’t get the wrong idea here; this isn’t the run-of-the-mill Howto put together from various information sources freely available on the internet. The authors take painstaking efforts to explain how the various wireless encryption/security options, such as WEP, WPA, LEAP, TKIP, PSK, etc, work, and how they can be defeated. The tools are not only defined, but described in relation to how they leverage and exploit the vulnerabilities and why they work.
As you can imagine, I’m definitely going to be reading this book from cover to cover. The information within is fresh and very comprehensive. While extensive in its depth, I still believe that this is an ideal book for anyone, from beginner to expert, who has a desire to better understand wireless computing technologies, its advantages and disadvantages, and how to protect oneself from evil-doers, out to take advantage of the stealth that wireless provides.
