Winner of the Best Book Bejtlich Read in 2010--

"Practical Lock Picking (PLP) is an awesome book. I don't provide physical testing services, but as a security professional familiar with Deviant's reputation I was curious to read PLP. Not only is PLP an incredible resource, it should also serve as a model text for others who want to write a good book. First, although the book is less than 250 pages, it is very reasonably priced. Second, Deviant wastes NO space. There is no filler material, background found in other readily available texts, reprinted Web site content, etc. Third, the writing is exceptionally clear and methodical, with extreme attention to detail and a master's approach to educating the reader. Finally, the diagrams, pictures, and figures are superb."--Richard Bejtlich, TaoSecurity
"No matter what your background is, if you want a new and fascinating insight into this world, I don't think any book will give you a better introduction to this field than this one."--Barry Wels, Founder and President, The open Organisation Of Lockpickers
"You have exhausted your budgets on the myriad of high tech cyber threats and finally have time to take a breath. Just as you settle in your chair to review the dashboard which shows the fruits of your tireless effort, an alert hits your phone. The voice on the phone cries out 'The servers are GONE!' This book will show you what happens when attackers decide to 'get physical."--Chris Nickerson, Lares Consulting
"The clear explanation and plentiful diagrams leave the reader with a clear idea of how lock mechanisms work, and the practice exercises that follow build on this knowledge to allow the reader to quickly progress before moving on to the simpler techniques, shimming and bumping...Overall the book does
