About the Author

Bill Pretty began his career in electronics in the early '80s with a small telecom start-up company that would eventually become a large multinational. He left that company to pursue a career in commercial aviation in Canada's north. From there, he joined the Ontario Center for Microelectronics, a provincially funded research and development center. After that, a career in the military as a civilian contractor at what was then called the Defense Research Establishment Ottawa. This began a career that was to span the next 25 years, and continues today.

Over the years, he has acquired extensive knowledge in the field of technical security and started his own company in 2010. That company is called William Pretty Security Inc. and provides support, in the form of research and development, to various law enforcement and private security agencies.

He has published and presented a number of white papers on the subject of technical security. He was also a guest presenter for a number of years at the Western Canada Technical Conference, a law enforcement-only conference held every year in western Canada. A selection of these papers is available for download from his website (http://www.williamprettysecurity.com/).

There a number of people I would like to thank, for without their support, this book would never have been completed. My good friends at Packt Publishing for having the patience and trust in me once again. To my partner in life, Donna, who never stopped believing in me. Last but not least, my good friends and fellow code warriors Willie the Mad Scott and Glen the flying Dutchman.
