Acknowledgments

I would like to thank my lovely wife Nicoleta and my daughters, Anna and Disa, for supporting me and putting up with me for the past three years. I know this was a long process, and I know you might have not liked it at times, but now that is done I hope that people will find it educational and then all of it was worth it.

I want to thank Bob Elliott for believing in me even when I didn’t. I want to thank Jennifer Lynn and Rosemarie Graham for their help in making this book happen. I would like to thank Anders Bratland for lending his expertise and making sure that this book is technologically accurate. I would like to thank my co-authors Gerry O’Brien, Rod Stephens, and Vince Varallo for their hard work and devotion.

I would also like to thank Sergiu Damian for his help reviewing my chapters, Catalin Pop for helping me with his expertise on encryption, and Susan Ibach and Christopher Harrison for recommending me as author.
