To my adoring wife, Cathy: Building a life and a family together has been more wonderful than I could have ever imagined.

Special thanks go to the information security team at the University of Notre Dame, who provided hours of interesting conversation and debate on security issues that inspired and informed much of the material in this book.
I would like to thank the team at Wiley who provided invaluable assistance throughout the book development process. I also owe a debt of gratitude to my literary agent, Carole Jelen of Waterside Productions. My coauthors, James Michael Stewart and Darril Gibson, were great collaborators. David Seidl, our diligent and knowledgeable technical editor, provided valuable insight as we brought this edition to press.
I’d also like to thank the many people who participated in the production of this book but whom I never had the chance to meet: the graphics team, the production staff, and all of those involved in bringing this book to press.
Thanks to Carol Long and Carole Jelen for helping get this update in place before (ISC)2 released the objectives. This helped us get a head start on this new edition and we appreciate your efforts. It’s been a pleasure working with talented people like James Michael Stewart and Mike Chapple. Thanks to both of you for all your work and collaborative efforts on this project. The technical editor, Dave Seidl, provided us with some outstanding feedback and this book is better because of his efforts. Thanks again, David. Last, thanks to the team at Sybex (including project managers, editors, and graphics artists) for all the work you did helping us get this book to print.
