Writing a technical book is a very difficult task and can take a very long time. Of the five books I have contributed to, written, or have in development, I can say that each has been the ultimate challenge to make interesting, appropriate, and suitable for its audience.

This book would not have been possible without my Editor, Ms. Pam Chester, and Senior Development Editor, Mr. Gregory Chalson, whose tireless efforts have helped me through the difficult process of publishing a book.

I can also say that this book would not have been possible in any way without Mr. Nabil el Khazen and Mr. Adel Mardelli, my partners in the security consulting firm Protection Partners International. Without their cheerful support and dedication to excellence, I would not have the ability to spend the time each day necessary to hunker down and focus on each chapter.

I would also like to thank Mr. Adel Mardelli; my protégé, Ms. Rima Ghanem; and Ms. Hala Abou Yazbeck who have all provided valuable support toward the completion of this book. Additionally, I am grateful to my wife, Ms. Cynthia Kamalo-Norman, for her encouragement.

But most of all, I would like to thank you, the reader, for continuing to buy my books and for your e-mails. I am always happy to answer your questions. I am truly grateful to each of you for your continued support.
