I would like to thank my family foremost, my mother and father, Lynda and Billy Bayles, for supporting me and giving me the skills that have allowed me to excel in work and life. My wife Jennifer is a never-ending source of comfort and strength that backs me up whenever I need it, even if I don't know it. I can't describe the joy and love she gives me every single day. The people who have helped me learn my craft have been numerous, and I don't have time to list them all. Basically all of you from SHSU Computer Services, Falcon Technologies, SAIC, and Sentigy know who you are and how much you have helped me, my most sincere thanks. I would also like to thank Chris, Ed, Johnny, and James for their help with this book; their experience and support has been invaluable and this book would not have been complete without them. Final thanks go to Jaime and Andrew, along with the entire staff at Syngress Publishing, for putting up with my quirks and giving me the opportunity to share my thoughts with you.
