This book owes a big thank you to the awesome developers of the Wireshark suite, as well as the developers of Metasploit, Lua, Docker, Python, and all the other open-source developers who make amazing technology accessible. Thanks also to the people at Wiley for putting up with me, especially John Sleeva and Jim Minatel, and to Rob Shimonski, the fantastic technical editor who helped keep the book correct and useful. Special thanks go to my co-author Jeff Parker for taking on the challenge of writing this book. He was a blast to work with and is owed immense credit for helping make this book possible.

I would also like to thank Jan Kadijk, John Heasman, Jeremy Powell, Tony Cargile, Adam Matthews, Shaun Jones, and Connor Kennedy for contributing ideas and support.

Kudos to the Wiley team, including Jim Minatel, John Sleeva, and Kim Heusel, for their dedication to carry this book to the finish line. Big thanks to Rob Shimonski, the technical editor, who performed with great patience to ensure we left no gaps or confusion.

To Jessey, the book's visionary and the W4SP Lab guru, I thank you for being ever gracious and collaborative. All your effort concludes with a book and online resources that we can both be proud of.

To Carole Jelen, my literary agent in sunny southern California, all opportunities start with you. You are an endless provider of growth and have my deep gratitude. Thanks, Carole!

The biggest thanks go to my wife and my best friend. I'm grateful for her patience and support. To our two kids, Dad is back and ready to play (and research for the next book—wink, wink).
