Acknowledgments

      This newly revised sixth edition that you hold in your hands is the culmination of more than a year of effort with the team at (ISC)² that I had the privilege of working with. This Common Book of Knowledge reflects the consensus across that team of the know-how that SSCPs need, on the job, to be part of maintaining the safety, security, integrity, and availability of the information systems we all depend upon.

      Where it achieves that objective, and provides you value in the years to come—is a testament to the generosity of everyone on that combined set of project teams in sharing their insights with me. (And where it fails to work well, or work at all, it's my own darned fault.) Countless hours on Zoom and Webex with subject-matter experts like Graham Thornburrow-Dobson, John Warsinksi, Maytal Brooks-Kempler, Laural Hargadon, and Fabio Cerullo sharpened my thinking and focused my writing more toward the operational aspects of cybersecurity and less on the theoretical. A special thank-you too goes out to Kaitlyn Langenbacher, the project owner for those updates at (ISC)², and all of the editors and proofreaders working with her; throughout all of that, the support, questions, and co-creativity they brought made this work a truly joint, collaborative one. I would also like to acknowledge my faculty teammates here at Embry-Riddle Aeronautical University for sharing their frank and candid views throughout many conversations on making this body of knowledge accessible and engaging in the classroom. The ideas and experiences of Drs. Aaron Glassman and Jason Clark have also profoundly affected my approach to what you see before you here in this book.

      Since this book needed to speak to troubleshooters, I drew on decades of teaching I'd received from many professionals in the military, in government, and in the private sector about the fine art and brute-force cybernetics of debugging networks, systems, highly secure communications systems, and all of the arcana of controlling space-based systems working many different missions. I've also drawn on years of working with small and medium but otherwise rather down-to-earth business IT systems and what it took to get them back into operations. Where that problem-solving focus comes through clearly and helps you shoot the troubles you have to deal with, I owe a great debt of thanks to those who let me learn how in real time.

Without the tireless support of the editorial team at Wiley/Sybex—especially Jim Minatel and Pete Gaughan—I think I'd still be struggling with unflowing the lessons and reflowing them into reference and troubleshooting memory-joggers.
