Jonathan has been commissioned to teach NCIS investigators how to use Snort, performed packet analysis from a facility more than 2000 feet underground, and chartered and trained the CIRT for one of the largest U.S. Civilian Federal agencies. He holds several industry certifications including the CISSP, GSEC, GCIA, and GCIH certifications, and is a member of the GIAC Advisory Board.
Jonathan is the co-author of "Network Forensics: Tracking Hackers Through Cyberspace" (Prentice Hall, 2012)---the first comprehensive textbook on the subject. He is also the co-author (with Shon Harris) of the CISSP Practice Exams, now in it's 5th Edition (McGraw-Hill, 2018). A former combat medic, Jonathan still spends some of his time practicing a different kind of emergency response, volunteering and teaching for both the National Ski Patrol and the American Red Cross.
