Scouting report
Co-wrote the 1994 book that taught the industry what a firewall was and how to reason about a perimeter. “An Evening with Berferd” documented him feeding a live intruder a fake environment for months and writing down everything, which is the honeypot genre’s founding text. Later ran the Internet Mapping Project at Bell Labs.
Curator’s note
Invented the practice of watching the attacker instead of just shutting the door.
