Scouting report
Wrote the 1989 paper cataloguing the security problems in TCP/IP — sequence-number prediction, source routing, DNS spoofing — years before anyone was exploiting them at scale. Co-authored Firewalls and Internet Security with Cheswick, co-invented encrypted key exchange, was a Usenet co-creator, and served as chief technologist at the FTC and on the Privacy and Civil Liberties Oversight Board.
Curator’s note
Published the attack list first and spent thirty years watching it come true.
