2023-03-22 CERIAS - 35 Years of Protecting the Internet

Recorded: 03/22/2023 CERIAS Security Seminar at Purdue University 35 Years of Protecting the Internet Steve Bellovin, Columbia For 35 years, the Internet has been bedeviled by attackers. For about as long, defenders have tried deploying various defenses;
these have often been of limited utility. We look back at what has happened, focusing on
the explicit or (more often) implicit assumptions behind the defenses, and why these
assumptions were or were not correct.Steven M. Bellovin is the Percy K. and Vida L. W.
Hudson Professor of Computer Science at Columbia University, member of the
Cybersecurity and Privacy Center of the university's Data Science Institute,
and an affiliate faculty member at Columbia Law School. Bellovin does research
on security and privacy and on related public policy issues. In his copious
spare professional time, he does some work on the history of cryptography.
He joined the faculty in 2005 after many years at Bell Labs and AT&T Labs Research,
where he was an AT&T Fellow. He received a BA degree from Columbia University,
and an MS and PhD in Computer Science from the University of North Carolina at
Chapel Hill. While a graduate student, he helped create Netnews; for this,
he and the other perpetrators were given the 1995 Usenix Lifetime Achievement
Award (The Flame). He has also received the 2007 NIST/NSA National Computer
Systems Security Award and has been elected to the Cybersecurity Hall of Fame. Bellovin has served as Chief Technologist of the Federal Trade Commission and as the Technology Scholar at the Privacy and Civil Liberties Oversight Board. He is a member of the National Academy of Engineering and has served on the Computer Science and Telecommunications Board of the National Academies of Sciences, Engineering, and Medicine. In the past, he has been a member of the Department of Homeland Security's Science and Technology Advisory Committee, and the Technical Guidelines Development Committee of the Election Assistance Commission.Bellovin is the author of Thinking Security and the co-author of Firewalls and Internet Security: Repelling the Wily Hacker, and holds a number of patents on cryptographic and network protocols. He has served on many National Research Council study committees, including those on information systems trustworthiness, the privacy implications of authentication technologies, and cybersecurity research needs; he was also a member of the information technology subcommittee of an NRC study group on science versus terrorism. He was a member of the Internet Architecture Board from 1996-2002; he was co-director of the Security Area of the IETF from 2002 through 2004.More details may be found at www.cs.columbia.edu/~smb/informal-bio.html.
