Reference excerpt

Steven M. Bellovin is a researcher on computer networking and security who has been a professor in the computer science department at Columbia University since 2005. Previously, Bellovin was a fellow at AT&T Labs Research in Florham Park, New Jersey. In September 2012, Bellovin was appointed chief technologist for the United States Federal Trade Commission, replacing Edward W. Felten, who returned to Princeton University. He served in this position from September 2012 to August 2013. In February 2016, Bellovin became the first technology scholar for the Privacy and Civil Liberties Oversight Board.

Career Bellovin received a BA degree from Columbia University, and an MS and PhD in computer science from the University of North Carolina at Chapel Hill. As a graduate student, Bellovin was one of the originators of USENET. He later suggested that Gene Spafford should create the Phage mailing list as a response to the Morris Worm. Bellovin and Michael Merritt invented the encrypted key exchange password-authenticated key agreement methods. He was also responsible for the discovery that one-time pads were invented in 1882, not 1917, as previously believed. Bellovin has been active in the IETF. He was a member of the Internet Architecture Board from 1996 to 2002. Bellovin later was security area codirector, and a member of the Internet Engineering Steering Group (IESG) from 2002 to 2004. He identified some key security weaknesses in the Domain Name System; this and other weaknesses eventually led to the development of DNSSEC. He received 2007 National Computer Systems Security Award by the National Institute of Standards and Technology (NIST) and the National Security Agency (NSA). In 2001, he was elected as a member into the National Academy of Engineering for his contributions to network applications and security. In 2015, Bellovin was part of a team of proponents that included Matt Blaze, J. Alex Halderman, Nadia Heninger, and Andrea M. Matwyshyn who successfully proposed a security research exemption to Section 1201 of the Digital Millennium Copyright Act. Bellovin is an active NetBSD user and a NetBSD developer focusing on architectural, operational, and security issues. He is a two-time recipient of the Usenix Lifetime Achievement Award. In 1995 he and two others received the award “for their work in creating USENET.”. In 2023, he and two others received the award “for a profound and lasting impact on Computer Science, Computer Security, Law, and Public Policy through their groundbreaking research, their influential publications, and their dedication to advancing knowledge that informs public policy.”.

Selected publications Bellovin is the author and co-author of several books, RFCs and technical papers, including:

Firewalls and Internet Security: Repelling the Wily Hacker ISBN 0-201-63357-4 (with W. Cheswick) – one of the first books on internet security. Firewalls and Internet Security: Repelling the Wily Hacker 2nd edition ISBN 0-201-63466-X (with Cheswick and Aviel D. Rubin) Thinking Security: Stopping Next Year's Hackers (2015) ISBN 978-0134277547 RFC 1579 Firewall-Friendly FTP RFC 1675 Security Concerns for IPng RFC 1681 On Many Addresses per Host RFC 1948 Defending Against Sequence Number Attacks RFC 3514 The Security Flag in the IPv4 Header (April Fools' Day RFC) RFC 3554 On the Use of Stream Control Transmission Protocol (SCTP) with IPsec (with J. Ioannidis, A. Keromytis, R. Stewart.) RFC 3631 Security Mechanisms for the Internet (with J. Schiller, Ed., C. Kaufman) RFC 4107 Guidelines for Cryptographic Key Management (with R. Housley) As of October 21, 2020, his publications have been cited 19,578 times, and he has an h-index of 59.

Worked examples

Example 1 — a first encounter with Steven M. Bellovin

Start with the simplest possible case. Write down what Steven M. Bellovin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Steven M. Bellovin before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Steven M. Bellovin ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Steven M. Bellovin

In research: Steven M. Bellovin appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Steven M. Bellovin in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Steven M. Bellovin is common in secondary-school and first-year university syllabi. It links to neighbouring topics American chief technology officers, American computer security academics, Columbia College, Columbia University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Steven M. Bellovin outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
