Stefan Savage

Stefan Savage (* 1969 in Paris ) is an American computer scientist and professor at the University of California, San Diego (UCSD). He is an expert in network security, for example on the Internet.

Life

Savage grew up in New York City ( Manhattan ). He graduated from Carnegie Mellon University with a bachelor's degree in history and received his PhD in computer science from the University of Washington in 2002 with Thomas Edward Anderson (and Brian Bershad) (Protocol Design in an Uncooperative Internet). He then became a professor at UCSD. There he heads the Center for Network Systems (CNS).

In 2005 he was the founding director of the Collaborative Center for Internet Epidemiology and Defenses (CCIED, pronounced as seaside ) in San Diego (a joint project of UCSD and the International Computer Science Institute). Today (2016) he is co-director there. He also worked in various consulting roles, including being a consultant at Rendition Networks (acquired by OpsWare).

plant

In 2004 he developed automatic fingerprinting for computer worms, the basis for founding the company Netsift (later taken over by Cisco ), and analyzed the spread of various computer worms and methods of tracing their spread (as in the proposal for an IP router extension for this in the article Practical Network Support for IP Traceback from 2000). Savage also worked on distributed denial of service attacks in the network (for which he founded Asta Networks) and the detection of concurrency errors. In 1999 he pointed out weaknesses in the mechanism of congestion control of the TCP protocol, which worms could exploit.

In 2005, he and Ishwar Ramani developed the Syncscan algorithm, which allows you to switch between Wi-Fi stations more quickly. He also deals with electronic security issues relating to modern digitized automobiles (with his student Tadayoshi Kohno he succeeded in demonstrating that attackers could gain access to important operational functions from outside and thus point out security gaps and the potential for danger in general) and with the codes that were used in the emissions scandal .

He also examined the economy of Internet crime and malware, for example, in 2009 with Geoffrey Voelker and Vern Paxson, the economy of spam and infiltrated the botnet of spammers. They showed that these were still very profitable despite many anti-spam devices and they identified their commercial bank connections as the best point of attack for countermeasures.

Honors

In 2015 he received the ACM Prize in Computing (ACM Infosys Award) for innovative research on network security, data protection and reliability, which has taught us to see attacks and attackers as elements in a cohesive technological, social and economic system . In 2010 he became a Fellow of the Association for Computing Machinery (ACM). In 2014 he received the Mark Weiser Award and in 2017 he was awarded a MacArthur Fellowship .
