Biography

Afek was born in Haifa in 1952 to Holocaust survivor parents (Miriam and Menachem Pinkhof) who were among the founders of the Dutch underground (Westerweel Group) who saved over 300 Jewish youths during the Holocaust until they were captured by the Nazis. They both received the Jewish holocaust rescuer Medal . . Afek studied at the Hebrew Reali School in Haifa, and in 1970 enlisted in the IDF where he served as a fighter in an special elite operations unit (Sayeret Matkal) , a service that was extended due to the Yom Kippur War. In 1974 he was on the teams that founded the Shaldag special operations unit before returning to serve in the elite unit in reserve service. In 1978 he earned a bachelor's degree in electrical engineering at the Technion. In 1978-1980 he worked as an IDF civilian engineer, developing the avionics unit and autopilot of the first successful UAV manufactured by the Israeli Air Force. In 1980-1985 he earned an MSc and PhD respectively, in computer science from the University of California, Los Angeles (UCLA). From 1985 to 1988, he worked as a researcher at AT&T's Bell Laboratories. In 1988 he joined the faculty in the Department of Computer Science at Tel Aviv University, where he is currently a full professor . He also served as head of the School of Computer Science from 2014 to 2016. Over the years he has been invited as a guest and consultant for various time periods to [AT&T|at&t] and Microsoft research labs, and to UCLA, and spent one-semester sabbatical at Simon Institute, Berkeley .

In 2001 Afek was the lead founder of Riverhead Networks, the only company that at the time successfully provided a mitigation system to the Distributed Denial of Service attacks on the Internet . The Riverhead Guard , the flag product, protected tens of thousands of sites (including some from fortune-5, and many from fortune-500), keeping them up and running despite massive multi Gbps attacks over long periods of time. Riverhead was acquired by Cisco Systems in 2004, after which Afek remained a CTO and director in Cisco Israel until May of 2009. In 204-2009 Afek lead the creation of ISPs managed security service with AT&T and many of the world tier-1 and tier-2 ISPs.
