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] 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.
