Ian D. Foster

Security researcher · Security engineer

I work on security engineering and research, focusing on Internet infrastructure, including DNS, TLS and certificates, and ISP networks, as well as embedded and automotive systems.

I did my M.S. research in the Systems and Networking and Security and Cryptography groups at UC San Diego with Stefan Savage, Geoff Voelker, and Kirill Levchenko, and I continue to collaborate with researchers there. I’m a member of the Center for Evidence-based Security Research, the Center for Networked Systems, and the Center for Automotive Embedded Systems Security.

As an undergraduate at UCSD I founded Eve, the student information security club. I also run DNS Coffee, a long-running archive of DNS zone data used for security and academic research.
