The 44th IPP Symposium
Protecting Facebook
Tao Stein, Facebook
Social networks are under attack all the time from phishers, fraudsters, and spammers. They aim to steal user information and expose users to spam. The attackers have vast resources at their disposal. They are well-funded, with full-time skilled labor, control over compromised and infected accounts, and access to global botnets. Protecting our users is a challenging adversarial problem with extreme scale and load requirements. Over the past few years we have built and deployed a system to protect our users and the social graph. The system performs real-time checks and classifications on every read and write action. The system also generates signals for use as feedback in classifiers and other components. This talk will describe specific threats to the graph, present the systems we have built, and outline current and future challenges.
Tao is an Engineer at Facebook. For the past 4 years he has been building systems to protect Facebook users. Prior to Facebook, Tao was a Researcher at Microsoft Research Asia in Beijing for several years where he built experimental operating systems. Tao received a PhD from Harvard in computer systems.
