Security & Privacy
"Anomalous Payload-based Network Intrusion Detection" (2004) describes one of the first anomaly detection methods for identifying deviations indicative of a security breach.
The Sunlight tool uses robust statistical methods to trace user-tailored ads and recommendations back to user-supplied inputs like location, search terms and gender.
About
The security group works on a diverse set of security and privacy issues arising across the software/hardware stack.
The key research goal of the group is to design, develop, and deploy principled solutions for improving the security and privacy aspects of computer systems.
The group has a broad set of expertise ranging from systems security to designing privacy policies. It is a highly collaborative group and most of their students are co-advised by multiple faculty members.
