RANDLab is a research group at the University of California, led by Prof. Ram Sundara Raman, advancing the security, privacy, and reliability of networks and the data that flows through them. We tackle real-world Internet challenges, developing empirical methods, systems, and frameworks to detect, measure, and defend against large-scale attacks on users’ security and privacy.
