Held recently in Salt Lake City, the ACM Conference on Computer and Communications Security (CCS) is a premier peer-reviewed publication venue and forum that brings together information security researchers, practitioners, developers, and users from all over the world to explore cutting-edge ideas and results. In a testament to Brown’s tradition of research excellence and leadership in computer security for two and a half decades, members of the Brown CS community co-authored fourteen of the conference’s accepted papers in a broad range of areas, served as seven members of its Program Committee, and were recognized as one of its Distinguished Reviewers.
