SACMAT

It is our great pleasure to welcome you to the 17th ACM Symposium on Access Control Models and Technologies (SACMAT 2012). This year's symposium continues its tradition of being the premier forum for presentation of research results on leading edge issues of access control, including models, systems, applications, and theory.

73 papers have been submitted from a variety of countries around the world. Submissions were anonymous; each paper has been reviewed by at least three reviewers who are experts in the field. Extensive online discussions took place to make the selections for the symposium. The program committee finally accepted 19 papers that cover a variety of topics, including RBAC, role mining, privacy, access control policies and models, and access control for mobile devices. The program again contains a demo session with five demos covering topics such as risk aggregation for RBAC, assured information sharing, policy enforcement and access control for business processes. In addition the program includes a panel on Emerging Trends around Big Data Analytics and Security, and keynote talks by Ruby Lee and Ravi Sandhu. We hope that these proceedings will serve as a valuable reference for security researchers and developers.
