Security Seminar in Loria : Deepak Garg (MPI Saarbrücken)

décembre 5 @ 13:30 - 15:00

The talk will take place on the December 5th in room A008 at 13:30.
Abstract :
Many database-backed systems store confidential data that is accessed on behalf of users with different privileges. Policies governing access are often fine-grained, being specific to users, time, accessed columns and rows, values in the database (e.g., user roles), and operators used in queries (e.g., aggregators, group by, and join). Today, applications are often relied upon to issue policy compliant queries or filter the results of non-compliant queries, which is vulnerable to application errors. Qapla provides an alternate approach to policy enforcement that neither depends on application correctness, nor on specialized database support. In Qapla, policies are specific to rows and columns and may additionally refer to the querier’s identity and time. They are specified in SQL, and stored in the database itself. The talk will cover the design of Qapla, a prototype implementation and its application to the HotCRP conference management system.
