Checking Risky Events Is Enough for Local Policies
Abstract. An extension of the λ-calculus is proposed to study historybased access control. It allows for parametrized security policies with a possibly nested, local scope. To govern the rich interplay between local policies, we propose a combination of static analysis and dynamic checking. A type and effect system extracts from programs a correct approximation to the histories obtainable at run-time. A further static analysis over these approximations determines how to instrument code so to enforce the desired security constraints. The execution monitor, based on finite-state automata, runs efficiently the instrumented code.
