Static Verification of Code Access Security Policy Compliance of .NET Applications

By: Jan Smans, Bart Jacobs, Frank Piessens

Abstract

In this paper, we propose formal component and method contracts for stack inspection-based sandboxing, and we show that formal verification of these contracts is feasible with state-of-the-art program verification tools. Our contracts are significantly more expressive than existing type systems for stack inspection-based sandboxing. We describe our solution in the context of the sandboxing mechanism in the .NET Framework, called Code Access Security. Our system relies on the Spec# programming language and its accompanying static verification tool.
