Abstract Access control mechanisms control which subjects (such as users or processes) have access to which resources. To facilitate managing access control, policy authors increasingly write access control policies in XACML. Access control policies written in XACML could be amenable to multiple-duty-related security leakage, which grants unauthorized access to a user when the user takes multiple duties (eg, multiple roles in role-based access control policies).

Abstract Access control is one of the most fundamental and widely used security mechanisms. Access control mechanisms control which principals such as users or processes have access to which resources in a system. To facilitate managing and maintaining access control, access control policies are increasingly written in specification languages such as XACML. The specification of access control policies itself is often a challenging problem.

We propose a new static approach to Role-Based Access Control (RBAC) policy enforcement. The static approach we advocate includes a new design methodology, for applications involving RBAC, which integrates the security requirements into the system’s architecture. We apply this new approach to policies restricting calls to methods in Java applications. We present a language to express RBAC policies on calls to methods in Java, a set of design patterns which Java programs must adhere to for the policy to be enforced statically, and a description of the checks made by our static verifier for static enforcement. 1
