PolicyDSL: Towards generic access control management based on a policy metamodel

Abstract

The paper presents a generic access control management infrastructure suitable for a broad set of systems. The generic infrastructure is based on our policy metamodel (level M2), which is used for the specification of the needed policy model (level M1) such as RBAC, GTRBAC, etc. Having a defined policy model, the abstract and concrete syntaxes of PolicyDSL, our textual DSL for expressing access control policies, are dynamically generated. A security expert is then able to express the actual access control policies (level M0) for the given access control model using the generated DSL. The presented solution can be applied, with no changes, to a number of systems that are based on different access control models or their variants. © 2013 IEEE.
