In this paper we identify the requirements for the definition of a security framework for distributed access control in dynamic coalitions of heterogeneous systems. Based on the elicited requirements, we introduce the POLIPO framework that combines distributed access control with ontologies to give a globally understandable semantics to policies, enabling interoperability among heterogeneous systems.
