There have been two parallel themes in access control research in recent years. On the one hand there are efforts to develop new access control models to meet the policy needs of real world application domains. In parallel, and almost separately, researchers have developed policy languages for access control. This paper is motivated by the consideration that these two parallel efforts need to develop synergy. A policy language in the abstract without ties to a model gives the designer little guidance. Conversely a model may not have the machinery to express all the policy details of a given system or may deliberately leave important aspects unspecified. Our vision for the future is a world where advanced access control concepts are embodied in models that are supported by policy languages in a natural intuitive manner, while allowing for details beyond the models to be further specified in the policy language.
