Specifying and managing access control policies for large distributed systems is a non-triviai task. Commonly, access control policies are specified in natural language and later reformulated in terms of a particular access control model. This paper presents and discusses concepts for an object-oriented access model that is more suitable for describing access control policies for CORBA objects than the default access model specified in the OMG security service specification.
