Comparing the expressive power of access control models is recognized as a fundamental problem in computer security. Such comparisons are generally based on simulations between di...
This paper presents a policy-based framework for managing access control in distributed heterogeneous systems. This framework is based on the PDP/PEP approach. The PDP (Policy Deci...
In this paper we describe a mainframe access control system (DENT) and its associated delegated administration tool (DSAS) that were used in a financial institution for over 20 y...
