- W203668226 abstract "This paper presents an architecture for implementation of multiple access control policies within a CORBASEC framework. CORBASEC is a security service specification provided by OMG for implementation of security in CORBA compliant systems. Because of the differences in ORB implementations among vendors and divergent security needs of the CORBA based applications in different commercial markets, CORBASEC provides a general security reference model. The reference model can then be used by implementers to customize a security model depending upon their system and application needs. We have extracted one such model from the CORBASEC security reference model (or framework) to be used in an architecture whose objective is to support multiple access control policies within a single unified system. Throughout this paper we refer to this architecture using the acronym MACP. The central component of MACP is an Access Computation Server (ACS) which hosts multiple modules representing different security policies. These modules are implemented using an expressive logic based “Authorization, Policy Rules Specification & Decision Language” (APRS-DL) which provides constructs for capturing the access attributes and policy rules associated with several well known access control policies. We illustrate the use of APRS-DL for generation of access control decisions for a Discretionary Access Control (DAC) policy using the Role Based Access Control (RBAC) authorization management concept." @default.
