A resource access decision service for CORBA-based distributed systems

Decoupling authorization logic from application logic allows applications with fine-grain access control requirements to be independent of a particular access control policy and from factors that are used in authorization decisions as well as access control models, no matter how dynamic those policies and factors are. It also enables elaborate and consistent access control policies across heterogeneous systems. We present the design of a service for resource access authorization in distributed systems. The service enables one to decouple authorization logic from application functionality. Although the described service is based on CORBA technology, the design approach can be successfully used in any distributed computing environment
