  2. Abstract:
    Decoupling authorization logic from application logic allows applications with fine-grain access control requirements to be independent from 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 polices and factors are. It also enables elaborate and consistent access control policies across heterogeneous systems. We present design of a service for re-source access authorization in distributed systems. The service enables 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.

  2. Abstract:
    Decoupling authorization decision logic enables implementation of complex and consistent access control policies across heterogeneous systems. However, this is difficult, if not impossible to implement by exclusively using general-purpose infrastructures such as CORBA Security Service. In response to this limitation of CORBA Security service the Object Management Group (OMG) has adopted a Resource Access Decision (RAD) Facility, an authorization service for distributed systems, as a pre-final standard. By using RAD facility, developers can implement systems with authorization logic decoupled from application-specific logic and decentralized evaluation and administration of the access policies.

    This report documents the design and implementation of a Resource Access Decision (RAD) facility. The report covers the different components that comprise a RAD system, their designs, functions and interdependencies. The RAD prototype allows studying the validity of the framework and conduction of experiments in the research of distributed access control. Since the design of the prototype is heavily influenced by design patterns, the prototype can easily be maintained and augmented with more complex access control mechanisms.
