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 from a particular access control policy and from factors that are...
View ArticleDesign and Implementation of Resource Access Decision Server
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...

View ArticleOn the Benefits of Decomposing Policy Engines into Components
In order for middleware systems to be adaptive, their properties and services need to support a wide variety of application-specific policies. However, application developers and administrators should...
View ArticlePerformance Considerations for a CORBA-based Application Authorization Service
Resource Access Decision (RAD) Service allows separation of authorization from application functionality in distributed application systems by providing a logically centralized authorization control...
