Abstract

This paper analyzes access control mechanisms of the Enterprise Java Beans (EJB) architecture and defines a configuration of the EJB protection system in a more precise and less ambiguous language than the EJB 3.0 standard. Using this configuration, the authors suggest an algorithm that formally specifies the semantics of authorization decisions in EJB. The level of support is analyzed for the American National Standard Institute’s (ANSI) specification of Role-Based Access Control (RBAC) components and functional specification in EJB. The results indicate that the EJB specification falls short of supporting even Core ANSI RBAC. EJB extensions dependent on the operational environment are required in order to support ANSI RBAC required components. Other vendor-specific extensions are necessary to support ANSI RBAC optional components. Fundamental limitations exist, however, due to the impracticality of some aspects of the ANSI RBAC standard itself. This paper sets up a framework for assessing implementations of ANSI RBAC for EJB systems.
