An Approach for Specifying Access Control Policy in J2EE Applications

Abstract

Most applications based on J2EE platform use role- based access control as an efficient mechanism to achieve security. The current approach for specifying access rule is based on methods of Enterprise JavaBeans (EJBs). In large-scale systems, where a large number of EJBs are used and the interactions between EJBs are complex, direct use of this method- based approach is error-prone and difficult to maintain. We propose an alternative approach for specifying access control policy based on the concept of business function.
