Access control is a security mechanism to protect resources from unauthorized access. The most popular role-based access control model (RBAC) Following the discretionary access control (DAC) and mandatory access control (MAC) access control model. In RBAC, users and permissions separation greatly simplifies permissions management, compared with the traditional model of access control, RBAC is a policy neutral model, mandatory access and discretionary access control can be achieved by configuring;, RBAC application The contents of the good characteristics. It is precisely because of the above-mentioned characteristics of RBAC, in theory and practice has been more and more attention. Although RBAC is now the most widely used access control standards, but when the system becomes particularly huge (role) contains hundreds of doubling the amount of information, especially when running multiple applications, plus enterprise organization the frequent changes of the structure, human resources, and lead to complicated rights management. Therefore, under the premise of ensuring the safety of the system, simplify rights management system work, has important practical significance. Multi-system access control management difficult problem for a business, drawing on the thinking of the Composite RBAC model, a the the RBAC Model-ERBAC extended (extended role based access control). The model application system is divided into the organizational structure level and system level; the Composite RBAC model, this paper introduced in the organizational structure level positions, the organization of these two elements, the \mapping of reality organization; \This not only reduces the difficulty and workload of the development and easy maintenance of the system. Need only change when the organizational hierarchy of the elements in the organizational structure level related adjustments to adapt to change; system permissions or system changes in the number of elements of the \make changes. In addition, it fully enhances the safety management system performance, the best big possible to reduce the complexity of management and maintenance, well adapted to the needs of large enterprises or government. Then detailed design of ERBAC model system, and the background of the the information project supervision system, combined with the actual needs of the project, the implementation of the system access control module based on the J2EE platform to prove the feasibility and correctness of the model.
