Abstract


Access control network security and protection strategy is its main task to ensure that network resources are not illegal to use and access . Traditional access control already can not meet the growing demand for security . Increase the role of the concept of role-based access control (RBAC) role has certain access rights authorized by the user is mapped to a role in an organization , can be based on the role played by the user access authorization and control , thus effectively integrate the advantages of traditional access control technology while overcoming the shortcomings of traditional access control technology , enterprise protection strategy implementation process will be more flexible and provide a better environment for security policy for administrators . This paper first analyzes the traditional access control DAC , the MAC and role-based access control the RBAC and detailed analysis study RBAC96 model . On the basis of analysis of the RBAC96 model extended to RBAC96 model . Increasingly complex and growing workload , enables administrators work more difficult for the role and number of users will continue to grow with the continuous expansion of the system , so that the user - the role of \the access control of the reduction in efficiency , in this improved model of the introduction of the concept of the user group . RBAC model does not audit function , the operation authorized users without any restrictions , any operation which can be carried out within the scope of its authority , the operation authorized users there is no monitoring of the situation , the audit will be introduced to the system . This article gives the formal definition of the extended RBAC model join the grouping and audit functions , and detailed introduction to the group and audit of two parts . The last extended RBAC model is applied to the university office automation systems , given a detailed access control system access control , user management , role management , rights management to the design of each module , and finally introduces the realization and operation of the system .
