Design And Implementation Of User Privilege Management In MIS Of Special Items

In many applications, the privilege management plays an important role. Through years of research, privilege management has been formed a more mature model, and is widely used in various application systems. Based on a MIS of special items of some department in Beijing, this subject is to study how to design and implement a privilege management system.The goal of the thesis is to develop a user privilege management system as a subsystem of MIS of special items to provide user management and access control functions. Now the MIS has began its test run, it effectively developed, utilized information resources of the enterprise and accelerated the pace of enterprise information technology, which has achieved good results through co-ordination with information technology of enterprise.Through the field research of application enterprise, this article analyzes and summarizes the requirements of user management and access control of MIS of special items; and the paper also proposes OSRBAC model, which extends role-based access control model. On this basis, the analysis, design and implementation of the elements of the OSRBAC model, the relationship between elements, the database table structure and the privilege management process are done, and on the base of basic class library, a graphical system of user privilege management is accomplished, so that administrators can flexibly configure user management and permissions control; in order to be easily integrated MIS, the system's external interfaces are also developed so that MIS of special items can easily call these interfaces and have effective control on the user's operating permissions.This paper not only proposes OSRBAC model based on RBAC model, which is more suited to their enterprise needs. The analysis, design and realization of the privilege management system based on the OSRBAC model are also done in this thesis, and the privilege management system are now used in MIS of special items of some department in Beijing, which has got a good application effect.
