Abstract


Enterprises to build a series of Web applications, rights management of each system is custom development, tightly coupled applications, it is difficult to achieve the rights management reuse inconvenience, but also give a the enterprise unified user and authorization management. Role-based access control model RBAC-based access control model is currently the most widely used. The modern enterprise of constantly changing user permissions, only adjust the role to change the user authorization, it is difficult to meet the changing needs of the complex situations; authorization of the traditional RBAC model conflict resolution strategies validity. To solve the above problem, the paper further extension of the RBAC model users and roles of inheritance and precedence constraint driven hybrid access control model IPC_URBAC and SOA-based Web Service technology designed to achieve a platform-independent, loosely coupled, easy to expand unified access control mechanisms. This paper first analyzes the Discretionary Access Control DAC, mandatory access control (MAC) and based on the advantages and disadvantages of role-based access control RBAC verify RBAC model is more suitable for Web application security management needs. Then, by analysis of the deficiencies of the RBAC model extended the RBAC model IPC_URBAC model, given the definition of inheritance and precedence constraints, proposed individual and priority conflict resolution strategies, and gives the algorithm for solving user permissions. Secondly, based on the SOA thought and improved IPC_URBAC model design to achieve a unified access control mechanisms, analysis of the characteristics of the unified access control mechanisms, given the integrated Web application system. Finally, the combination of participating in the development of the CRM project describes the application of the unified access control mechanisms to achieve. The model of IPC_URBAC Add inherited constraints to flexible control user authorization, effectiveness, and enhance the flexibility of the model authorization; design inheritance and precedence constraints, as well as individuals and give priority to solving strategies the users and roles authorized conflict enhanced model of security. In this paper, the extension of the constraint and authorization of RBAC model has certain referential significance. Control into a Web services based on SOA architecture ideas permissions to achieve a maximum particle size of the security model reusability permissions to control the maximum independent Web application system permissions control upgrade legacy systems separate by The call permissions service implementation with different Web applications systems integration, and also provide some new ideas for the successful practice of SOA.
