Chen Chun-hui · Journal of Nanjing University of Technology · 2009
In the management information system with complicated organization structures and frequent changes of user privilege,the conventional RBAC(role-based access control) is not flexible enough and increases the expenses and complexity of management.With DAC,MAC and RBAC,a comprehensive access control model was presented,and the basic idea,structure and characteristics of the model were given.Then,the design and the application of the new model were described in the development of a college level management information system,and both the flexibility of management jurisdiction and the safety of the system were remarkably improved.
