A Management-Enhanced Model for RBAC |
| |
| Abstract: | The manner of permission management in Role-Based Access Control is similar to the actual one in application fields, and it greatly simplifies system management. How to define and manage hundreds of permissions, roles,users and relations among them ( all are called RBAC special framework in this article)in large systems is one key problem that models for RBAC must resolve. This article studies the management of RBAC special frameworks, takes the management relations among roles into frameworks, and puts forward Management-Enhanced Model for RBAC. Special frameworks created according to this model are very similar to the management structures in application fields, and can manage themselves. This model also supports dynamic maintenance of management formwork while it is working. |
