Dynamic Authorization Management Model Based on ASP.NET and WBS

A dynamic authorization management model based on ASP.NET technology and work breakdown structure (WBS) is proposed in this paper. This model introduces the concept of WBS, which is the project management method based on the systematic principle to set up the access control system in the .NET framework This model realizes the dynamic authorization in accordance with the task of work flow system, so it improves on the limitation of the RBAC that administers the authorization by ´Role´ and ´Function´ only. The practice has shown that this model has high security, flexibility and portability.
