Cloud Computing In The Application Of Privilege Management

In this paper, a privilege management model based on cloud computing is established. Cloud computing as a new business model, it reflects the superiority in the massive data processing, heterogeneous and other aspects. By cloud computing providers and users of the respective relations,cloud can be divided into public, private and mixed. Public cloud is by a number of enterprises to share use the cloud environment, private cloud becomes more and more guarantee in the security, reliability and control terms, and the mixed cloud is a combination of both. There are some traditional access control methods, DAC, MAC, RBAC and so on, this paper has improved based on RBAC, and propose a common privilege management service. The core idea of the service is that the privilege management is independent from the system and packaged into the public cloud service, enterprises can build their own private cloud and the application is packaged for the service, while using the ideas of Web Service architecture to achieve client,public cloud and private cloud communication. Finally, through the CXF development framework, achieves web service and the aim to verify the scalability, availability, and correctness of the model in practice.
