An approach and its implementation for cloud computing security

With the increasing popularity of the datacenter provided by Cloud computing, the datacenter security is becoming an important issue. Also there are other issues to be concerned about such as its speed and standard, but data security is the biggest one. When an organization uses a remote datacenter provided by Cloud, it needs to maintain the confidentiality of the outsourced data and ensure only authorized user or client is allowed to access its data resource. In this paper, we investigate the security issue related to datacenter of cloud computing and propose a security approach for it. We use a formal logical method to specify the data and employ intelligent agents to enforce appropriate security rules on it. We outline the authentication mechanism and present a detailed authorization or access control approach. The implementation of the proposed approach will be discussed and investigated. The authentication and the authorization mechanisms work together to prevent any unauthorized attempt to data stored in the datacenter.
