Abstract：Cloud computing places an organization’s sensitive data in the control of a third party, introducing a significant level of risk on the privacy and security of the data. We propose a new management and security model for cloud computing called the Private Virtual Infrastructure (PVI) that shares the responsibility of security in cloud computing between the service provider and client, decreasing the risk exposure to both. The PVI datacenter is under control of the information owner while the cloud fabric is under control of the service provider. A cloud Locator Bot pre-measures the cloud for security properties, securely provisions the datacenter in the cloud, and provides situational awareness through continuous monitoring of the cloud security. PVI and Locator Bot provide the tools that organizations require to maintain control of their information in the cloud and realize the benefits of cloud computing.
