Item Private Virtual Infrastructure for Cloud Computing(2009) Krautheim, F. JohnCloud 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.Item Private Virtual Infrastructure: A Model for Trustworthy Utility Cloud ComputingKrautheim, F. John; Phatak, Dhananjay S.; Sherman, Alan T.Private Virtual Infrastructure is a security architecture for cloud computing which uses a new trust model to share the responsibility of security in cloud computing between the service provider and client, decreasing the risk exposure to both. Private Virtual Infrastructure is under control of the information owner while the cloud fabric is under control of the service provider. The Private Virtual Infrastructure architecture comprises a cluster of trusted computing fabric platforms that host virtual servers running an application server with a Locator Bot security service. The cloud Locator Bot pre-measures the cloud platform for security properties to determine the trustworthiness of the platform. The Locator Bot uses Trusted Execution Technology and virtual Trusted Platform Modules to pre-measure the target environment and securely provision the Private Virtual Infrastructure in the cloud thus protecting information by preventing data from being placed in malicious or untrusted environments. Private Virtual Infrastructure — including Locator Bot — provides organizations tools to maintain control of their information in the cloud and realize benefits of cloud computing, with assurance that their information is protected. This paper presents a cloud trust model, Private Virtual Infrastructure architecture, and a Locator Bot protocol in enough detail to support further analysis or implementation.
