Different facets of security in the cloud

Cloud computing is a long fantasized visualization of computing as a utility, where data owners can remotely store and access their data in the cloud anytime and from anywhere. Using a shared pool of configurable resources, users can be relieved from the burden of local data storage and upkeep. The security of cloud computing has always been an important aspect of quality of service from cloud service providers. However, cloud computing poses many new security challenges which have not been well investigated. This paper provides an analysis of cloud computing, cloud data storage security, the security risks that involve using the cloud, security policies, physical security, and software security pertaining to the cloud. Our research work indicates that cloud computing combined with a trusted computing platform can provide some important security services, including authentication, confidentiality, and integrity.
