Cloud computing has changed the entire process that distributed computing used to present e.g. Grid computing, server client computing. Cloud computing describes recent developments in many existing IT technologies and separates application and information resources from the underlying infrastructure. Cloud computing security is an important aspect of quality of service from cloud service providers. Security concerns arise as soon as one begins to run applications beyond the designated firewall and move closer towards the public domain. In violation of security in any component in the cloud can be disaster for the organization (the customer) as well as for the provider. In this paper, the authors propose a cloud security model and security framework that identifies security challenges in cloud computing.
