Layered security approach in cloud

Cloud refers to a collection of nodes and the Cloud computing model focuses on the Cloud to provide the services to the customers. The model separates the client machine from the data and the application in use thus increases the Robustness and the Cost-Effectiveness of the Application. This paper introduces the security model for services like SaaS, DaaS etc. Its main purpose is to define a new solution to the security concerns of the cloud consumers using different approaches at different levels. This proposed security approach can me mingled with other emerging security proposals for implementing a robust and trustworthy cloud security.
