An enhanced security framework for a cloud application

Abstract

Cloud computing has gained momentum over the past few years where numerous business domains have shown a radical shift from their traditional software. Cloud apps can run weeks with minimum cost and user maintenance, which overcomes the drawback of a traditional software approach. However, cloud security is still in its infancy stage; hence, there are a numerous security issues possible. The purpose of this paper is to device a mechanism to store and retrieve data securely from cloud, overpowering as many threats as possible. The paper starts with a general introduction about cloud security and its advantages, which leads way to the major security challenges known about cloud and a framework to overcome it. We specifically concentrate on secure access of data over cloud, sharing data between multiple cloud users and the cloud data center. A simulator “Cloudsim” has been used.
