Towards an analysis of data accountability and auditing for secure cloud data storage

Cloud technology, runs off-premise, provides an extensive information technology support and service that can offer as an on-premise version if on demanded as a virtualized solution for customers' technological requirements. Cloud computing put together the comprehensive solutions by integrating the different technology that provision Software, Platform and Infrastructure as services. Cloud, an integrated technology that delivers a complete, open and flexible solution, leads to a critical concern over its trust. The extensive use of virtualization in cloud especially in data storage capability put forth many security concerns to the customer. It is the time to prove the customer about the strength of the cloud security through enabling their data accountability and auditing mechanism. In this work we going to provide a systematic analysis of the data accountability mechanism and auditing approaches existing now in cloud. To strengthen the customers trust over the cloud technology and service, we provided a clear enhanced view on the cloud data security and also analyze the secured way of utilizing the advantages of cloud computing.
