A Prospective Study on Distributed Accountability and Trusted Data Sharing in Cloud Computing

Abstract

The key barrier to widespread uptake of cloud computing is the lack of faith in clouds by potential customers. While preventive controls for security and privacy measures are actively being researched, there is still little focus on detective controls related to cloud distributed accountability and audit ability. The complexity resulting from the sheer amount of virtualization and data distribution carried out in current clouds has also revealed an urgent need for research in cloud accountability, as has the shift in focus of customer concerns from server health and utilization to the integrity and safety of end-users’ data. This paper discusses key challenges in achieving a trusted cloud data sharing through the use of detective controls, and presents the trust cloud framework, which addresses accountability
in cloud computing via technical and policy- based approaches.
