Towards Achieving Accountability, Auditability and Trust in Cloud Computing

Free registration required

Executive Summary

The lack of confidence in entrusting sensitive information to cloud Computing Service Providers (CSPs) is one of the primary obstacles to widespread adoption of cloud computing, as reported by a number of surveys. From the CSPs' perspective, their long-term return-on-investment in cloud infrastructure hinges on overcoming this obstacle. Encryption and privacy protection techniques only solve part of this problem: in addition, research is needed to increase the accountability and auditability of CSPs. However, achieving cloud accountability is a complex challenge; as the authors now have to consider large-scale virtual and physical distributed server environments to achieve real-time tracing of source and duplicate file locations, logging of a file's life cycle, and logging of content modification and access history.
