Towards Achieving Accountability, Auditability and Trust in Cloud Computing
نویسندگان
چکیده
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 we now have to consider large-scale virtual and physical distributed server environments to achieve (1) real-time tracing of source and duplicate file locations, (2) logging of a file’s life cycle, and (3) logging of content modification and access history. This position paper considers related research challenges and lays a foundation towards addressing these via three main abstraction layers of cloud accountability and a Cloud Accountability Life Cycle.

When we upload or create data into the cloud or the web, we immediately lose control of our data. Most of the time, we will not know where the data will be stored, or how many copies of our files are there. Worse, we are unable to know and stop malicious insiders from accessing the possibly sensitive data. Despite being transferred across and within clouds over encrypted channels, data often ha...
