Tracking of Data Leaving the Cloud

Data leakages out of cloud computing environments are fundamental cloud security concerns for both the end-users and the cloud service providers. A literature survey of the existing technologies revealed the inadequacies of current technologies and the need for a new methodology. This position paper discusses the requirements and proposes a novel auditing methodology that enables tracking of data transferred out of Clouds. Initial results from our prototypes are reported. This research is aligned to our vision that by providing transparency, accountability and audit trails for all data events within and out of the Cloud, trust and confidence can be instilled into the industry as users will get to know what exactly is going on with their data in and out of the Cloud.
