Towards a Data-centric View of Cloud Security

摘要

Cloud security issues have recently gained traction in the research community, with much of the focus primarily concentrated on securing the operating systems and virtual machines on which the services are deployed. In this paper, we take an alternative perspective and propose a data-centric view of cloud security. In particular, we explore the security properties of secure data sharing between applications hosted in the cloud. We discuss data management challenges in the areas of secure distributed query processing, system analysis and forensics, and query correctness assurance, and describe our current efforts towards meeting these challenges using our Declarative Secure Distributed Systems (DS2) platform.
