A Survey on Context Security Policies in the Cloud

With the pervasion of cloud computing new security risks are created. A promising approach to alleviating these risks is to provide a security-by-design framework that will assist cloud application developers in defining appropriate context-driven access control policies. This paper surveys different approaches to context-driven access control, as well as different modelling formalisms for representing access control policies. The aim of this survey is to assess the appropriateness of existing approaches for the construction of a generic security-by-design framework, in particular one which is exposed as a PaaS offering.
