Access control policies enforcement in a cloud environment: Openstack

摘要: Cloud computing has become a widely used paradigm in many IT domains such as e-health. It offers several advantages to the users, e.g. elasticity, flexibility and rapid sharing of huge set digital data. However, security privacy concerns still pose significant challenges. In particular, most identified problem is how enforce user's policy access control outsourced fact, cloud environments does not provide facilities support high level defined policies. For instance, swift storage component openstack supports only fine grained execute specific action on object. this paper, we designed implemented middleware policies while using primitives. An e-health collaborative application dedicated for remote diagnosis illustrate suggested approach.
