A Sequence-Based Access Control Framework for Reliable Security Management in Clouds

Cloud Computing and its' security and privacy concerns as well as countermeasures are one of the highly debated topics in today's IT industry. One of the most challenging security issues in clouds is to define and manage different levels according to isolation, service delivery and scalability concepts in clouds. These security levels need to be protected from disclosing to unauthorized users. Policy-Management models are the most appropriate solutions to create and manage security levels in clouds. However, these models increase the process of matching access requests to defined policies considerably. In this paper, we proposed a reliable access management framework based on multi-level policies and sequences. The suggested model introduces each level of security as s sequence according to the inheritance concepts to classify security levels efficiently and to enhance the process of access control by elimination of unnecessary re-matching. our results showed the suggested model is able to decrease the access response time without affecting the security of the environments.
