The cloud reduces the user’s burden to many folds. But cloud providers and cloud users with dynamic relationship, are in distinct security domains. Amongst various challenges with cloud, the crucial one is to detect and protect the user’s data from unauthorized accesses. In cloud, users are not legendary by their predefined identities. Instead, they are providing accesses based on their characteristics and attributes. This work is focusing on available access control mechanisms and one that applicable for cloud environment. The paper also proposes an Efficient and Flexible Role-Based Access Control (EF-RBAC) mechanism for the cloud computing environment to achieve confidentiality and security. RBAC limits the accesses for resources within an organization to authorized users only and also guarantees that a user can solely access specific information they are authorized for by the organization policy. The proposed scheme adds flexibility to the RBAC for better cloud user’s experience.
