Extended Role Based Access Control with Blob Service on Cloud
This work tackles security and authorization challenges in cloud-based systems, but it appears incremental as it builds upon standard RBAC without introducing a fundamentally new approach.
The paper addresses limitations in existing role-based access control (RBAC) models by proposing an extended-RBAC model that enhances security through added constraints, and it applies this model to manage access to blob storage on cloud servers for end-users.
Role-based access control (RBAC) models have generated a great interest in the security community as a powerful and generalized approach to security management and ability to model organizational structure and their capability to reduce administrative expenses. In this paper, we highlight the drawbacks of latest developed RBAC models in terms of access control and authorization and later provide a more viable extended-RBAC model, which enhances and extends its powers to make any system more secure by adding valuable constraints. Later the Blobs are stored on cloud server which is then accessed by the end users via this Extended RBAC model.
