Cross Bread Role Based Access Control for Extended Security at Azure in Cloud Computing
Cloud computing provides a computer user access to Information Technology (IT) services i.e. applications, servers, data storage without requiring an understanding of the technology or even ownership of the infrastructure. Privacy and Security are big issues in Cloud Computing. The cloud environment is a large open distributed system. It is important to preserve the data, as well as, privacy of users. Various access control models are in use, including the most common Mandatory Access Control (MAC), Discretionary Access Control (DAC) and Role Based Access Control (RBAC). This paper proposes the security enhancement in Role Based Access Model using Reference Ontology to restricts the number of user per role, number of transaction per user and adds the feature of backup and restoration.
