Performance Analysis of SAT-RBAC in Cloud Environments

Abstract

Cloud computing provides important support for the development of modern society with its flexible and efficient nature. In Cloud environment, the relationship between users and resources is more temporary and dynamic. Therefore, it is necessary to study the security technology of virtual machines in Cloud environment. The role-based access control (RBAC) model is an access control model for Cloud environments that provides adaptive authorization to users based on dynamic trust estimates. This paper first analyzes the technical aspects of Cloud computing, then introduces the self-security threats of virtualization and virtual machine security threats, and finally analysis the performance of the SAT-RBAC model (security and availability based trust relationship in RBAC) in Cloud environment. The model provides reference for Cloud computing security technology by isolating role access, comprehensive verification of user trust certificates and trust levels, and completing the protection of data storage, isolation, and access in Cloud computing platform. As a result, trust is combined with RBAC as one of its attributes for increasing flexibility, scalability, security, and resource access levels.
