Abstract:
In multi-tenancy cloud environments, physical resources are transparently shared by multiple Virtual Machines (VMs) belonging to multiple users. Implementing an efficient access control mechanism in such environments can prevent unauthorized access to the cloud resources. In this paper, we propose an access control mechanism called CloudGuard that provides scalable and secure access control to the cloud in the context of multi-tenancy cloud environments. Such a mechanism prevents malicious tenants from generating and sending unauthorized traffic to the cloud network. Numerical results show that CloudGuard offers better system throughput in critical or high-risk multi-tenancy cloud network environments, where the amount of intrusion traffic is high.
