An Experimental Study of Cascading Performance Interference in a Virtualized Environment
In a consolidated virtualized environment, multiple Virtual Machines (VMs) are hosted atop a shared physical substrate. They share the underlying hardware resources as well as the software virtualization components. Thus, one VM can generate performance interference to another co-resident VM. This paper explores the adverse impact of performance interference from a security perspective. The authors present a new class of attacks, namely the cascade attacks, in which an adversary seeks to generate performance interference using a malicious VM. One distinct property of the cascade attacks is that when the malicious VM exhausts one type of hardware resources, it will bring \"Cascading\" interference to another type of hardware resources.
