No Silver Lining: Information Leakage in Cloud Infrastructures
Abstract:
As more businesses and individuals migrate their workloads to cloud infrastructures, many are unaware of a potential issue inherent in these systems: information leakage, the potential inadvertent release of data through a Virtual Machine (VM) to another VM, which then transfers the information to a third party. An assumption is that there is no interaction between multiple VMs, even if they reside within the same cabinet. Unfortunately, this is not true. This paper presents a selected history of VM information leakage via various covert timing channel attacks and shows that over time the practicality of these attacks is increasing.
