Survey of Security Problems in Cloud Computing Virtual Machines
Virtualization has become an attractive and widely used technology in today's computing. Indeed, the ability to share the resources of a single physical machine between several isolated Virtual Machines (VM) enabling a more optimized hardware utilization, as well as the easier management and migration of a virtual system compared to its physical counterpart, have given rise to new architectures and computing paradigms. Virtualization techniques are at the heart of Cloud Computing, and these techniques add their own vulnerabilities to those traditional in any connected computer system. This paper presents an overview of such vulnerabilities, as well as possible counter-measures to cope with them.
