Abstract:
Cloud computing is changing the IT delivery model to provide on-demand self-service access to a shared pool of computing resources (physical and virtual) via broad network access to offer reduced costs, scalability, flexibility, capacity utilization, higher efficiencies and mobility. In many instances cloud computing builds on the capabilities of a virtualized computing infrastructure enabling multi-tenancy, scalability and a highly abstracted cloud model. Even though cloud computing provides compelling benefits and cost-effective options for IT hosting and expansion, security of applications and data remains a number one business objective. It is therefore essential to ensure adequate security not only for cloud computing, but also for the underlying technologies enabling cloud computing. Management should understand and analyse risks in order to safeguard systems and data. The focus of this paper is on mitigation for virtualization security risks as a fundamental step towards secu
re cloud computing environments.
