Security Issues with Virtualization in Cloud Computing

Cloud Computing is a scalable system of shared resource pooling with the help of virtualization. For secure resource pooling, we need a secure way to isolate every virtual machine from each other. Hypervisors help in secure isolation of multiple virtual machines running on single physical hardware. The hypervisor is a piece of software which works between the guest virtual machines and the physical hardware. Hypervisors help in partitioning the actual hardware into multiple logical virtual hardware to be able to run multiple operating systems simultaneously. Security is a major concern when multiple tenants working on the same physical machine. Hypervisors are also known as virtual machine monitor which has the complete control over all the hosted virtual machines so in this way security related to hypervisors is a real critical concern. As the more small and medium businesses moving towards the cloud so as the security risks increase related to the privacy protection and control of data. In this paper, security threats and risks related to the virtualization in cloud computing and its viable counter measures are presented.
