Ensuring Security for Virtualization in Cloud Services

Cloud computing is defined as the process of providing IT related computing capabilities on demand based on Pay as you use system. Since Virtualization is the fundamental of Cloud computing, it is necessary to have more knowledge to avoid attacks, intrusions and system failures. This technology enables the creation of logical resources (instances) and make them to run concurrently by having different Operating systems with compatible applications over existing physical resources. Here we introduce an approach to provide the security for the Virtual machines and their required resources by allowing them to work normally without problems by utilizing the available underlying physical resources.
