- [Instructor] Virtualization forms the underlying fabric of the cloud. However, with virtualization comes another layer of risks, including hypervisor-specific threats intervirtual machine attacks and blind spots, and virtual machine sprawl. Added to this, new threats such as instant-on gaps, commingling, and residual data destruction also complicate life in a virtual world. The evolution of virtualization revolves around software known as the hypervisor. There are two forms of hypervisor. Type 1 hypervisors run at the hardware level. This is known as running on bare metal. The hypervisor contains all the features necessary to manage the underlying hardware, and prevents para-virtualized devices to the virtual machines which run on top of it. Type 2 hypervisors run on a host operating system. They're not as efficient as type 1 hypervisor because of the underlying software, and they also inherit all of its vulnerabilities.…
