Title Virtualization Security: The Good, The Bad and The Ugly
Abstract The resurgence of virtualization has stimulated its wide adoption in desktop, cloud and mobile environments. With virtualization being a new systems software foundation, virtual machine monitors (or hypervisors) are now treated as the security foundation of the system software stack, due to the promise of being small and providing strict security isolation. In this talk, I will first question whether such a promise still holds in commodity hypervisors by reviewing the historical evolution of virtualization. Based on a negative answer, I will discuss a series of efforts to enhancing the security isolation while minimizing the trusted computing based of the virtualization stack, including leveraging a commodity hypervisor to isolate a group of process, using a nested hypervisor to transparently isolate virtual machines and completely offloading isolation functionalities into on-chip CPU. Finally, I will also describe a set of new security innovation enabled by virtualization, such as live updating, security introspection and fine-grained compartmentalization.
