Our key contribution is showing how we can perform continuous monitoring and leverage information across different layers of a virtualized computer system to detect malicious attacks and accidental failures. For monitoring software running inside a virtual ma- chine, we introduce HyperTap and Hprobes, which are out-of-VM monitoring frameworks that facilitate detection of security and reliability incidents oc- curring inside a VM. For monitoring the hypervisor, we introduce hShield, a Control-Flow Integrity (CFI) enforcement method to detect VM-escape at- tacks. HyperTap, Hprobes, and hShield create a complete chain-of-trust for the entire virtualization software stack.
