Hypervisor-Based Integrity: Protecting Guest Kernels in Cloud Environments

Explore a comprehensive conference talk on protecting guest kernels in cloud environments using hypervisor-based integrity. Delve into Google's approach to enhancing cloud security, covering topics such as threat modeling, runtime protection, and the role of hypervisors as an additional security layer. Learn about the overall plan for both boot time and runtime security, performance impacts, technical challenges, and necessary changes for KVM/QEMU implementation. Gain insights into future developments and other security considerations in this informative presentation by Ning Yang and Forrest Yuan Yu from Google.
