Booting a Linux Kernel in a Higher Privilege Level - Introduction to Linux Virtualization Based Security

Explore Linux Virtualization based Security (LVBS) in this 48-minute conference talk by Microsoft experts Thara Gopinath and Anna Trikalinou. Delve into the concept of hardening the Linux kernel and protecting critical resources using hardware virtualization and Hyper-V. Learn about the creation of an isolated virtual environment called Virtual Trust Level 1 (VTL1) and its separate Secure Kernel. Discover the journey of developing a Secure Kernel, including the decision to use a minimal Linux kernel. Examine the Secure Kernel boot sequence and the modifications made to the Linux Guest kernel to enable and launch VTL1. Gain insights into the integration with Secure Boot and the goals for hardening the Guest. Access the related code on GitHub to further enhance your understanding of LVBS implementation.
