Abstract
In this talk, I will present two research projects. First, I will present a framework called Hyperprobe, which for the first time introduces a concept called virtual machine extrospection, in which attackers or cloud customers collect sensitive information about the physical machine from within a virtual machine. Second, I will present Kshot, which introduces a live kernel patching approach that leverages Intel SMM and SGX to patch Linux kernel security vulnerabilities at runtime. At the end of the talk, I will briefly discuss my other research projects and plans.
