hGuard: A Framework to Measure Hypervisor Critical Files

, 2013
Virtualization has been widely adopted in current computer systems. A key part of virtualization is a hypervisor, which virtualizes physical resources to be shared among multiple guest virtual machines (VMs). Configuration files and security policy files

On the Impossibility of a Perfect Hypervisor

CoRR
We establish a fundamental impossibility result for a `perfect hypervisor', one that (1) preserves every observable behavior of any program exactly as on bare metal and (2) adds zero timing or resource overhead. Within this model we prove two theorems. (1) Indetectability Theorem.

Deferred DMA Attack: A Threat for Bypassing the IOMMU in Dynamic Hypervisors

IEEE Access
The Input–Output Memory Management Unit (IOMMU) is a crucial hardware component for enforcing access control for bus-master devices on the main memory. When properly configured by a hypervisor, it provides reliable protection against Direct Memory
