Abstract
A technique allows for protecting a PCI device controller from a PCI BDF masquerade attack from Ring-and Ring-malware. The technique may use Virtualization technologies to create guest virtual machines that can use a hypervisor to allocate ACPI information from ACPI tables to a secure VM and using extended page tables (EPT) and VT-d policies to protect the MMIO memory range during illegal runtime events.
