Abstract

See full text

Mechanisms to protect the integrity of memory of a virtual machine are provided. The mechanisms involve utilizing certain capabilities of the hypervisor underlying the virtual machine to monitor writes to memory pages of the virtual machine. A guest integrity driver communicates with the hypervisor to request such functionality. Additional protections are provided for protecting the guest integrity driver and associated data, as well as for preventing use of these mechanisms by malicious software. These additional protections include an elevated execution mode, termed “integrity mode,” which can only be entered from a specified entry point, as well as protections on the memory pages that store the guest integrity driver and associated data.
