Abstract
Official abstract text for this publication.
Described systems and methods allow protecting a host system from malware using virtualization technology. In some embodiments, a memory introspection engine operates below a virtual machine (VM) executing on the host system. The engine is configured to analyze the content of a virtual memory page used by software executing within the VM, and/or to protect the respective content from unauthorized modification, for instance by malware. When the respective content is swapped out of memory, the memory introspection engine injects a page fault into the respective VM, to force a swap-in of the respective content.
First claim
Opening claim text (preview).
What is claimed is: 1. A host system comprising a hardware processor configured to operate: a hypervisor configured to expose a virtual machine comprising a virtualized processor and a virtualized memory, the virtual machine configured to employ the virtualized processor to execute a target process, wherein exposing the virtual machine comprises configuring a data structure to store a current state of the virtualized processor, the data structure comprising an event injection fiel…
