Hypervisor-based interception of memory accesses

Abstract

A security agent configured to initiate a security agent component as a hypervisor for a computing device is described herein. The security agent is further configured to determine a subset of memory locations in memory of the computing device to be intercepted. The security agent component may then set intercepts for the determined memory locations. Setting such intercepts may include setting privilege attributes for pages which include the determined memory locations so as to prevent specific operations in association with those memory locations. In response to one of those specific operations, the security agent component may return a false indication of success or allow the operation to enable monitoring of the actor associated with the operation. When an operation affects another memory location associated with one of the pages, the security agent component may temporarily reset the privilege attribute for that page to allow the operation.
