A method for achieving atomicity while inspecting a running computer process using a copy-on-write process in a supervisor to generate a copy of a target's memory page being written to, prior to executing the write, the copy along with any unwritten to memory pages in the target being mapped to a measurement agent (MA) and used to reflect the state of the target at a particular moment in time which state when observed by the MA provides an atomic runtime inspection.

Methods for improving atomicity of runtime inspections

The present disclosure is directed towards methods and systems and methods for measuring the integrity of an operating system's execution and ensuring that the system's code is performing its intended functionality. This includes examining the integrity of the code that the operating system is executing as well as the data that the operating system accesses. Integrity violations can be detected in the dynamic portions of the code being executed.
