Abstract
A system and method that tracks changes in system memory executed by a software program. An exemplary method includes referencing a memory access tracking file to a file descriptor of a memory monitoring process and registering one or more virtual memory areas of a tracked process to the memory access tracking file. Moreover, the method includes sending, by the memory access tracking file, event information of a write access to the memory monitoring process that identifies a virtual page, where the write access is performed by the tracked process to the virtual page. Finally, the method includes configuring the virtual page such that the tracked process can execute a subsequent write command to the virtual page.
