PAGE ERROR INSERTION IN VIRTUAL MACHINES Russian patent published in 2018 - IPC G06F12/00 G06F9/455 

FIELD: data processing.

SUBSTANCE: invention relates to the protection of computer systems from malicious programs. System contains a hardware processor for controlling: hypervisor, to provide a virtual machine containing a virtualized processor and virtualized memory to use a virtualized processor to perform the target process; and a memory introspection engine that runs outside the virtual machine and is configured to: determine, in accordance with the table of pages of the virtual machine, whether the target page of the virtual memory space of the target process is downloaded from the virtualized memory; and in response to, when the target page is unloaded from virtualized memory, direct insertion of specified page error into the virtual machine, and the page error results in the virtual machine operating system displaying the target page in a page of virtualized memory, and a direct error of the page is provided by the engine of introspection of the memory of a certain value in the field for inputting the event.
