SYSTEM AND METHOD OF MONITORING OPERABILITY OF PROCESSES IN OPERATING SYSTEM Russian patent published in 2024 - IPC G06F12/14 G06F21/52 

FIELD: information security.

SUBSTANCE: result is achieved due to steps, according to which: converting the source code of the program into an equivalent machine code; constructing control flow graphs, which reflect the structure and syntax of the source code of the program; converting control flow graphs into call flow graphs using target instructions received from the operating system; generating at least one control flow signature based on the generated call flow graphs; starting a control flow monitor, after which a target process corresponding to said program is launched in the operating system; intercepting, by means of a control flow monitor, instructions of said program executed by the target process; checking the intercepted instructions for compliance with at least one control flow signature of said target process; if the instructions of the target process do not match the signature of the control flow, an error in the operation of the target process is determined.

EFFECT: high efficiency of detecting malfunction of a process in an operating system.
