SYSTEM AND METHOD FOR DETECTING ANOMALIES IN A TECHNOLOGICAL SYSTEM Russian patent published in 2021 - IPC G06F21/55 G06F11/22 H04L29/08 

FIELD: testing.

SUBSTANCE: invention relates to solutions for improving information security of a technological system and is intended to detect anomalies in a technological system. The technical result is achieved by using a method wherein: using a duplication tool at least one outgoing data package addressed to an element of the technological system is intercepted, wherein the duplication tool constitutes a secure operating system with hypervisor function support activated on the element of the technological system; information about said intercepted data package is transmitted by the duplication tool to a control tool via a secure connection; at least one incoming data package addressed to the element of the technological system is intercepted using the control tool, wherein the control tool is a secure operating system with hypervisor function support activated on the element of the technological system; the anomaly in the technological system is detected using the control tool if the intercepted incoming data package does not correspond with said information received from the duplication tool.

EFFECT: improved security of the technological system.
