SYSTEM AND METHOD OF COUNTERING ANOMALIES IN THE TECHNOLOGICAL SYSTEM Russian patent published in 2021 - IPC G06F21/53 

FIELD: computer technology for information security of a technological system.

SUBSTANCE: invention relates to the field of computer technology for information security of a technological system. The technical result described below is achieved due to the method of blocking the transmission of data packets in the technological system, consisting of stages at which: a) using the duplication tool, at least one outgoing data packet is intercepted, addressed to an element of the technological system, with the duplication tool being a secure operating system with support for the hypervisor function, running on the element of the technological system; b) over a secure connection, information about the said intercepted data packet is transmitted to the control device by means of duplication; c) the control tool is used to intercept at least one incoming data packet addressed to an element of the technological system, while the control tool is a secure operating system with support for the hypervisor function running on the element of the technological system; d) with the help of the control tool, the transmission of the intercepted incoming data packet to the element of the technological system is blocked if the intercepted incoming data packet does not correspond to the mentioned information received from the duplication tool.

EFFECT: increased information security of a technological system with the ability to counteract anomalies in the technological system.
