METHOD OF DETECTING AND COUNTERACTING DENIAL OF SERVICE ATTACKS Russian patent published in 2025 - IPC G06F21/55 G06N3/02 

FIELD: physics.

SUBSTANCE: invention relates to a method of detecting and counteracting denial of service attacks. Disclosed is a method during which, by processing network traffic, a training table is formed, wherein network characteristics and interaction characteristics are used to form, a neural network of the auto-encoder type is trained, creating tables of threshold values of network characteristics and interactions, then forming the test table, calculating the average reconstruction error for the test table, if threshold values are exceeded, all packets from an external digital data transmission network are blocked from passing to the local digital data transmission network, for which the set of two IP addresses, protocol and server port matches one of the abnormal interactions.

EFFECT: high probability of detecting and protecting against types of denial-of-service attacks using attack source IP address substitution, distributed attacks, deflected attacks and denial-of-service attacks with increasing activity.
