FIREWALL SYSTEM Russian patent published in 2019 - IPC H04L12/66 G06F21/62 

FIELD: physics.

SUBSTANCE: invention relates to the field of firewalling, used to prevent unauthorized access and exchange of information between various users of computer networks. Technical result is achieved due to preliminary analysis of incoming traffic flow on traffic belonging to a previously established connection, parsing packets to obtain data from packets on a channel, network, transport and application layers, splitting the obtained data from packets into clusters, making a decision on each packet in clusters based on established rules of processing network packets, detecting deviations of network traffic corresponding to processing rules, from a normal traffic profile of packets, updating established rules for processing network packets.

EFFECT: technical result is faster processing of network traffic based on clustering data with simultaneous thorough filtering thereof due to that each packet is checked by a set of rules, as well as in detecting anomalies.
