METHOD FOR ASSESSMENT OF IMPORTANCE OF NODES OF INFORMATION AND COMMUNICATION NETWORKS Russian patent published in 2023 - IPC G06F21/62 

FIELD: computer technology.

SUBSTANCE: invention relates to the field of computer technology for provision of security of information and communication networks for data transmission. A database of weight factors of network nodes is formed, a network traffic is monitored, during which attack sources – the latest node, from which IP packets come, defined with an attack detection system as dangerous and threatening for network functioning, are determined, a network graph is built, all possible network paths for all “attack source – protection object” pairs are determined, importance of nodes belonging to paths determined for all “attack source – protection object” pairs is assessed by calculating a node centrality value, taking into account weight factors of nodes: an attack source and a protection object, nodes are ranked by an importance degree, impossibility of reception and transmission of IP packets with nodes with the highest rank from attack sources is provided with available means, and the end of an attack to each protection object is checked, and, if the attack continues, actions, according to the method, are repeated, starting from calculation of node centrality.

EFFECT: increase in the reliability of assessment of importance of network nodes to provide network security.
