Attacking global routing is capable of harming millions of network devices (and also users) with much less effort than the well-known DoS or Ransomware attacks. The global routing protocol BGP-4, despite its fundamental significance, is not secure, because it is based on trust between the participants of global routing. In the absence of fast prospects for implementing a more secure global routing protocol, it is necessary to suggest approaches that could be applied at the scope of a large operator, industry, region, to mitigate the possible losses from attacks on global routing. For this purpose, two general directions of counteraction are proposed: a) prevention of own prefixes hijacking; b) identification of hijacked routes and blocking outbound traffic to the compromised prefixes. The first direction is proposed to be described as the task of searching for the most effective topological organization of inter-node links, which can reduce losses from route hijacking within a certain target group of nodes.
