Investigation of the secure paths set calculation approach based on vulnerability assessment

Abstract

An approach to the calculation of secure paths based on the routing model taking into account information security risks using the basic vulnerability criticality metrics is proposed and investigated. The approach for calculating route metrics uses obtained expressions, which characterize the information security risk in network links in the case of existing vulnerabilities. The results of the investigation showed that within the approach of calculating secure paths with increasing packet traffic, the paths in the network that contained links with the lowest weights, i.e. had the least weight of compromise, were loaded first. The transmission of the packet flow after overloading the more secure path was carried out in the following paths according to the values of the weights of the communication links. The paths in the network that contained the links with the highest weights were loaded last.
