The aim of the work is to formalize a fast computable network security metric intended for use in optimization problems aimed at rebuilding the network according to security requirements.
The problem of assessing the security of a network infrastructure is considered. The aim of the work is to formalize a fast computable network security metric intended for use in optimization problems aimed at rebuilding the network according to security requirements. Three metrics with varying degrees of detail are proposed to achieve this goal. To do this, a set of essential features of the network infrastructure has been formed. The level of detail of the metric allows taking
