A Network Vulnerability Assessment Method Based on Asset Weight

According to the characteristics of frequent node interaction and obvious differences in applications of marine network, this paper takes the degree of information interaction between assets as the basis for measurement. With the concept of logical edge number introduced, serial static and dynamic elements, such as upstream traffic, downstream traffic, number of logical edges, and number of applications, are taken as the evaluation indexes. Assigned values based on expert experience, the entropy weight method is applied to calculate and verify the comprehensive weight of network assets. According to the preset classification rules and CVSS vulnerability-scoring model, the vulnerability assessment of the virtual marine network is carried out. The results show that the selected indexes can calculate the weight of assets scientifically, and the method can provide a basis for the security optimization of the measured network.
