Build a Network Security Situation Assessment Model Based on AHP

This paper proposes a network security situation assessment model based on the Analytic Hierarchy Process (AHP). The model decomposes complex network security issues into multiple levels and factors and uses AHP to combine qualitative and quantitative analysis to determine the relative weights of various factors, thereby achieving accurate assessment of the network security situation. This paper elaborates on the model construction process, including the design of the hierarchical structure, the construction of judgment matrices, the calculation of weights, and consistency checks. The model is validated through a large amount of real data. Experimental results show that the model has high accuracy and practicability and can provide a scientific basis for network security decision-making.
