In hierarchical network security situation assessment model, there are many problems, such as subjective index weight factor, large evaluation index system, large amount of calculation and low efficiency. A network security situation assessment model and quantification method based on AHP is proposed to solve this problem. The AHP analytic hierarchy process (AHP) is combined with the hierarchical model of situation assessment to simplify the situation assessment problem. The D–S evidence theory is used to fuse the fuzzy results of multi-source equipment to solve the problem of single information source and large deviation of accuracy. Through the construction of three evaluation indexes of risk situation, basic operation situation and damage situation, the problem of large evaluation index system and low evaluation efficiency is solved. AHP analytic hierarchy process is used to determine the weights of different index items, so as to avoid the subjectivity and randomness of weighting factors. The simulation results show that the model can reflect the security status of the network as a whole, and the situation assessment is accurate and can better serve the high-level decision-making.
