Study on the Quantitative Vulnerability Model of Information System Based on Mathematical Modeling Techniques

Abstract

The idea of mathematical modeling is used to establish the quantitative model of information system vulnerability assessment, and the model is solved by using the partial differential method. The algorithm is realized by using VB programming, and it obtains the quantitative solution of information system vulnerability. Quantitative assessment of information system security and risk is the difficulty of system vulnerability assessment, and it establishes the risk model of system by means of mathematics modeling idea. The risk model is divided into the actual risk and the potential risk. The paper uses VB programming software, and establishes a quantitative model of information system evaluation by combining with partial differential method, and the algorithm is carried out the experimental verification by using the method of numerical simulation. Through the calculation, the mathematical modeling ideas can effectively obtain the vulnerability quantitative standard and the risk level of information system, which provides the technical reference for the research of information system security evaluation method.
