Based on the systematic analysis of information security risk elements, a fuzzy influence diagram algorithm is introduced to solve the problem that the probability of threats in the assessment process and the value of information assets are difficult to quantify. According to the qualitative analysis, the information security risk impact map is drawn, and the fuzzy impact map evaluation algorithm is used to calculate the probability of information security risk, and the information security risk assessment conclusion is obtained. The conclusion shows that the key to applying fuzzy influence diagram to evaluate information security risk is to determine the fuzzy relationship between node status and frequency and between nodes, which is a simple and practical evaluation algorithm combining qualitative and quantitative, which provides a new idea for information security risk assessment.
