Abstract
Vulnerability analysis is one of the important processes of cyber security risk assessment. With the gradual application of industrial Internet, intelligent technology, intelligent systems and equipment in the field of nuclear power, the methods of cyber attacks on nuclear power plants are gradually diversified, and the cyber security threats faced by industrial control systems are also increasing, and their cyber security vulnerabilities need to be continuously assessed. In this paper, combined with the current threat characteristics of nuclear power plant industrial control system operating environment, the cyber security vulnerability of the system is studied, and the typical vulnerability analysis items of nuclear power plant industrial control system are proposed to analyze the vulnerability characteristics of the system under different cyber security threat factors. At the same time, a vulnerability evaluation method based on functional safety impact analysis is formed, which takes the security level and consequence degree of the attacked system as the basic score, and the impact degree on the design of the defense-in-depth defense line as the weight for comprehensive scoring. Assess the vulnerability level to provide reference for the cybersecurity risk assessment and design improvement of the industrial control system of the nuclear power plant.
