Abstract

The embodiment of the invention provides a safety vulnerability risk assessment method and device for a high-speed train operation control system. The method comprises the steps of acquiring basic index parameters, time index parameters and environment index parameters, representing safety vulnerability risks, of the high-speed train operation control system; respectively calculating a basic indexscore, a time index score and an environment index score based on corresponding calculation modes; and calculating the safety vulnerability risk degree of the high-speed train operation control system according to the basic index score, the time index score, the environment index score and the service range of the high-speed train operation control system. According to the embodiment of the invention, the security vulnerability risk assessment is associated with the high-speed train operation control system, and the vulnerability risk is assessed from different dimensions, so that the assessment applicability is improved, the vulnerability risk assessment process is simplified, the vulnerability severity is quantified, and the method is used for solving the emergency vulnerability.

Description

technical field [0001] The invention belongs to the technical field of railway transportation, and in particular relates to a safety vulnerability risk assessment method and device for a high-speed train operation control system. Background technique [0002] During software development, it is crucial to consider security threats. Over the past few years, there has been a significant increase in the number of reported incidents and the harm such incidents cause to organizations. The work of dealing with threats needs to be done in an efficient manner. , the priority can be derived from the threat's risk level (defined as the likelihood of occurrence and consequences for the asset). Currently leveraging the Common Vulnerability Scoring System (CVSS), an industry open standard, it uses different metrics to calculate the severity of a vulnerability and help determine the urgency and importance of the required response. It is hoped that the improved algorithm of the CVSS scorin...
