This paper proposes a cyber security risk assessment methodology for rolling stock onboard communication systems based on the Common Vulnerability Scoring System(CVSS),introduces the workflow of the method in detail,and carries out defect probability and impact assessment,and also derives the cyber security level corresponding to the risk range of each system defect.Finally,it is applied to cyber security risk assessment activities of an overseas metro onboard communication system project,laying a foundation for the subsequent system optimization activities and cyber security risk repositioning after taking optimization measures.
