3.2
cybersecurity management system; CSMS
risk-based system method
Note: It includes organizational processes, accountability, and governance to deal with risks associated with vehicle cyber threats and protect vehicles from cyber attacks.
[Source: GB/T 44373-2024, 3.11, modified]
3.3
risk
impact of vehicle cybersecurity uncertainty
Note: The risk is expressed in terms of attack feasibility and impact.
3.4
risk assessment
process of discovering, identifying and describing risks, understanding the nature of risks and determining the level of risks, and comparing the results of risk analysis with risk criteria so as to determine whether the risks are acceptable
3.5
threat
potential cause of an unexpected incident that may lead to damage to a system, organization, or individual
3.6
vulnerability
weakness in the asset or mitigation measures that may be exploited by one or more threats
3.7
