ISO 21434
ISO/SAE 21434 is an international standard that provides a framework for addressing cybersecurity risks throughout the lifecycle of automotive systems. It defines requirements and guidelines for managing cybersecurity in road vehicles, from the concept phase to design, development, production, operation, and decommissioning. The standard aims to ensure that cybersecurity is integrated into the entire product development process, helping organizations identify and mitigate vulnerabilities, respond to incidents, and continuously improve their cybersecurity posture in response to evolving threats.
Clause 15 Threat analysis and risk assessment methods (TARA)
Clause 15 of ISO/SAE 21434 outlines the systematic approach to conducting threat analysis and risk assessment for automotive systems. The activities in this clause guide the identification of potential threats, the assessment of associated risks, and the evaluation of their impact on system security. Through structured methods like attack path analysis and impact assessments, organizations can prioritize risks and define appropriate mitigation strategies. The outcomes of these activities form a critical basis for cybersecurity requirements and design considerations, ensuring that the most significant risks are addressed and that the vehicle’s security posture is robust and resilient against emerging threats.
