What is ISO/SAE 21434?
ISO/SAE 21434 is the international standard for cybersecurity engineering in road vehicles. It provides a comprehensive framework for managing cybersecurity risks throughout the entire lifecycle of automotive systems. From concept and development to production, operation, maintenance, and decommissioning. The standard addresses the increasing complexity and connectivity of modern vehicles, which makes them more vulnerable to cyber threats.
ISO 21434 requires organizations to identify and assess potential cybersecurity threats and vulnerabilities, implement risk management processes, and ensure that appropriate security controls are in place. This includes activities such as Threat Analysis and Risk Assessment (TARA), secure software development practices, incident response planning, and continuous monitoring for emerging threats. The standard also emphasizes the importance of collaboration across the supply chain, requiring suppliers and partners to adhere to consistent cybersecurity practices.
By following ISO 21434, automotive manufacturers and suppliers can demonstrate due diligence in protecting vehicles from cyberattacks, safeguard customer data, and comply with regulatory requirements. The standard is closely aligned with other automotive safety standards, such as ISO 26262 (functional safety), ensuring a holistic approach to both safety and security in vehicle design and operation.
ISO stands for the International Organization for Standardization. It is an independent, non-governmental international body that develops and publishes standards to ensure the quality, safety, efficiency, and interoperability of products, services, and systems across a wide range of industries.
