Developed by the International Organization for Standardization (ISO) in conjunction with the Society of Automobile Engineers (SAE) International, the ISO/SAE 21434 standard was developed to help organizations define cybersecurity policies and manage risk. It is a demanding specification with 45 security categories, known as work products, each of which specifies a unique set of requirements that encompass all aspects of designing electrical and electronic systems for road vehicles, from ICs and software to firmware and libraries.

The ISO/SAE 21434 designation also confirms that a certified corporate cybersecurity management system is in place. This verifies that cybersecurity is a priority focus at the organization, from executive leadership to all organizational disciplines including the design, test, product, applications, marketing, quality, verification and validation teams. Stakeholders involved in the product lifecycle are required to complete cybersecurity training and meet designated qualifications. A Threat Analysis and Risk Assessment (TARA) methodology is also incorporated at multiple stages of the product lifecycle when devices will be integrated into automotive cybersecurity-related platforms.
