The automotive industry is rapidly evolving, driven by advanced technologies and connectivity. However, this progress also brings new challenges, particularly in addressing cybersecurity threats to vehicles. To tackle these issues, ISO and SAE jointly developed ISO/SAE 21434 in 2021, establishing it as the standard for automotive cybersecurity. In this blog, we explore the specific impacts of ISO/SAE 21434 on the automotive industry.
ISO/SAE 21434 requires the management of automotive cybersecurity across the entire product lifecycle, from design to disposal. This standard encourages automakers and suppliers to move away from fragmented security approaches and adopt systematic, process-oriented strategies. By integrating cybersecurity requirements early in the development phase, this shift reduces costs and risks that may arise after a product’s launch, while fostering a culture of security throughout the organization. Furthermore, the standard mandates all partners in the multi-layered supply chain to adhere to standardized processes, thereby enhancing security across the supply chain and improving transparency in contracts and collaborations.
ISO/SAE 21434 is closely aligned with new regulations such as UNECE WP.29 R155 and R156 in the European Union, providing a technical and organizational framework for compliance. This enables automakers and suppliers to maintain and strengthen their competitiveness in the global market. Additionally, the standard requires risk assessment and analysis of systems to identify potential threats proactively and establish mitigation strategies. This approach systematically reduces cybersecurity vulnerabilities during product development, enhancing customer trust and improving brand reputation.
Moreover, ISO/SAE 21434 views automotive cybersecurity as an organization-wide responsibility rather than limiting it to specific departments. This perspective fosters an environment where software engineers, hardware designers, legal teams, and executives collaborate. Consequently, the need for cybersecurity education and skill development increases, promoting interdepartmental communication and cooperation. At the same time, the standard lays the groundwork for creating new business opportunities. Products enhanced with robust security through ISO/SAE 21434 offer greater trust to consumers and open doors to new markets, such as data-driven services. Additionally, this evolution is likely to drive demand for automotive cybersecurity consulting, evaluation, and certification services.
In conclusion, ISO/SAE 21434 is a crucial framework that empowers the automotive industry to effectively address current and future cybersecurity threats, comply with regulatory requirements, and secure a competitive edge in the global market. Automotive cybersecurity is no longer just a technical issue but a key component of business success, and the significance of ISO/SAE 21434 will only continue to grow.
