ISO/SAE 21434:2021 Automotive Cybersecurity

Overview of Automotive Cybersecurity (ISO/SAE 21434:2021)

Automotive cybersecurity provides end-to-end security that is built around the paradigm of defense-in-depth, a core pillar of the cybersecurity concept. Every part of the system must be carefully inspected and verified for security threats. Cybersecurity has become an essential component for both the supply chain segment and OEMs.

Connected vehicles are on the rise and more connectivity poses a greater threat to security. Cybersecurity is a huge concern for automakers and OEMs are no longer relying on suppliers to resolve their security concerns, they are instead opting for other viable solutions. The automotive industry is facing huge cybersecurity challenges, especially as they move towards a more specific electrical and autonomous vehicle realms. Though the concept of artificial intelligence and machine learning are playing an important role in new product development, the cybersecurity concerns involving these technologies still looms at large.

Application of ISO 21434

The automotive world is currently undergoing fundamental changes emphasizing the development and deployment of electrical vehicles (EVs) and automated vehicles (AVs). The most fundamental design requirements for EVs and AVs include safety and cybersecurity. In order to mitigate security risks and provide better design, making use of cybersecurity concepts in the automotive industry is of paramount importance. SAE J3061 and ISO/SAE 21434:2021 define and guide how to keep Autonomous Cars and Electric Cars safe from potentially being hacked. The industry is making use of the National Institute of Standards and Technology (NIST) Cybersecurity Framework to proactively monitor the challenges of vehicle cybersecurity and prioritize ways to curb associated risks. The industry is also utilizing cybersecurity cybersecurity professionals and firms for balanced and robust security solutions.

Benefits of ISO/SAE 21434

The vulnerabilities, threats, and challenges that come along are to be critically identified for a cyber-safe automotive environment. Security by design and state-of-the-art security countermeasures are to be effectively implemented to overcome cyber vulnerabilities.

In today’s world, implementing an effective cybersecurity policy is a challenging scenario as we have numerous connected devices, and hackers are increasingly fraught with danger. It becomes highly imperative to protect your product and data from cyber-crime.
