ISO/SAE 21434: Cybersecurity Standard for the Automotive Industry

ISO/SAE 21434 is a cybersecurity standard for the automotive sector, focusing on safeguarding the electrical and electronic systems in vehicles. It offers a framework for managing cybersecurity risks throughout a vehicle's lifecycle, from design and development to production and decommissioning. The standard addresses the security challenges of modern vehicles, including connected and autonomous technologies. It highlights the importance of risk assessment, governance, threat detection, and continuous monitoring, promoting collaboration across the industry to protect vehicles and consumers from evolving cyber threats.

At digiALERT, we specialize in ISO/SAE 21434 compliance. Our services provide a comprehensive view of your automotive systems and their associated cybersecurity risks. We assess the system for potential vulnerabilities, identify and document the security controls in place, and provide detailed recommendations for improving cybersecurity measures. We begin by reviewing the system's architecture and components to identify common cybersecurity issues, such as insecure communication, software vulnerabilities, and inadequate encryption. We also assess the supply chain and third-party software for potential risks. Once vulnerabilities are identified, we offer detailed recommendations to mitigate these issues and enhance the overall cybersecurity of the system. Next, we review the security controls to ensure they are appropriately implemented and maintained throughout the vehicle lifecycle. This includes evaluating risk management processes, incident response plans, and software updates. We also ensure that the system complies with industry regulations and standards to meet ISO/SAE 21434 requirements, helping to safeguard your automotive systems from cyber threats.
