Cybersecurity Standards for Automotive: What are They and Why are They Important?

Vehicles are becoming increasingly connected and autonomous, which is why cybersecurity has become a pressing concern for the automotive industry. A lone cybersecurity breach can end up leading to substantial financial losses, damage to brand reputation, and even put lives at risk. To tackle this problem, multiple organizations and regulatory bodies have developed cybersecurity standards for the automotive industry. In this article, we will take a look at some of the key cybersecurity standards that are relevant to the automotive industry.

What are Cybersecurity Standards for Automotive

Cybersecurity standards are a set of guidelines and best practices that have been designed to help identify, assess, and manage cybersecurity risks that are associated with connected vehicles. They offer a framework for designing, testing, and deploying secure systems that can protect against cybersecurity threats and maintain customer trust.

The most popular and widely recognized cybersecurity standards for the automotive industry include ISO/SAE 21434, SAE J3061, NIST Cybersecurity Framework, and Automotive Cybersecurity Best Practices. These standards give guidance for the identification and assessment of cybersecurity risks, implementation of effective security measures, and maintenance of compliance with regulations.

Why Do We Need Cybersecurity Standards for Automotive

Cybersecurity standards in the automotive industry are essential to make sure that drivers and passengers remain safe and secure. Connected and automotive vehicles are reliant on complex software systems that can be vulnerable to cyber attacks. Cybersecurity standards for automotive ensure that these systems are designed, tested, and deployed with appropriate security measures to defend against cyber threats.

Cybersecurity standards not only protect drivers and passengers, but also protect personal data and corporate reputation. Connected vehicles collect and transmit large amounts of personal data which is extremely valuable to cyber criminals. Good cybersecurity measures are essential to protect this data from unauthorized access or disclosure. Compliance with regulations related to cybersecurity is also required, and cybersecurity standards provide a framework to meet these requirements.

ISO/SAE 21434:2020 — Road vehicles — Cybersecurity engineering

The International Organization for Standardization (ISO) and the Society of Automotive Engineers (SAE) developed the ISO/SAE 21434 standard to give a framework for cybersecurity in road vehicles. The standard specifies a risk-based approach to cybersecurity, and it offers guidelines for identifying, assessing, and managing cybersecurity risks throughout the vehicle’s lifecycle.

The ISO/SAE 21434 standard is applicable to all road vehicles, including passenger cars, trucks, buses, and motorcycles. It takes into account all aspects of cybersecurity engineering, including cybersecurity management, security requirements, and security verification and validation.

One of the main requirements of the ISO/SAE 21434 standard is that vehicle manufacturers need to establish a cybersecurity management process that encompasses the identification and assessment of cybersecurity risks, the development of cybersecurity objectives and strategies, and the implementation of cybersecurity measures. This standard also needs vehicle manufacturers to establish a process for security requirements engineering that ensures that security requirements are pinpointed, analyzed, and documented.

ISO 27001 — Information security management

The ISO 27001 is a standard that is widely recognized for information security management. Although it is not specific to the automotive industry, it offers a framework for managing information security risks, which is also relevant to the automotive industry.

This standard is based on a risk management approach and provides a systematic framework to establish, implement, maintain, and continually improve an information security management system. It covers every aspect of information security management, including but not limited to risk assessment, security controls, and security monitoring and review.

A key requirement of the ISO 27001 standard is that organizations must establish and maintain an information security management system that is tailored to their specific needs and objectives. This standard offers a framework for identifying and assessing information security risks, selecting and implementing appropriate security controls, and monitoring and reviewing the effectiveness of these controls.

NIST Cybersecurity Framework

The National Institute of Standards and Technology (NIST) Cybersecurity Framework is a voluntary framework that provides a set of guidelines and best practices to improve cybersecurity risk management. Though it is not specific to the automotive industry, the framework is largely recognized and applicable to a wide range of industries, including automotive.

The NIST Cybersecurity Framework offers a framework for organizations to identify, assess, and manage cybersecurity risks. It includes 5 core functions: Identify, Protect, Detect, Respond, and Recover. These functions provide a comprehensive approach to cybersecurity risk management, from identifying risks to recovering from cybersecurity incidents.

One of the most important advantages of the NIST Cybersecurity Framework is that it is flexible and can be adapted to fit the specific needs of an organization. It provides a common language for discussing cybersecurity risks and provides a framework for developing a cybersecurity risk management program that is tailored to meet the specific needs of an organization.

Conclusion

In conclusion, the automotive industry requires cybersecurity standards to protect against cyber threats and maintain the safety and security of drivers and passengers. These standards provide a framework for designing, testing, and deploying secure systems that protect against cybersecurity threats and maintain the trust of customers. Compliance with these standards is necessary for ensuring the safety and security of connected and autonomous vehicles and protecting personal data and corporate reputation.
