Understanding Automotive Cybersecurity Standards: Driving Towards a Secure Future

The automotive industry faces a challenge in ensuring the safety and security of interconnected, autonomous systems.

According to Upstream’s report, the global automotive cybersecurity market was valued at $7.23 billion in 2021 and is projected to reach $32.41 billion by 2030, with a CAGR of 16.6%. This growth highlights the need for more robust automotive cybersecurity standards in the automotive sector to outline requirements for managing cyber threats. 

This ISMS Connect guide explores four automotive cybersecurity standards and emphasizes their crucial role in protecting vehicles from evolving cyber threats. Whether you’re a cybersecurity professional, an industry insider, or a regulatory authority, this guide will equip you to navigate this domain confidently.

Let’s get started.

What Are Automotive Cybersecurity Standards?

Automotive cybersecurity standards refer to guidelines and requirements established to ensure the security and protection of vehicles against cyber threats. 

These standards outline the best practices, technical specifications, and protocols that automotive manufacturers and suppliers should follow to safeguard vehicles and their associated systems from potential cyber-attacks. Adhering to these standards helps enhance vehicles' overall cybersecurity posture and ensures drivers' and passengers' safety and privacy.

ISMS Connect is a community that helps SMBs get certified in information security management without high costs or consultants. We break down the often complex topic of information security management for SMBs and help them get certified by providing templates, guides, and help from consultants to get ready for certification by themselves.

How Automotive Cybersecurity Standards Can Benefit You

Protects Your Vehicle from Cyber Attacks

The increased connectivity of vehicles has led to a rise in cyber threats. According to a report by Upstream Security, there was a 99% increase in automotive cyber attacks in 2020. 

Automotive cybersecurity standards provide guidelines for identifying vulnerabilities and implementing security measures to prevent unauthorized access. This can significantly mitigate the risk of potential cyber-attacks.

Ensures Compliance with Regulations

Regulatory bodies around the world are recognizing the importance of automotive cybersecurity. For instance, the UNECE (United Nations Economic Commission for Europe) has introduced the World Forum for Harmonization of Vehicle Regulations (WP.29), which includes regulations related to cybersecurity and software updates for vehicles. 

Non-compliance can result in heavy fines. Under the General Data Protection Regulation (GDPR) in the EU, companies could face fines of up to 4% of their global annual turnover for data breaches.

Improves Customer Trust

Consumer perception is crucial in the automotive industry. A survey conducted by Deloitte found that 30% of respondents are “very” concerned about the security of connected vehicles. 

By adhering to recognized cybersecurity standards, automotive companies can demonstrate their commitment to safeguarding customer data and privacy, thereby improving consumer trust.

Reduces Costs

The cost of addressing cybersecurity breaches can be substantial. According to a study by the Ponemon Institute, the average cost of a data breach in the automotive industry was $4.35 million in 2023. Following cybersecurity standards like ISO/SAE 21434 during the development and manufacturing processes can help identify vulnerabilities early on, reducing the likelihood of costly security breaches.

Enhances Retention

Reputation is a valuable asset for any company. Implementing cybersecurity standards showcases a company's dedication to protecting not only their products but also their customers. According to the Cisco 2022 Consumer Privacy Survey, 37% of customers have discontinued their use of a company or service due to concerns about their data practices. 

Automotive Cybersecurity Standards

1. TISAX®

TISAX® (Trusted Information Security Assessment Exchange) is an automotive-grade cybersecurity assessment process developed by the German Association of the Automotive Industry. It facilitates exchange and comparison of information security standards between automotive suppliers and their customers—and it’s crucial to the security of cars and trucks on the road.

At ISMS Connect, we help SMBs simplify the complicated language and requirements of TISAX® through step-by-step guides, on-demand expert support, and comprehensive documentation. This helps SMBs achieve compliance quicker and with more confidence in their ISMSs.

2. ISO®/SAE 21434

ISO®/SAE 21434 is of utmost importance to security and compliance professionals as it offers comprehensive guidelines for identifying vulnerabilities and implementing effective security measures in vehicles. For these professionals, the standard provides a clear framework to manage cybersecurity risks across the entire lifecycle of a vehicle. 

This includes crucial phases like design, production, operation, maintenance, and decommissioning. Understanding and adhering to ISO®/SAE 21434 equips professionals with the tools to establish robust cybersecurity practices aligned with industry best practices and regulatory requirements.

2. UNECE WP.29 Regulation No. 155

UNECE WP.29 Regulation No. 155 is a new regulation on cybersecurity and over-the-air software updates. It is designed to ensure that vehicles are secure and that they can receive software updates over the air. This regulation directly impacts security and compliance professionals by addressing the rapidly evolving landscape of vehicle cybersecurity. In an era where vehicles are frequently connected to external networks, ensuring their security is paramount. 

This regulation emphasizes the security of over-the-air software updates, a critical component of modern vehicles. Professionals in security and compliance roles need to comprehend this standard to ensure their organizations comply with regulations and safeguard vehicles against cyber threats and unauthorized access.

3. SAE J3061

SAE J3061 is a guideline for the cybersecurity engineering of vehicles. It provides guidance on managing cybersecurity risks throughout a vehicle's entire product lifecycle. SAE J3061 provides cybersecurity engineering guidelines specific to vehicles. It is a practical resource for security professionals, offering insights into managing cybersecurity risks throughout the vehicle's lifecycle. 

For security and compliance professionals, this guideline acts as a roadmap for integrating cybersecurity into every aspect of vehicle development and operation. From the initial design stages to ongoing maintenance, understanding and implementing SAE J3061 ensures a consistent and robust approach to cybersecurity.

4. NIST SP 800-183

NIST SP 800-183 provides guidelines for cybersecurity for the Internet of Things (IoT). It guides how to manage cybersecurity risks in IoT devices. While not exclusive to the automotive sector, NIST SP 800-183 remains valuable to security and compliance professionals dealing with IoT devices within vehicles. 

Modern vehicles are IoT devices on wheels, integrating various connected systems. Professionals in the automotive industry need to consider the broader IoT security landscape. Understanding NIST SP 800-183 aids in effectively managing cybersecurity risks within these complex interconnected ecosystems.

Navigating the intricacies of information security management can be daunting—particularly for SMBs. That's where ISMS Connect steps in, offering an accessible combination of guides, templates, and expert advice.
