What is the Auto Industry’s Cyber Security Standard?


Updated on:

It was a sunny day in June, and I was heading to an auto dealership. My friend had asked me to accompany him to pick up his brand new car. I was already aware of the potential security threats that surround modern cars. But as we were driving, something struck me. What if the dealership had not taken adequate measures to secure their systems? Could my friend’s new car be at risk of a cyber attack?

As we arrived at the dealership, my curiosity got the best of me, and I decided to investigate. What I found left me stunned. The dealership had almost no security measures in place to protect their systems from cyber threats. Customer information, including names, addresses, and financial details, were stored in databases that were susceptible to hacking. The car software update process was done over the internet and did not use any encryption or authentication measures.

This experience got me thinking about the auto industry’s cyber security standard. Was there a standard that all auto manufacturers and dealerships had to follow to ensure adequate cyber security measures were in place? The short answer is yes, there is.

In this article, I’m going to share with you what the auto industry’s cyber security standard is, how it came about, and why it’s crucial in today’s world. Buckle up – this is going to be an eye-opening ride.

    3. Implement access control measures: Control access to your automotive systems and data to limit the risk of a cyberattack. Implement strong password policies, multi-factor authentication, and role-based access control to ensure that only authorized personnel have access.

    4. Secure your network: Secure your automotive network by utilizing firewalls, intrusion detection and prevention systems, and other network security measures. This will help prevent unauthorized access to your systems and data.

    5. Invest in training: Educate your employees and stakeholders on the importance of cyber security in the automotive industry. Investing in training will raise awareness and ensure everyone is aware of the potential risks and how to protect against them.

    Introduction to Cyber Security in Automotive Industry

    As the automotive industry advances, an increasing number of vehicles are connected to various forms of technology such as GPS, smartphone integration, and Wi-Fi hotspots. These advances have made cars more efficient, convenient, and fun to drive. Still, they also come with cybersecurity risks that need to be addressed. Vehicle security breaches can compromise the safety of drivers and passengers, causing car accidents, theft, and injuries. Therefore, automotive cybersecurity is a crucial aspect of the automotive industry that needs to be taken seriously.

    Overview of ISO/SAE 21434 Standard for Cyber Security

    The ISO/SAE 21434 standard is the latest global standard for cybersecurity in the automotive industry. The collaboration between the International Organization for Standardization (ISO) and the Society of Automotive Engineers (SAE) resulted in the development of this standard to provide industry guidelines for creating secure automotive systems. ISO/SAE 21434 is a comprehensive, systematic approach to automotive cybersecurity that aims to provide a framework for developing secure automotive systems that can withstand potential cyber threats.

    Importance of Development Process in Automotive Cyber Security

    Developing a secure automotive system is critical for effective cybersecurity. That’s why the ISO/SAE 21434 standard emphasizes the development process. The standard recognizes the importance of ensuring that vehicle security considerations are taken into account at each stage of the development process. Developers must consider cybersecurity risks in everything from design to network maintenance, from software testing to production and maintenance.

    Guidelines for Risk Analysis in ISO/SAE 21434 Standard

    Risk analysis is a crucial component of ISO/SAE 21434 cybersecurity standard. The standard provides a structured approach to identify and evaluate cybersecurity risks systematically. It provides guidelines for risk assessment to identify any potential cybersecurity threats and vulnerabilities. The standard outlines how cybersecurity risks should be assessed, evaluated, and managed throughout the development process and after the system has been deployed. This includes identifying potential vulnerabilities, mapping system components, and assessing the system’s overall security posture.

    • Identification: identify the assets, threats, and vulnerabilities of the system.
    • Assessment: assess the likelihood and severity of risks to the system.
    • Management: plan, implement, and monitor security controls to minimize the identified risks.

    Specifications for Threat Analysis in ISO/SAE 21434 Standard

    ISO/SAE 21434 standard provides detailed specifications for threat analysis that should be considered during the development process. The standard emphasizes that threat analysis needs to be conducted throughout the development process to identify any new emerging threats. The specifications ensure that all potential threats are considered, including cyber threats such as unauthorized data access, potential for malware intrusion, and any possible misuse of vehicle technology. The following are some of the key specifications covered by the standard.

    • Asset Identification: Identify and inventory components and data within the vehicle system that are critical to the vehicle’s function and safety.
    • Threat Identification: Identify potential threat sources, motivations, capabilities, and attack vectors.
    • Control Analysis: Define security controls that address identified threats and evaluate their effectiveness.
    • Verification and Validation: Develop and perform verification and validation testing and evaluate the security results of these tests.
