What Is Cyber Security in The Automotive Industry?

Cybersecurity in the automotive industry refers to the application of processes, practices, and technologies to ensure vehicles and their associated systems are protected from cyber threats. Modern vehicles are increasingly connected, with more software and internet enabled features – including infotainment systems, navigation, and even autonomous vehicles.

Connectivity exposes vehicles to threats that hackers can compromise, meaning a breach in vehicle safety, risk of confidential data being disclosed, and system integrity being put at risk. Automotive cybersecurity ensures that systems are not able to be compromised and that drivers and passengers remain safe.

What Is The ISO for Cybersecurity in Automotive?

The automobile sector ISO standard for cybersecurity is ISO/SAE 21434. This standard provides guidelines for managing cybersecurity risks throughout the lifecycle of a vehicle, including design, development, production, operation, and decommissioning. The ISO standard is risk-based. Auto manufacturers and suppliers need to identify cyber threats to product and eventually be able to assess impact. Then they must target cyber threats in order to have mitigation information that protects vehicle systems and data.

Which Industry Needs Cyber Security the Most?

While many industries rely on cybersecurity, some are more vulnerable due to their reliance on connected systems and sensitive data. Critical industries, such as healthcare, finance, defense, and other industries have been established among those industries most in need of robust cybersecurity.

Security challenges for the automotive sector are distinctly unique because they now rely on software, autonomous features, and network communication in order to operate the vehicle, putting the industry within the unique industry segment that utilizes/relies on connected vehicle systems and organization-wide connected systems for daily business activities, and that poses cybersecurity risk.

What Is the Standard for Automotive Cyber Security Industry?

The leading standard for automotive cybersecurity industry is ISO/SAE 21434, published in 2021, which provides an overall framework for how to manage cybersecurity throughout the lifecycle of a vehicle. Also, The United Nations Economic Commission for Europe (UNECE) have established UNECE WP.29 frameworks. This framework includes required cybersecurity management system (CSMS) elements for vehicle manufacturers. Both of these frameworks hope to enable automotive systems that are secured from threats as they evolve and promote consumer confidence in connected and automated vehicles.
