Cybersecurity threats can easily bypass them, leaving the vehicle vulnerable to remote control and hacking by skilled attackers.

Protects User Information

Modern vehicles are no longer just modes of transportation—they’re data-rich machines, capturing and processing personal information. Vehicles store sensitive information, from location data to financial details. Robust cybersecurity measures are crucial to preventing unauthorized access to this data and protecting users from potential identity theft and privacy breaches.

Maintains Regulatory Compliance

To guarantee the well-being of drivers and passengers, governments and regulators are introducing regulations and guidelines that enforce minimum cybersecurity standards. Complying with these regulations is crucial for legal adherence and demonstrates an organization's dedication to protecting its customers and products.

How to Secure Automotive Cybersecurity Compliance

1. Understand Automotive Cybersecurity Regulations

In recent years, governments and regulatory bodies worldwide have recognized the critical importance of cybersecurity in the automotive sector. Standards such as ISO®/SAE 21434, UNECE R155, TISAX®, ISO® 27001, and others have been established to set minimum requirements for cybersecurity processes, testing, and risk management. 

Not sure where to start when it comes to TISAX® and ISO® 27001 compliance? ISMS Connect can help.
