Strategies to secure connected cars with firewalls

Vehicle network security requirements are becoming more stringent as vehicle systems face hostile adversaries through various entry points. White-hat hackers have demonstrated gaining remote access to dashboard functions and transmissions of connected vehicles. In response to the posed threats, governments around the globe are legislating liabilities for self-driving vehicles (the U.S. SELF DRIVE act of 2017 is an example). That makes a firewall a vital component of a multilayered approach to vehicle security and overall vehicle safety and reliability.

Firewalling the threats with multi-layered security

Cyberattacks on cars begin with hackers finding a way inside the car – defining the attack surface. The next step is compromising an electronic control unit (ECU) that can be exploited and compromised to access certain functions. Protecting connected cars requires a multi-layered security approach, and a firewall is a vital component. The automotive industry must prove itself trustworthy enough for humans to trust connected cars. Security is not a competitive offering – it is required for a connected car to work, and the firewall remains a vital component of a multilayer security approach.

In the paper, you will learn about:

  • Automotive software and cybersecurity threats and regulations
  • Why a multi-layered security approach helps deter the threats
  • Considerations on how to design the firewall
