What is firewall on car?

A firewall on a car refers to a component that acts like a digital barrier to protect the vehicle's electronics from unauthorized access and malicious attacks. The firewall blocks traffic from unauthorized sources and only allows authorized traffic to pass. It also prevents malware and viruses from entering the car's systems. A car's firewall is typically integrated with the vehicle's software control unit and hardware components and provides a secure environment for the car's electronic systems to operate. Firewall technology onboard a vehicle is essential for preventing remote interference, enhancing safety, and protecting personal data and information.
