What is a firewall in a car?

A firewall in a car is a security measure that is designed to protect the car’s electronic systems and data from unauthorized access and cyber-attacks. It is a hardware or software-based system that serves as a barrier between the car’s internal network and the outside world.

The firewall in a car monitors and filters all incoming and outgoing traffic from the car’s network and blocks any suspicious or malicious traffic. It also tracks all network activities and generates alerts in case of any security breaches or anomalies.

Some modern cars have integrated firewalls as part of their infotainment systems. These firewalls can protect the car’s electronic systems from hacking and unauthorized access to sensitive data. However, older cars may not have a built-in firewall, but there are aftermarket devices that drivers can install to protect their vehicles.

In summary, a firewall in a car is an essential security measure that protects the car’s electronic systems and data from cyber-attacks and unauthorized access.
