Protect connected cars with a multilayered security approach and firewall configuration

Reading time: 33 minutes

Today’s vehicles are equipped with more software than the most sophisticated machines of our time. With the megatrends of connectivity, electrification, and autonomous driving, automotive software content has become even more relevant; software complexity and connectivity increase the vulnerability of automobiles to security threats. In response to the posed threats, governments worldwide are legislating liabilities for self-driving vehicles (the U.S. SELF DRIVE Act of 2017 is an example). The automotive industry must prove trustworthy enough for humans to trust connected cars.

In this white paper, discover how a firewall is a vital component of a multilayered approach to vehicle security as well as overall vehicle safety and reliability.

Drive vehicle security, safety, and reliability by firewalling security threats

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. The overall security policy must cover prevention at every level or at the level based on the use. A network layout with a firewall prevents the internal network from malicious data coming from the outside world. It also protects the outside world from potential malicious data generated inside the network. A firewall can secure a portion of the network inside the car, so if a specific ECU is compromised, it cannot exploit the weaknesses for the ECU within that secure portion of the network.

Download the white paper to discover multiple firewall designs considerations and learn why early detection, configurability, and standardization are critical to the final design consideration.
