Ethernet & IP @ Automotive Technology Day

Tech Paper

Ethernet Security: How Effective Is It?

On September 19-20, Garrett Motion will be present at the Ethernet & IP Automotive Technology Day in Sao Paulo, Brazil, co-presenting with NXP a new tech paper in the Safety and Security panel.

In this presentation, we use automotive use cases and their typical implementation to build a framework to understand what the security mechanisms are within these cases and then try to quantify their effectiveness. We then derive a general partitioning of NIDPS functionality which is implemented in a typical Ethernet switch core and the functionality that might have to be implemented in an application or firmware running on an internal or external host processor. Finally, we look at a subjective assessment of features that such devices need and comment on their effectiveness. We then provide steps to make the device more effective.

Review IEEE Agenda

Intrusion detection systems

3 key takeaways

  • New and evolving network architectures in the vehicles significantly increase the attack surfaces
  • Exposure to Securing interfaces, Domain isolation, securing infrastructure and securing networks
  • Securing networks with IDPS and various deployment methods


Cybersecurity Solutions

Nearly all cars manufactured today are connected. Although connected vehicles promise improved performance, greater safety and access to more flexible and tailored mobility solutions, they are also attractive targets for cyber-attacks with exponential attack surfaces. In a recent survey conducted by Capgemini, 68% of customers identified cyber protection as a key decision factor when buying a car.

Garrett Motion’s expertise combines nearly 70 years of Tier 1 automotive technology leadership with a unique aerospace and industrial software heritage. Our cybersecurity solutions are tailored to the automotive product development process and promote productivity and agility, while considering relevant standards in their design.
