Modern cars use a high integration architecture with a smaller amount of powerful Electronic Control Units (ECUs). They easily accommodate more than 150 different services and are developed by more than 1000 developers in dozens of companies across the world. Ensuring security in such an environment is a challenge in multiple dimensions: Attack surface, overall system complexity and communication.

In this talk, I want to share our insights from building three generations of Yocto-based infotainment systems. How do we ensure basics such as the least privilege principle and privilege separation? What is our approach to trusted computing with secure boot and dm-verity? What are our lessons learned to enable SELinux on this large scale? Which best-practices do we have so that the system can be developed, tested and debugged in a (security) configuration that is close to the final product?

Furthermore, I would like to give positive examples how a good open-source ecosystem can support our cause of building secure embedded Linux systems as well as some impulses which improvements could help us a lot.
