Security is a fundamental requirement for today‘s and future EE-architectures. Depending on a thorough risk assessment of all sensor data flows, protections and resiliencies must be introduced from the lowest to the highest data rates.

The sheer complexity of the technology required to offer modern vehicles with old and new use cases would already present a formidable real-world challenge. Add to that an evolving and volatile regulative environment across global jurisdictions, the increasing sophistication of adversarial actors, and the ever-present and ever-increasing competitive cost pressure, it seems that providing adequate security is not going to become a straightforward mission any time soon.

What are some strategies that the industry could adopt? We make a case for risk-based, adequate protection mechanisms of the onboard networks that scale in line with employed technologies. Proprietary, and even some non-proprietary but single-source solutions expose integrators to long-term risks that must be considered already today.
