OEMs sometimes specify their security requirements in an incomplete or vague way, but that certainly doesn’t mean that Tier 1 automotive suppliers (Tier 1s) should neglect responsibility for cybersecurity. By adopting a proactive approach to the topic, it becomes possible to add value for the consumer, the OEM, and the Tier 1, as well as mitigate risk. It’s better for everyone if automotive suppliers take action to ensure that security is built into products, collaborating as far as possible with both OEMs and other suppliers.
