Implementing Automotive Cybersecurity in the Supply Chain

By Dr. Juan Pimental, Cybersecurity Principal Consultant, Omnex Inc.

Vehicles are becoming increasingly complex with many convenience, functional, performance, and safety features added constantly. Such complexity and multitude of features also introduce many attack surfaces enabling attackers reach vehicle assets and incur losses to stakeholders. Per the ISO/SAE 21434 standard, automotive cybersecurity is a condition in which assets are sufficiently protected against threat scenarios to electrical or electronic components of road vehicles and their functions.

To help implement automotive cybersecurity, a number of standards, guidelines, and government regulations have been developed in the last few years. Implementing appropriate cybersecurity standards is crucial for protecting a vehicle from attacks and mitigating cybersecurity risks in a manner that is commensurate with the threats and vulnerabilities.

The goal of this white paper is to discuss the implementation of cybersecurity from the view point of the three types of organizations in the vehicle supply chain: OEMs, Tier 1, and Tier 2, rather than the implementation of cybersecurity from the viewpoint of a single standard.
