Automobile manufacturing is a vital element of the U.S. critical infrastructure. Accordingly, its operation and technologies must be protected. At the same time, the industry's distinctive ecosystem imposes unique and specialized demands on the cybersecurity process. So, automobile manufacturers must implement and utilize specially tailored cybersecurity best practices. New international regulations further reinforce the fundamental importance of compliance with training and education requirements. The Automotive Cybersecurity Training (ACT) Program satisfies all these conditions.The ACT Program centers on a well-defined and commonly accepted set of practices to conceptualize, design, implement, and sustain practical automotive cybersecurity solutions. The Auto-ISAC and the National Highway Traffic Safety Administration (NHTSA) have supported the development of that content. Thus, it is the most authoritative possible view of industry practice. In addition, ACT program education satisfies the UNECE R155 requirement for formal cybersecurity training, which allows automotive organizations to comply with ISO 21434, Clause Five stipulations.
