Automotive Cybersecurity Measures in ECU Production

Modern vehicles use a network of Electrical Control Units (ECUs) that transmit over 2500 signals. The production of these ECUs is fraught with cybersecurity challenges that can lead to significant vulnerabilities, which pose risks not only to the suppliers but also to Original Equipment Manufacturers (OEMs) and end users. The automotive industry increasingly relies on sophisticated electronic systems but there is a lack of standardized approach to ensure robust cybersecurity measures during ECU production. It is imperative to establish effective safeguards against potential threats to ensure vehicle and passenger safety. This paper proposes a comprehensive approach to enhancing cybersecurity in ECU production. Key measures include the activation of cybersecurity protections in series production units, secure flashing and dump processes, effective plant password management, and securing the JTAG port to prevent unauthorized access. By implementing these measures, suppliers can significantly reduce the risk of security breaches during the production process. The value of this paper lies in its potential to standardize and recommend essential cybersecurity practices within existing frameworks. By adhering to these proposed processes, suppliers can uniformly enhance the security in ECU production, thereby minimizing vulnerabilities. This uniformity not only benefits the suppliers but also ensures a higher level of protection for OEMs and end users. The recommendations provided in this paper aim to contribute to the development of robust cybersecurity standards in the automotive industry, fostering a safer and more secure production environment. The study is based on current and existing cybersecurity implementations at the supplier side during the ECU production process. The findings and recommendations are derived from practical experiences and observations, aiming to provide actionable insights. This paper is at the stage of proposing these recommendations for inclusion in available cybersecurity standards, with the goal of achieving widespread adoption across the industry.
