This fall, the Department of Transportation's National Highway Traffic Safety Administration (NHTSA) issued proposed guidance on cybersecurity best practices for the automotive industry. The proposed cybersecurity guidance encourages manufacturers and designers of vehicle systems and software to prioritize vehicle cybersecurity by proactively adopting the non-binding guidance, which focuses on a layered approach to vehicle cybersecurity. This layered approach "reduces the probability of an attack's success and mitigates the ramifications of a potential unauthorized access." The guidance also recommends that stakeholders in the automotive industry implement a number of key changes, including making cybersecurity a priority throughout the entire life-cycle of the vehicle development process; allocating dedicated resources to addressing cybersecurity vulnerabilities; adopting a vulnerability reporting/disclosure program and incident response process to facilitate information-sharing; and considering penetration testing to detect cybersecurity vulnerabilities.
