The European Automobile Manufacturers’ Association (ACEA) and its members have identified six key principles to enhance the protection of connected and automated vehicles against cyber threats. These principles include cultivating a cybersecurity culture, adopting a cybersecurity life cycle for vehicle development, and assessing security functions through testing phases. The focus is on ensuring that adequate cybersecurity mechanisms are implemented and that cybersecurity risks are dealt with appropriately. The interfaces of connected vehicles present an opportunity for exploiting vulnerabilities, and attackers may compromise the user’s personal data, threaten the vehicle’s systems, or endanger passengers. By following these principles, ACEA and its members aim to keep cybersecurity risks for connected vehicles in check and promote the safe and secure use of these vehicles.
