Automotive cybersecurity is recognized as an essential element for vehicle safety. To ensure automotive cybersecurity, appropriate infrastructure is required for the operation and management of cybersecurity after applying cybersecurity measures to electronic components. This includes activating encryption keys at the final stage of production, enabling online services, continuously updating security policies and detecting security risks. By operating a cybersecurity infrastructure, companies can proactively respond to newly discovered security threats and vulnerabilities after the production of electronic components, thereby maintaining a certain level of automotive cybersecurity. This presentation examines the necessity and role of the infrastructure required for automotive cybersecurity operations.
