Ethernet Protection by Argus is an Intrusion Detection and Prevention System (IDPS) for in-vehicle Ethernet networks. It provides network monitoring, threat detection, and attack prevention capabilities. Ethernet Protection can be integrated into an ECU as an AUTOSAR firewall or a library, or embedded in switch firmware like EB zoneo SwitchCore Shield. Ethernet Protection is designed to help manufacturers balance the opportunities offered by in-vehicle Ethernet with necessary cyber security controls, supporting vehicle homologation and risk management.
