Host Protection by Argus Cyber Security is an ECU Intrusion Detection and Prevention System designed for Posix-based ECUs running Linux, Android, and Adaptive AutoSAR software in vehicles. It reduces risk and drives compliance through detection, protection, logging, and fail-safe capabilities. Host Protection is specifically tailored for automotive-specific requirements such as AUTOSAR cyber security, addressing the increased risks faced by core vehicle components like infotainment, telemetry units, and driver assistance systems that are built on widely available POSIX operating systems. It aims to detect threats and prevent system intrusions in connected ECUs.
