Host Protection by PlaxidityX is a host-based Intrusion Detection and Prevention System (IDPS) designed for automotive electronic control units (ECUs) running on POSIX-based operating systems such as Linux, Android, and Adaptive AUTOSAR. The solution provides real-time detection, protection, logging, and fail-safe capabilities to address the increasing cyber risks associated with connected vehicle components like infotainment, telemetry, and driver assistance systems. It supports compliance with automotive cybersecurity standards (e.g., ISO/SAE 21434, UN R155), and can be enabled, disabled, or adjusted throughout the vehicle lifecycle. Host Protection validates the integrity and authenticity of executables at boot and during runtime, hardens the operating system, and provides a standardized interface for security event notifications. The system is engineered for minimal impact on ECU resources and is suitable for integration into both prototype and series production environments.
