The Evolving Threat Landscape
Modern vehicles represent a complex convergence of mechanical engineering and sophisticated software, creating a broad and dynamic attack surface. The integration of telematics units, cellular modems, and infotainment systems has expanded potential entry points for malicious actors beyond physical access.
Remote attack vectors now target vehicle-to-everything (V2X) communication protocols and backend servers, while in-vehicle networks like Controller Area Network (CAN), Local Interconnect Network (LIN), and automotive Ethernet require robust segmentation to limit lateral movement. The industry's shift towards over-the-air updates, while beneficial, introduces new lifecycle management challenges for security patches.
For a deeper regulatory perspective, readers may refer to the official UNECE R155 documentation and the ISO/SAE 21434 standard.
