VicOne ran its vehicle intrusion-detection engine on Sony's SPRESENSE board

VicOne, the Tokyo-based automotive cybersecurity subsidiary of Trend Micro, said on September 30 that it had implemented xCarbon, its intrusion detection and prevention system for edge devices, on SPRESENSE, the board computer for connected devices developed by Sony Semiconductor Solutions, and confirmed that the CAN message anomaly detection function ran correctly on it.

The company framed the exercise as a verification rather than a product. It said it would use the result to consider where else xCarbon might be deployed across edge devices, and described the work as part of extending security knowledge built in the vehicle sector into robots, drones and industrial equipment.

VicOne described xCarbon as a software-based system that can be embedded regardless of operating system or hardware, built in modules so that only the detection functions a device needs are configured, and able to scale from low-end microcontrollers to high-performance computers. It said the product carries more than 2,000 threat expert rules derived from its own automotive threat intelligence, covering CAN message anomaly detection, denial-of-service detection, container escape detection, an Ethernet firewall and host-based intrusion detection. VicOne also said it had begun offering Rthena, a runtime risk monitoring and protection platform built on xCarbon.

SPRESENSE carries six Arm Cortex-M4F cores with GNSS positioning and high-resolution audio, and is used in drones, smart speakers and monitoring equipment. VicOne chief executive Max Cheng said edge devices were gaining processing power and becoming targets at the same time.
