Isolated Partitioning of Firmware Improves IoT Device Security

There are two methods for improving IoT device security: secure partitioning and secure coding. The latter seems to have gained favor, not only for cloud software, but also for IoT device firmware. This may be because there has not been an effective firmware partitioning solution for microcontroller-based devices using memory protection units (MPUs). We are …

Blocking USB Threats

Factory threats are escalating at a staggering rate. Honeywell has written a helpful report (Ref. 1) on how USB devices are being used to circumvent the air gap that protects most factories. This is becoming a serious industrial cybersecurity problem. One type of USB device is specifically designed to inject a trojan horse into a …
