Case Study

Use Case: Drinking Water Chemical Level Management

This use case shows how a customer implemented operational procedures to ensure that the USB hardware keys required for OTfuse setup and reconfiguration were tracked using a physical log and stored in a cabinet which is monitored via a surveillance camera. The camera feed is recorded and also displayed in real time on a monitor in the control center, ensuring that a camera failure is immediately detected.

Upon final acceptance, the OTfuses were successfully protecting both modbus and ethernet/IP traffic such that only trusted sources were interacting via permitted methods with known critical PLCs and other assets. Any anomalous instructions to the injection pumps were flagged for immediate review and blocked from modifying pump behavior.
