For the first time, I will be speaking at S4. It will be on process sensors and the lack of cyber security. Sensors require engineers (not just OT) to be part of the cyber security process. If you can’t trust your measurements, how can you be secure, reliable, safe, or your process be optimized? This is a real problem as there been many catastrophic failures because of sensor issues. The presentation will discuss some of these incidents as well as a possible monitoring solution. In order to know whether the sensor readings are correct and uncompromised, the monitoring must be done at the raw signal level BEFORE it becomes an Ethernet packet.
