We generally do not allow product presentations at S4, but occasionally there is a technology that is novel or potentially important that we make an exception. For example, we had Kaspersky present on their ICS operating system at S4x15.

A second exception was made for Carlos Aguayo Gonzalez of PFP Cybersecurity to present the idea of using Power Fingerprinting to identify changes in PLC or RTU logic or firmware.


I won’t attempt to summarize the technical details; watch the video. It includes a demo of the technology.

However it is interesting that the Power Fingerprinting sensor is in fact not connected to the device it is monitoring. Hello air gap. It also is a potential tool for addressing the supply chain problem.
