Abstract
A cybersecurity monitoring device includes an electromagnetic (EM) field sensor for sensing a modulated signal transmitted on an electrical cable which encodes information by varying properties of a periodic waveform. The cybersecurity monitoring device includes a processor and a memory storing a data decoding program including protocol information for identifying a plurality of different communication protocols. The cybersecurity monitoring device is adapted for use without electrical contact in proximity to the cable so that the EM field sensor detects an EM field emanating from the modulated. The data decoding program responsive to detecting the EM field performs signal conditioning including digitizing the sensed modulated signal to provide a digitized signal, decoding the digitized signal using the protocol information used by the modulated signal to generate a decoded signal data, and reporting the decoded signal data or tampering determined from the decoded signal data to a remotely located device or system.
