Abstract: A system and a method for securing control systems for critical infrastructure, complex networks and/or industrial processing facilities. Aspects of the invention can include a proximity-based user identification device that generates a computer-readable identification of operators who are in proximity to a control device in the control system and an imaging device that captures a visual likeness of operators in proximity to the control device. A network sensor can read operation data from the control system. An overlay network can interconnect the proximity-based identification device, the imaging device, and the network sensor, and can interface to the control system without modifying the control system. Processing hardware can execute processor-implemented instructions to generate a correlation between at least a portion of the operation data and the control system, the computer-readable identification, and the visual likeness.
