Abstract
Systems and methods for providing access to historical data over a real-time tunnel are disclosed. The method provides a mechanism for secure communication between one or more historians. In an example, attack surfaces on historians in an industrial control system operational technology (OT) network and in an information technology (IT) networks are reduced and possibly entirely eliminated by tunneling through a DMZ (de-militarized zone) or “secured network”.
