1. A system comprising: a reprogrammable network-routing device connected to a physical supervisory control and data acquisition (SCADA) controller and two or more intelligent-electronic devices (IEDs), the physical SCADA controller and the IEDs being members of an operational technology (OT) network; a fault-monitoring module configured to tap into a port of the reprogrammable network-routing device to detect a failure of the physical SCADA controller; and a network-manager module configured to: decouple the physical SCADA controller from the IEDs by reprogramming the reprogrammable network-routing device; and control the reprogrammable network-routing device such that bidirectional communication between the IEDs and a controller module is enabled.
