Abstract
Operational technology (OT) is hardware and software that detects or causes a change through the direct monitoring and/or control of physical devices, processes and events in the enterprise. OT is common in industrial control systems (ICS), such as distributed control systems (DCSs) and supervisory control and data acquisition (SCADA) systems (see Figure 8.1). In the world of critical infrastructure, OT may be used to control power stations or public transportation. As this technology advances and converges with networked technology, the need for OT security is growing exponentially. Figure 8.1
