Digital transformation (DX) is propelling organizations forward and accelerating the convergence of operational technology (OT) with information technology (IT). Note for the purposes of this paper that OT is synonymous with industrial control systems (ICS). OT-ICS environments perform supervisory management of cyber-physical processes in a production environment. They are composed of a variety of different kinds of software and hardware, including programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) systems, and human-machine interfaces (HMI).
