Industrial control systems (ICS) and operational technology (OT) are being thrust into the future by enabling technologies and transformative waves of innovation such as industry 4.0, IIoT, and 5G, which promise to bring major benefits in the form of increased productivity, safety, and operational efficiency. Modern industrial corporations will need to evaluate the many technology benefits on offer and determine an acceptable risk posture for their company if and when they ride one or all of these waves. With each transformation comes cybersecurity risks, including an increase in the potential attack surface and a plethora of new attack vectors for cybercriminals to exploit.
