In light of recent incidents that impacted both information technology (IT) and operational technology (OT) environments, organizations are increasingly evaluating the risks associated with growing IT/OT convergence.

IT environments include cloud computing, internal and outsourced Internet applications, and business and technical systems used across the organization, such as for e-commerce, human resources, and engineering. OT environments includes both nonindustrial and industrial Internet of Things (IoT); industrial control systems (ICS) such as continuous and batch DCS, PLC, and SCADA controllers; and industrial automation systems for discrete manufacturing and robotics, building management systems such as HVAC control, electrical distribution, and medical devices.
