Operational technology (OT) represents systems that are used to monitor and manage the manufacturing equipment or industrial process assets of an organization. OT is a term developed to differentiate it from IT, which represents the information technology assets of an organization. OT is closely related to ICS (industrial control systems) and SCADA (supervisory control and data acquisition systems).
Industrial control systems (ICS) are often managed via a Supervisory Control and Data Acquisition (SCADA) systems that provides a graphical user interface for operators to easily observe the status of a system, receive any alarms indicating out-of-band operation, or to enter system adjustments to manage the process under control. Supervisory Control and Data Acquisition (SCADA) systems display the process under control and provide access to control functions.
