Industrial control systems (ICS) refers to a variety of components and network infrastructure components used to control industrial processes or equipment to operate and automate industrial operations. Key functions of ICS include programmable logic controllers (PLCs), distributed control systems (DCS), and supervisory control systems (SCADAs). ICS provides advantages such as enhanced efficiency, increased productivity, reduced downtime, improved safety and better data sharing. With the rise of Industry 4.0 and digital transformation initiatives across industries, the adoption of ICS has increased significantly in the recent years.
