A Distributed Control System (DCS) uses distributed controllers for real-time industrial process control, requiring OT-specific security.
Distributed Control System (DCS) Definition: A Distributed Control System (DCS) uses distributed controllers for real-time industrial process control, requiring OT-specific security.
A Distributed Control System (DCS) is an industrial control architecture in which controllers are spread across a plant or process rather than centralized, coordinating continuous operations such as refining, power generation, and chemical processing. DCS deployments emphasize high availability and tight, real-time control loops within a facility, distinguishing them from the geographically dispersed monitoring focus of SCADA systems. Securing a DCS requires OT-specific segmentation, since legacy protocols often lack authentication.
