SCADA

Supervisory Control and Data Acquisition (SCADA) systems consists of geographically scattered units (field devices) controlled using centralized data acquisition and control (control center) [Sto06]. They are usually highly distributed systems. Field devices could be controlling local operations such as valve operations, collecting sensor data, and monitoring for disaster conditions. The next figure shows the general architecture of a SCADA system. Examples for SCADA systems are electric power systems, oil and gas pipelines, water utilities, and any system that requires remote monitoring and control.
