5 Industrial Control Systems
Industrial control systems used to monitor and remotely control critical industrial processes SCADA systems Distributed Control Systems (DCS) Programmable Logic Controllers (PLC) Highly distributed Geographically separated assets Centralized data acquisition and control are critical Oil and gas pipelines Electrical power grids Railway transportation systems NIST Special Publication focuses on Security for Industrial Control Systems. It considers SCADA systems to be a subset of ICS. The other books focus on SCADA but acknowledge the other components DCS and PLC. Last bullet emphasizes the need for public and private sector cooperation

6 SCADA System Supervisory Control And Data Acquisition (SCADA) – An industrial measurement and control system. SCADA elements are: Central device Central Master Station – Supervisory system, gathering data on the process and sending action commands. Remote devices Programmable Logic Controller (PLC) and Remote Terminal Unit (RTU) – Connecting to sensors in the process, converting sensor signals to digital data and sending digital data to the supervisory system. Intelligent Electronic Devices (IED) – Microprocessor based controller which monitor and perform proactive functions. Designed to support substation automation functions.
