A Remote Terminal Unit (RTU) is a specialized electronic device used in industrial control systems, particularly in sectors like utilities, energy, and water management. RTUs collect data from sensors and field devices, such as temperature or pressure sensors, and transmit this data to a central supervisory system, often via secure communication channels. They can also receive commands from the central system to control actuators or other devices in the field. RTUs are designed to operate in remote or harsh environments and are critical for real-time monitoring and control of distributed assets. In cybersecurity, RTUs are significant because they can be potential targets for cyberattacks, which may disrupt essential services.
