Abstract

Supervisory Control and Data Acquisition (SCADA) systems, which are often used in several types of Essential Systems and Critical Infrastructures, depend on control devices such as Programmable Logic Controllers, Remote Terminal Units and Intelligent Electronic Devices. Such devices, which are deployed at the edge of the SCADA infrastructure, directly interface with the physical processes under control. They are often based on embedded systems with limited capabilities and exposed to significant security and safety-related risks, as demonstrated by past incidents such as Stuxnet. However, despite the recognized relevance of those edge devices, they usually lack monitoring mechanisms able to detect device anomalies and/or cyber-physical threats.
