Industrial Control System (ICS) Security refers to the set of technologies, processes, and practices designed to protect industrial automation and control environments from cyber threats. These environments include Supervisory Control and Data Acquisition (SCADA) systems, Distributed Control Systems (DCS), and other operational technology (OT) assets that manage critical infrastructure and industrial processes. Core capabilities of ICS Security solutions include network segmentation, real-time monitoring of industrial protocols, anomaly detection, asset inventory, and incident response tailored to OT environments. These solutions address unique challenges such as legacy system vulnerabilities, limited downtime tolerance, and the need for specialized protocol support. Technical scope often extends to both IT and OT networks, requiring integration with existing industrial processes without disrupting operations. ICS Security is primarily used by organizations in sectors such as energy, manufacturing, utilities, and transportation, where the integrity and availability of industrial processes are essential. Security teams, OT engineers, and compliance officers rely on these solutions to mitigate risks specific to industrial environments, which differ from traditional IT security concerns due to the physical consequences of cyber incidents. Unlike general IT security, ICS Security focuses on the intersection of cyber and physical systems, emphasizing operational continuity and safety.
