Operational Technology (OT) refers to the hardware and software systems that control and monitor physical devices and processes in industrial environments. Unlike traditional IT, which focuses on data processing and communication, OT deals with the real-world execution of operations such as machinery control, facility management, and industrial processes.

Key examples of OT systems include:

Physical Access Control Systems (PACS): Manages physical entry to facilities using technologies like keycards, biometric scanners, and video surveillance.
Supervisory Control and Data Acquisition (SCADA) Systems: Monitors and controls critical infrastructure processes, such as those in water treatment, oil and gas, and electricity distribution.
Programmable Logic Controllers (PLCs): Automates machinery or systems like HVAC in industrial settings, providing direct control over electromechanical processes.
Distributed Control Systems (DCS): Allows for the decentralized control of manufacturing processes, especially in complex plants or production lines.
Building Management Systems (BMS): Controls and monitors building services such as HVAC, lighting, and security.
Industrial Control Systems (ICS): Broadly encompasses systems used to control industrial processes, including those in chemical plants and power generation facilities.
CNC Machines (Computer Numerical Control): Automates manufacturing processes like cutting and drilling with precision.
Robotic Process Automation (RPA) in Manufacturing: Deploys robots to perform tasks such as assembly, packaging, and material handling.
Energy Management Systems (EMS): Optimizes the production and distribution of energy, such as in power plants.
Industrial IoT (IIoT) Devices: Smart sensors and connected devices that enhance efficiency by collecting data in real-time for industries like transportation and logistics.
Automated Guided Vehicles (AGVs): Transports goods autonomously in warehouses or factories.

These systems are crucial for managing and controlling physical operations, making OT a critical focus for security and governance, especially as OT environments increasingly converge with IT systems.

Industries That Leverage OT Technology

OT is foundational across a variety of industries where physical processes are essential to operations.

Some key sectors utilizing OT technology include:

Manufacturing: Automotive, electronics, aerospace, textiles, and more use OT to automate and control production lines.
Oil and Gas: From exploration and extraction to refining and distribution, OT systems monitor and manage key processes.
Mining: OT is integral to operations in coal, metals, and mineral extraction and processing.
Power Generation: Used in nuclear, thermal, hydroelectric, wind, and solar plants for process control and distribution.
Utilities: Essential for electricity, water, and natural gas distribution networks.
Pharmaceutical Manufacturing: OT systems ensure precision and compliance in drug production.
Food and Beverage Processing: Automation controls everything from ingredient processing to packaging.
Metals and Steel Production: OT governs complex smelting and rolling processes.
Shipping and Logistics: From automated warehousing to fleet management, OT drives efficiency.
Cement and Building Materials Manufacturing: Controls operations in material processing and distribution.
Healthcare: In hospitals and medical device manufacturing, OT helps manage critical infrastructure.
Transportation and Railways: Governs metro systems, signaling, and control infrastructure.
Ports and Maritime: Controls cargo handling, ship operations, and logistics.
Aviation: Manages airport operations, air traffic control, and baggage handling systems.
Telecommunications: Operates network infrastructure, improving reliability and security.
Defense and Military: From operational control to automated weapon systems, OT is crucial for defense technology.
Smart Cities: Monitors and manages urban infrastructure, from traffic control to public utilities.
Environmental Monitoring: Tracks and manages systems such as wastewater treatment and air quality control.
Retail and Warehousing: Uses automation for inventory management, distribution, and robotics.
Renewable Energy: Manages operations in wind farms, solar power plants, and geothermal facilities.
Aquaculture: Automates systems for efficient fish farming and resource management.

Why OT Requires Identity and Access Governance

Industrial systems operate in highly complex environments, often with multiple layers of access privileges, users, and interconnected systems. The need for effective identity governance in OT is arguably more critical than it is in IT given that OT systems are integrated with IT networks, and the risk of cyberattacks, unauthorized access, and compliance failures increases without proper oversight. Left unaddressed, these risks can lead to operational disruptions, safety issues, or regulatory penalties.

At Gathid, we specialize in simplifying identity governance for OT environments. Our platform enables industrial clients to quickly visualize, review, and manage complex access rights and roles across their entire infrastructure—from PLCs and SCADA systems to IT databases and cloud applications. With Gathid, you can review access by asset, identity, role, or privilege, all with just a few clicks. Daily updates and alerts ensure that changes and non-compliance issues are detected and addressed immediately.

By leveraging the Gathid Identity Graph, businesses gain full transparency into their ecosystem, allowing them to traverse complex systems, and unique access data structures, with ease. This proactivity is crucial for ensuring security and compliance in an ever-evolving OT landscape.
