Operational Technology Security
Aug. 20, 2025
Team uComply
Operational Technology (OT) includes systems that control physical processes and is widely used in both private and industrial environments, including critical infrastructure. With increasing OT-related security incidents, implementation of protective measures is needed more than ever.
OT Security more important than ever
OT stands for Operational Technology and these are all systems and devices that control physical processes. We use (smart) equipment more and more, both in private and industrial environments. Think of the washing machine that you can run at the time you want or the robot vacuum cleaner that goes through the living room at fixed times. In business, OT is used for example; to run machines in factories, water treatment plants, traffic lights and bridge controls, loading and unloading in ports and warehouses.
Because OT is used in many places, and is deployed by organizations providing services or operating in critical infrastructure themselves, it is important to secure it. This is where the IEC 62443:2024 and the NIS2 provides guidance.
Risk profile - increase in OT-related incidents
OT Security - what can you do as an organization?
As an organization, you can start with the following steps:
- Inventory the OT systems you have;
- Identify information security and cybersecurity risks
- Take security measures
- Seek collaboration with suppliers and other parties that are part of the supply chain
Guidelines - NIS2 and IEC 62443
Among other things, the NIS2 provides guidance on securing the OT systems in an organization. Examples include:
- Conducting risk assessment (incl. supply chain);
- Assets mapping and classification;
- Reporting incidents
- Continuity measures
- Identify responsibilities regarding IT and OT.
- SCADA (supervisory control and data acquisition) systems.
