Industrial Control System Security: 5 Key Measures to Protect OT Infrastructure

In recent years, cyberattacks on OT (Operational Technology) infrastructure have become a reality not only for the energy sector but also for manufacturing, transportation, and water management. Attackers know that halting or disrupting production processes can have massive economic and social impacts.

5 key measures for OT infrastructure security:

1.     Network Segmentation – Separating IT and OT networks reduces the risk of malware spreading between environments.

2.     Updates and Patching – Regular software and firmware updates minimize vulnerabilities.

3.     Operational Monitoring – Using IDS/IPS systems to detect anomalies and unauthorized activities.

4.     Access Control – Implementing multi-factor authentication and strict user management.

5.     Incident Response Plan – A clearly defined incident response plan that includes testing and training.

Securing OT environments is no longer just about physical protection. A modern approach combines cyber and physical security measures to minimize risks and maintain operational continuity.
