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.
