The CISO’s 5 Step Guide to Securing Operational Technology (OT)
OT environments are the backbone of manufacturing and distribution, and they were built when isolation was the security model. As digital transformation opens them to new attack vectors, CISOs inherit responsibility for complex, interconnected systems never designed with security in mind. This guide lays out a practical five-step approach: understand your operational workflows and data needs, secure the network connecting your factories and devices, gain visibility and control over every asset, put backup and disaster recovery in place, and scale production on that foundation with Industrial DevOps and AI. Each step includes an action plan of specific decisions to make.
Key Takeaways
- Learn why documenting operational workflows and data needs comes before any architecture decision.
- Explore network segmentation, secure remote access, industrial protocol security, and legacy modernization as the foundation of a secure OT network.
- Understand how asset discovery, vulnerability management, and anomaly detection close the visibility gap — and why IT, OT, and security have to work as one team to do it.
- See how industrial code backup, version control, and rapid rollback support business continuity and regulatory requirements like NIS2.
- Discover how Industrial DevOps and AI let you scale production safely once the security foundation is in place.
