Operational technology (OT) visibility is the cornerstone of cybersecurity and resilience across public-sector critical infrastructure. The article highlights how water utilities, transportation systems, airports, seaports and large public facilities increasingly face cyber threats targeting industrial control systems and connected operational assets.
The key challenge is that many organizations lack a complete view of their OT environments. Drawing on OT assessments conducted by Kroll, the article recommends a practical, zero trust-aligned approach. This framework enables organizations to establish a risk baseline, discover assets, prioritize critical systems, implement security controls and operationalize monitoring.
