Scope

What is assessed in OT security

IT/OT convergence, industrial control systems, and operational resilience.

IT/OT architecture

Segmentation, security zones, and conduits per IEC 62443.

Control systems

SCADA, PLC, RTU, HMI, and industrial protocols.

Operational resilience

Anomaly detection, OT incident response, and continuity.
