OT Network Segmentation — DMZ Design for Industrial Systems

IT/OT integration 14 min read NERC CIP · IEC 62443 PROMEC Systems

Connecting an OT network to enterprise infrastructure without proper segmentation is one of the highest-risk things an industrial organisation can do. Not because connectivity is inherently dangerous — but because most teams design the firewall rules before they design the architecture, put the wrong servers in the wrong zones, and create paths between IT and OT that are never documented and therefore never reviewed.
