Understand the Purdue Reference Model for Industrial Control System network architecture — its five levels, how data flows between them, and how it guides OT network segmentation and security design.
The Purdue Reference Model for Computer Integrated Manufacturing was developed at Purdue University in the 1990s and later standardized as ISA-95. It defines a hierarchical model for organizing industrial control system networks into distinct levels, each with specific functions and communication relationships. The Purdue Model has become the foundational reference for ICS network architecture and OT cybersecurity segmentation.
