Process sensors, analyzers, actuators and related instrumentation. Level 2 — Control systems — Supervising, monitoring and controlling the physical processes.
What is dematerialized zone in Purdue model of control hierarchy?
Level 3.5 – Demilitarized zone (DMZ): A recent addition over the last decade, this level includes security systems, such as firewalls and proxies, used to separate or air gap the IT and OT worlds. This is where the IT and OT worlds “converge,” increasing the attack surface for the OT systems.

What is data diode technology?
Data diodes are hardware-based devices with two nodes or circuits—one send only and one receive only—that allow the flow of data in one direction only, from a source to a destination. It is perhaps simplest to think of data diodes as one-way valves for data, allowing data to flow out, without a way back in.

What is a Purdue reference model?
Developed in the 1990s, the Purdue Reference Model, a part of Purdue Enterprise Reference Architecture (PERA), is a reference data flow model for Computer-Integrated Manufacturing (CIM), i. e., using computers to control the entire production process.
What are the advantages of the Purdue model?
One advantage of the Purdue model is its hierarchy. System components are clearly defined and components are grouped into distinct layers. Borders between the layers are logical places for network segmentation to control access between the layers. The model may not exactly fit your current OT network but is still a good starting point for securing an OT network.
What is the challenge of Purdue?
One challenge for the traditional Purdue Reference Model is IIoT devices. Modern ICS networks are becoming more digitally connected, and the border between IT and OT may not be as distinct as it used to be.
What are the components of IIoT?
Instead of the 6 layers in the Purdue model, IIoT environments may have a 3 component architecture, e.g., devices, field or cloud gateways, and a services backend . At the edge, IIoT devices may be wirelessly connected to the network and to a control hub or a field or cloud gateway. Field and cloud gateways are connected to backend services running on-premises or in the cloud for managing, monitoring, and analyzing IIoT data and providing an interface for remote user management access.
