Section 4: Practical applications
The Purdue Model is not just a theoretical framework — it provides a practical foundation for designing secure and efficient industrial network architectures.
- Use firewalls between Level 3 and Level 4 to isolate OT from IT.
- Create DMZ zones between IT and OT for secure data exchange.
- Apply strict access control at each level based on role and function.
To help you understand the architecture, from the cybersecurity point of view, of an industrial environment according to the Purdue model, we have created a simulation of an industrial plant, indentifying the different components which create the IT and the OT networks.
By clicking in the different buttons, it is possible to access to the description of the different levels and elements, as well as their function, in the e global IT/OT networks.
