The Purdue Model for Industrial Control Systems (ICS) is a widely used framework that organizes and secures automation and control networks. It segments ICS into different layers, defining interactions between physical devices, control systems, and enterprise applications.
This model is critical for structuring data flow and security between operational technology (OT) and information technology (IT). By defining security perimeters, the Purdue Model minimizes cybersecurity risks and protects critical infrastructure from unauthorized access.
In modern ICS environments, this model is evolving to accommodate Industrial IoT (IIoT) and cloud-based data integration. Organizations implementing the Purdue Model benefit from enhanced security, reduced downtime, and improved network resilience in industrial automation systems.
