The Purdue Model for Network Security applies cybersecurity principles to industrial automation networks by segmenting them into different security zones. This structured approach helps organizations protect critical infrastructure from cyber threats while maintaining operational efficiency.
At the core of this model is the principle of network segmentation, which prevents unauthorized access to sensitive operational systems. Firewalls, demilitarized zones (DMZs), and intrusion prevention systems (IPS) are deployed to enforce strict access controls at each network level.
As cyberattacks targeting industrial environments increase, organizations are enhancing the Purdue Model with Zero Trust security, endpoint protection, and anomaly detection to ensure resilience against evolving cyber threats.
