The Purdue Security Framework is an advanced cybersecurity model that extends the traditional Purdue Model by integrating modern security measures to protect industrial networks. This framework focuses on network segmentation, access control, and continuous monitoring to safeguard operational technology (OT) environments.
It includes key security elements such as multi-factor authentication (MFA), encryption, anomaly detection, and secure remote access. These controls ensure that only authorized users and devices can interact with critical industrial control systems (ICS) and supervisory control and data acquisition (SCADA) networks.
As industrial systems become more connected, the Purdue Security Framework helps organizations mitigate cyber risks, comply with industry standards (e.g., ISA/IEC 62443), and maintain operational continuity in the face of growing cybersecurity threats.
