The Purdue Model for IT/OT Security is a cybersecurity framework that provides a structured approach to protecting industrial networks from cyber threats. It segments IT and OT networks into multiple layers, ensuring that sensitive operational systems are shielded from direct exposure to enterprise IT vulnerabilities.
By enforcing network segmentation and access controls, the Purdue Model helps organizations prevent unauthorized access, malware propagation, and industrial espionage. Security measures such as firewalls, intrusion detection systems (IDS), and multi-factor authentication (MFA) are commonly implemented at each level.
As industries increasingly adopt digital transformation, adapting the Purdue Model for IT/OT security is critical to safeguarding industrial control systems (ICS) against evolving cyber threats while maintaining seamless operational efficiency.
