Which organization is associated with the Purdue Model of network architecture?

The Purdue Model of network architecture is associated with the International Society of Automation (ISA). This model provides a structured approach for classifying and managing industrial control systems (ICS) and their interactions with enterprise IT environments. It establishes a framework that identifies various levels of system architecture—from the enterprise zone down to the control and device levels—allowing for improved security and risk management strategies for critical infrastructure.

The ISA plays a crucial role in developing standards and guidance that support the deployment of automation technologies. The use of the Purdue Model facilitates better communication among different sectors involved in industrial processes, promoting harmonized security practices and ensuring robust protection of essential services.

While the other organizations mentioned have significant contributions within the realm of cybersecurity and critical infrastructure protection, they are not directly linked to the Purdue Model as ISA is. For instance, CISSP focuses on certification for information security professionals, ICS-CERT offers support and resources for managing cybersecurity risks in ICS environments, and the DoD oversees various defense and military systems but does not specifically advocate for the Purdue Model.
