What is the key benefit of following the Purdue model for network diagrams?

The key benefit of following the Purdue model for network diagrams is its standardized layered approach. This model supports the organization of different levels of a network, which include enterprise, control, and physical processes. By categorizing these levels, it enables a clearer understanding of the complex interactions between various components of an industrial control system.

This standardized layering provides specific roles and responsibilities for each layer—such as information technology, operational technology, and enterprise systems. Such organization facilitates effective risk management, making it easier for stakeholders to identify vulnerabilities within each layer and implement appropriate security measures accordingly. The Purdue model also assists in communication among different teams by using a common framework, which aids in incident response and stakeholder engagement.

While other options might present certain benefits, the standardized layered approach of the Purdue model is particularly critical in managing the complexities inherent in modern networks, particularly in industrial settings where multiple systems interact.
