What is Purdue?
The Purdue Model is a framework for structuring and securing industrial control systems (ICS). It divides networks into zones based on functional tiers (e.g., sensors, control, monitoring).
Imagine a building with distinct security zones – only authorized personnel access specific areas.
Sicra and Purdue
Sicra uses the Purdue Model to identify vulnerabilities and where an incident are happening in the OT environment. We can also use the Purdue model to implement targeted improvements.
