Critical OT Assets

This table is your “crown jewels” queue. It bridges OT realities (maintenance windows, safety) with security actions (quarantine, traffic filtering, access deny).

• Risk score per asset based on vulnerability + behavior anomalies + zone criticality.
• Last enforcement action logs what control was applied (policy enforced, quarantined, session terminated).
• Status indicates current protection state and required attention.

   : prefer traffic filtering and session restrictions before hard blocks.
3. 3

   assets immediately and verify physical/process safety impacts.
4. 4
   Export the list

   for plant managers and auditors as proof of active risk management.
