Why should I care?
Plant Asset Management Server sits at Level 3. Compromise here is not just a data problem — it changes what the physical process does or what operators can see and control.
Common security problems
- Very wide device reach from one host
- Shared maintenance accounts
If it is compromised
- Mass instrument configuration change
What to monitor
- Configuration writes
- Account use
- Bulk operations
How to defend it
- Named accounts with MFA
- Approval workflow for bulk operations
- Treat as an engineering asset
