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
