OT-Specific Incident Response and Recovery Plan

An IT incident-response plan does not fit the plant. OT response has to weigh safety and physical process first, involve engineers and operators alongside IT, and account for the reality that you may run degraded or in a safe state rather than simply pulling systems offline. A written, exercised OT plan — with roles, safe-state procedures, and tested recovery — is what prevents improvisation during a crisis.

OT-04 in 40 seconds

The problem, the plain-words meaning, three key moves, and what “done” looks like.

Official intent

What the campaign asks for

Have an OT-specific incident response and recovery plan so you respond to an OT incident without guessing. The official source remains authoritative.

Why it matters

In OT, a wrong response can be worse than the incident: isolating the wrong device can trip a process or create a safety hazard. Response decisions must be made with process owners, ahead of time, and rehearsed. Recovery also depends on validated backups of controller logic and configurations that most IT plans never cover.

Coordinate before touching production

Containment actions in OT — isolating a device, cutting a network path — can directly affect physical operations and safety systems. Every response and recovery procedure must be reviewed with process and safety owners, define safe-state options, and be exercised in a way that never puts production or people at risk.

Minimum / Strong / Advanced

1
Minimum

A written OT incident-response plan exists with named roles, contacts, and safe-state guidance distinct from the IT plan.

2
Strong

The plan covers detection, containment that accounts for safety, and recovery from validated OT backups; it is exercised at least annually.

3
Advanced

Playbooks cover likely OT scenarios, IT and OT respond jointly, and exercises and real events feed measured improvements.

Implementation timeline

First 24 hours
  • Confirm whether any OT-specific response plan exists
  • List who to call for an OT incident, including engineers and vendors
Next 30 days
  • Draft an OT IR plan with roles, contacts, and safe-state options
  • Confirm backups of controller logic/config exist
Next 60 days
  • Write playbooks for the most likely OT scenarios
  • Validate an OT recovery by test-restoring a configuration
By day 90
  • Run a tabletop exercise with IT, OT, and leadership
  • Fold lessons into the plan and set an annual cadence

Implementation steps

  1. Build an OT-specific IR plan with named roles spanning IT, OT engineering, operations, and leadership.
  2. Define containment options that weigh safety and process impact, including safe-state and degraded operation.
  3. Ensure recovery relies on validated backups of controller logic, configurations, and set points.
  4. Write playbooks for the incidents most likely to hit your environment.
  5. Exercise the plan at least annually with all stakeholders and update it from what you learn.

Validation

  • Confirm the OT plan names specific people and reachable after-hours contacts, not just titles.
  • Test-restore a controller configuration or logic backup to prove recovery works.
  • Verify the last tabletop involved OT engineers and produced changes to the plan.

Evidence to retain

Governance

OT incident-response and recovery plan with roles and safe-state procedures

Configuration

Inventory of controller logic/config backups used for recovery

Operations

Exercise reports and incident after-action records

Validation

Test-restore results and plan-revision history

Common failure modes

What looks done but is not

Reusing the IT plan unchanged, backups of servers but not of PLC logic and set points, and a plan that has never been exercised with the people who run the plant. A response plan first read during an incident is a liability.
