NIST SP 800-53 Rev. 5 IR-2 — Incident Response Training

What this control requires

Provide role-based incident response training within a defined period, upon system changes, and periodically, while regularly updating training content to reflect current requirements and events. This control supports the Training Management System capability within the Incident Response family.

In plain English

Provide role-based incident response training within a defined period, upon system changes, and periodically, while regularly updating training content to reflect current requirements and events. In practice, this means you can prove you security management-level controls on a defined cadence.

Why it matters

SP 800-53 is the catalogue every U.S. federal authorisation (FedRAMP, FISMA, CMMC) and most regulated industries point at. A missing control surfaces as a Plan of Action & Milestones (POA&M) item that an Authorizing Official must approve before the Authority To Operate is granted or renewed.

What an auditor looks for

A 3PAO (FedRAMP) or Independent Assessor (NIST RMF) tests against NIST SP 800-53A assessment procedures. For each control they expect a documented implementation that addresses every assessment objective (Examine, Interview, Test) and an implementation summary in the System Security Plan.

Within Incident Response, the assessor will trace your implementation back to the catalogue reference (Control IR-2) and look for objective evidence on the latest two assessment cycles.

How to implement

Incident Response

Runbook. Maintain a runbook keyed by incident type with named roles (IC, comms, scribe), an out-of-band comms channel, and a 72-hour timeline for external notification.

Tabletop. Run a quarterly tabletop exercise (ransomware, insider, supply-chain) and feed gaps back into the runbook.

Operational checklist

• Security. Document the trigger, the owner and the cadence.
• Content. Document the trigger, the owner and the cadence.
• Response. Document the trigger, the owner and the cadence.
• Changes. Document the trigger, the owner and the cadence.
• System. Document the trigger, the owner and the cadence.
• Scope: management, system, system changes, events, capability, content, requirements, response.

Evidence to collect

• Ticketing Workflow. ticketing_workflow evidence

Workflow metrics (ServiceNow, Jira) show approvals and remediation. Focus: Incident Response Training.

Common pitfalls

• Runbooks that name a role but no person, or list a paging channel that no longer exists.
