This control supports the Breach Response capability within the Incident Response family. > > — NIST SP 800-53 Rev. 5, Control IR-8(1) ### In plain English Include processes in the incident response plan for handling PII breaches, assessing harm, determining notification needs, and ensuring compliance with privacy requirements. In practice, this means you can prove you policy 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. This control is rated **critical** in the source catalogue. Treat gaps here as production incidents in the risk register, not housekeeping. ## 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-8(1)) 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. #### Policy Management **Docs.** Keep each policy in version-controlled Markdown alongside the code that implements it; ship a signed PDF snapshot at each annual review and link the SHA into the SoA. ### Operational checklist - **Policy.** Document the trigger, the owner and the cadence. - **Notification.** Document the trigger, the owner and the cadence. - **Response.** Document the trigger, the owner and the cadence. - **Control.** Document the trigger, the owner and the cadence. - **Plan.** Document the trigger, the owner and the cadence. - **Scope:** management, privacy, notification, compliance, capability, response capability, response plan, policy. ## Evidence to collect - **Policy Document.** A signed and version-controlled policy / standard / procedure document. Signed policy or standard documents the safeguard. Focus: Breaches. ## Common pitfalls - Runbooks that name a role but no person, or list a paging channel that no longer exists. - Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced. ## How it maps to other frameworks Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit. - [**HIPAA (45 CFR Part 164) 164.406** — Notification to the Media](https://support.icompaas.com/compliance/hipaa/164-406-notification-to-the-media) - [**SOC 2 (2017 TSC) P6.5** — Third-Party Breach Notification Commitments](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/p6-5-third-party-breach-notification-commitments) - [**NIST SP 800-171 Rev. 3 3.1.9** — System Use Notification](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-1-9-system-use-notification) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control IR-1** — Policy And Procedures](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ir-1-policy-and-procedures) - [**Control IR-4(1)** — Automated Incident Handling Processes](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ir-4-1-automated-incident-handling-processes) - [**Control PM-27** — Privacy Reporting](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/pm-27-privacy-reporting) - [**Control RA-8** — Privacy Impact Assessments](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ra-8-privacy-impact-assessments) - [**Control IR-4(6)** — Insider Threats](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ir-4-6-insider-threats) - [**Control PL-2(3)** — Plan And Coordinate With Other Organizational Entities](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/pl-2-3-plan-and-coordinate-with-other-organizational-entities) ## References - [NIST Computer Security Resource Center — NIST SP 800-53 Rev. 5](https://csrc.nist.gov/Projects/risk-management/sp800-53-controls) - Catalogue identifier: `Control IR-8(1)` Topics: governance riskincident responseprivacy managementpolicy management ## Related compliance guidance - [NIST SP 800-53 Rev. 5: a practical implementation guide for cloud teams](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5): Start with the full NIST SP 800-53 implementation guide — scope, roadmap, evidence and how the assessment runs. - [NIST SP 800-171 and CMMC: a practical guide to protecting CUI in the cloud](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3): If your obligation is protecting CUI in your own systems for a federal or defence contract, this derived subset — not the full catalogue — is the requirement. - [SOC 2 compliance: a practical implementation guide for cloud-native SaaS teams](https://support.icompaas.com/compliance/soc-2-trust-services-criteria): Most commercial SaaS already hold a SOC 2 Type 2, and FedRAMP 20x Class A is designed for providers that have one.
