This control supports the Coordination capability within the Contingency Planning family. > > — NIST SP 800-53 Rev. 5, Control CP-4(1) ### In plain English Coordinate contingency plan testing with related plans (e.g., Business Continuity, Incident Response) to ensure cohesive and effective organizational preparedness. In practice, this means you can prove you review 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 **high**. Auditors expect a named owner, a remediation SLA, and a tooling artefact that evidences continuous operation. ## 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 **Contingency Planning**, the assessor will trace your implementation back to the catalogue reference (Control CP-4(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. #### Business Continuity **BC/DR.** Define RTO/RPO per service, test backup restoration quarterly, and run a tabletop of full-region failover annually. **Backups.** Immutable backups (S3 Object Lock / Azure immutable storage / GCS bucket lock) plus an air-gapped copy for ransomware resilience. #### Code Review Testing **Pipeline.** Require at least one human reviewer plus passing CI (lint, type, unit, security scan) before merge — protected branches enforce this. ### Operational checklist - **Review.** 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. - **Testing,.** Document the trigger, the owner and the cadence. - **Scope:** management, e, review, contingency plan, capability, response, code. ## Evidence to collect - **Ticketing Workflow.** `ticketing_workflow` evidence Workflow metrics (ServiceNow, Jira) show approvals and remediation. Focus: Coordinate With Related Plans. ## Common pitfalls - Runbooks that name a role but no person, or list a paging channel that no longer exists. - DR plans that have never been tested in earnest, or that depend on an MFA token only one person can produce. ## 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. - [**SOC 2 (2017 TSC) CC7.4** — Incident Response](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc7-4-incident-response) - [**NIST SP 800-171 Rev. 3 3.6.5** — Incident Response Plan](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-6-5-incident-response-plan) - [**CIS Controls v8 17.7** — Conduct Routine Incident Response Exercises](https://support.icompaas.com/compliance/cis-controls-v8/17-7-conduct-routine-incident-response-exercises) - [**ISO/IEC 27001:2022 A.5.27** — Learning from information security incidents](https://support.icompaas.com/compliance/iso-27001-2022/a-5-27-learning-from-information-security-incidents) - [**BSI C5:2020 OPS-21** — Involvement of Cloud customers in the event of incidents](https://support.icompaas.com/compliance/bsi-c5-2020/ops-21-involvement-of-cloud-customers-in-the-event-of-incidents) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control CP-2(1)** — Coordinate With Related Plans](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cp-2-1-coordinate-with-related-plans) - [**Control CP-2** — Contingency Plan](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cp-2-contingency-plan) - [**Control IR-3** — Incident Response Testing](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ir-3-incident-response-testing) - [**Control IR-3(2)** — Coordination With Related Plans](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ir-3-2-coordination-with-related-plans) - [**Control SA-15(10)** — Incident Response Plan](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-15-10-incident-response-plan) - [**Control CP-4** — Contingency Plan Testing](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cp-4-contingency-plan-testing) ## 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 CP-4(1)` Topics: incident responsebusiness continuitychange managementcode review testing ## 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.
