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 **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 **System and Services Acquisition**, the assessor will trace your implementation back to the catalogue reference (Control SA-2) and look for objective evidence on the latest two assessment cycles. ## How to implement #### 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. - **Information.** Document the trigger, the owner and the cadence. - **Security.** Document the trigger, the owner and the cadence. - **Protection.** Document the trigger, the owner and the cadence. - **System.** Document the trigger, the owner and the cadence. - **Scope:** management, information, privacy, system, protection, services, capability, allocation. ## Evidence to collect - **Policy Document.** A signed and version-controlled policy / standard / procedure document. Signed policy or standard documents the safeguard. Focus: Allocation Of Resources. ## Common pitfalls - 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. - [**ISO/IEC 27001:2022 A.5.23** — Information security for use of cloud services](https://support.icompaas.com/compliance/iso-27001-2022/a-5-23-information-security-for-use-of-cloud-services) - [**HIPAA (45 CFR Part 164) 164.314(a)(2)(ii)** — Other Arrangements](https://support.icompaas.com/compliance/hipaa/164-314-a-2-ii-other-arrangements) - [**NIST SP 800-171 Rev. 3 3.4.11** — Information Location](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-4-11-information-location) - [**BSI C5:2020 SP-01** — Documentation, communication and provision of policies and instructions](https://support.icompaas.com/compliance/bsi-c5-2020/sp-01-documentation-communication-and-provision-of-policies-and-instructions) - [**ISO/IEC 27701:2025 A.3.4** — Information security roles & responsibilities](https://support.icompaas.com/compliance/iso-27701-2025/a-3-4-information-security-roles-responsibilities) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control SA-4** — Acquisition Process](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-4-acquisition-process) - [**Control SA-5(3)** — High-Level Design](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-5-3-high-level-design) - [**Control SA-12(1)** — Acquisition Strategies, Tools, And Methods](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-12-1-acquisition-strategies-tools-and-methods) - [**Control SA-17(1)** — Formal Policy Model](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-17-1-formal-policy-model) - [**Control SA-15** — Development Process, Standards, And Tools](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-15-development-process-standards-and-tools) - [**Control SA-5(1)** — Functional Properties Of Security Controls](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-5-1-functional-properties-of-security-controls) ## 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 SA-2` Topics: governance riskpolicy managementprivacy 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.
