This notice should be accessible upon initial interaction and at regular intervals, ensuring that individuals understand how, why, and by whom their data is processed. It must identify the legal authority for processing, the purposes of processing, and include other relevant organizational details. > > — NIST SP 800-53 Rev. 5, Control PT-5 ### In plain English Provide individuals with a privacy notice that clearly explains the processing of personally identifiable information. 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 **Privacy Notice Communication Mechanism**, the assessor will trace your implementation back to the catalogue reference (Control PT-5) 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. - **Data.** Document the trigger, the owner and the cadence. - **Protection.** Document the trigger, the owner and the cadence. - **Identify.** Document the trigger, the owner and the cadence. - **Scope:** management, information, privacy, personally identifiable information, protection, details, policy, notice. ## Evidence to collect - **Policy Document.** A signed and version-controlled policy / standard / procedure document. Signed policy or standard documents the safeguard. Focus: Privacy Notice. ## 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. - [**India DPDP Act 2023 TR-001** — Standalone Privacy Notice](https://support.icompaas.com/compliance/india-dpdp-act-2023/tr-001-standalone-privacy-notice) - [**SOC 2 (2017 TSC) P2.1** — Communication of Data Subject Choices and Consequences](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/p2-1-communication-of-data-subject-choices-and-consequences) - [**HIPAA (45 CFR Part 164) 164.404(a)** — Notice to Individuals](https://support.icompaas.com/compliance/hipaa/164-404-a-notice-to-individuals) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control PT-5(1)** — Just-In-Time Notice](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/pt-5-1-just-in-time-notice) - [**Control SI-18(5)** — Notice Of Correction Or Deletion](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-18-5-notice-of-correction-or-deletion) - [**Control SI-19** — De-Identification](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-19-de-identification) - [**Control PT-6** — System Of Records Notice](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/pt-6-system-of-records-notice) - [**Control SI-18(4)** — Individual Requests](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-18-4-individual-requests) - [**Control SI-18(1)** — Automation Support](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-18-1-automation-support) ## 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 PT-5` Topics: governance riskdata protectionpolicy 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.
