This control supports the Governance capability within the Personnel Security family. > > — NIST SP 800-53 Rev. 5, Control PS-6(2) ### In plain English Verify that access to classified information requiring special protection is granted only to individuals who have a valid access authorization, satisfy personnel security criteria, and have signed a nondisclosure agreement. In practice, this means you can prove you access 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 **Personnel Security**, the assessor will trace your implementation back to the catalogue reference (Control PS-6(2)) and look for objective evidence on the latest two assessment cycles. ## How to implement 1. Write a short policy stating intent, scope and named owner. 2. Encode it as a platform guardrail — SCP, Azure Policy initiative, Organisation Policy, or repository policy. 3. Wire a monitoring signal that catches drift (CSPM rule, SIEM rule, scheduled query, Workspace alert) and ticket it. 4. Review on a documented cadence and capture the review in the risk register or compliance tracker. ### Operational checklist - **Access.** 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. - **Review.** Document the trigger, the owner and the cadence. - **Protection.** Document the trigger, the owner and the cadence. - **Scope:** management, authorization, information, only, personnel, protection, identity, review. ## Evidence to collect - **Identity Scan.** IAM / IdP exports — Entra ID, Okta, IAM Identity Center, Workspace directory — showing accounts, roles, MFA state and last sign-in. Identity analytics (Okta, SailPoint, Access Analyzer) demonstrates least-privilege. Focus: Classified Information Requiring Special Protection. ## 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. - [**NIST SP 800-171 Rev. 3 3.9.1** — Personnel Screening](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-9-1-personnel-screening) - [**ISO/IEC 27001:2022 A.5.2** — Information security roles and responsibilities](https://support.icompaas.com/compliance/iso-27001-2022/a-5-2-information-security-roles-and-responsibilities) - [**CIS Controls v8 9.2** — Use DNS Filtering Services](https://support.icompaas.com/compliance/cis-controls-v8/9-2-use-dns-filtering-services) - [**SOC 2 (2017 TSC) CC6.6** — Boundary Protection](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc6-6-boundary-protection) - [**ISO/IEC 27701:2025 A.3.8** — Identity management](https://support.icompaas.com/compliance/iso-27701-2025/a-3-8-identity-management) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control PS-6(3)** — Post-Employment Requirements](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ps-6-3-post-employment-requirements) - [**Control PS-3(3)** — Information Requiring Special Protection Measures](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ps-3-3-information-requiring-special-protection-measures) - [**Control PS-6(1)** — Information Requiring Special Protection](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ps-6-1-information-requiring-special-protection) - [**Control MP-6(7)** — Dual Authorization](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/mp-6-7-dual-authorization) - [**Control PE-5(1)** — Access To Output By Authorized Individuals](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/pe-5-1-access-to-output-by-authorized-individuals) - [**Control SC-42(1)** — Reporting To Authorized Individuals Or Roles](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sc-42-1-reporting-to-authorized-individuals-or-roles) ## 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 PS-6(2)` Topics: identity accessidentity managementaccess reviewprivileged access ## 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.
