(https://www.icompaas.com) **NIST SP 800-53 Rev. 5**·Control `PS-7`·high·Component: **Personnel Security** ## What this control requires > Establish personnel security requirements, including security roles and responsibilities for external providers. Require external providers to comply with personnel security policies, document requirements, and notify organization-defined personnel of personnel transfers or terminations. Monitor compliance with security requirements for external providers. This control supports the Security Management capability within the Personnel Security family. > > — NIST SP 800-53 Rev. 5, Control PS-7 ### In plain English Establish personnel security requirements, including security roles and responsibilities for external providers. 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 **Personnel Security**, the assessor will trace your implementation back to the catalogue reference (Control PS-7) and look for objective evidence on the latest two assessment cycles. ## How to implement #### Logging Monitoring **AWS.** Org-trail CloudTrail to a central log archive account, GuardDuty in every region, and Security Hub for cross-source correlation. **Azure.** Pipe every diagnostic setting into a central Log Analytics workspace; onboard Microsoft Sentinel for SIEM/SOAR. **GCP.** Aggregate audit logs in a dedicated logging project with sink to BigQuery; enable Security Command Center Premium and route findings to Chronicle SIEM. #### 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. - **Security.** Document the trigger, the owner and the cadence. - **Monitor.** Document the trigger, the owner and the cadence. - **Control.** Document the trigger, the owner and the cadence. - **Compliance.** Document the trigger, the owner and the cadence. - **Scope:** management, organization, personnel, monitor, compliance, capability, external providers, policy. ## Evidence to collect - **Policy Document.** A signed and version-controlled policy / standard / procedure document. Signed policy or standard documents the safeguard. Focus: External Personnel Security. ## Common pitfalls - Per-account logging that nobody stitches together at the org level — incidents that cross accounts go undetected for days. - 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) 164.314(a)(2)(ii)** — Other Arrangements](https://support.icompaas.com/compliance/hipaa/164-314-a-2-ii-other-arrangements) - [**ISO/IEC 27001:2022 A.8.26** — Application security requirements](https://support.icompaas.com/compliance/iso-27001-2022/a-8-26-application-security-requirements) - [**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) - [**NIST SP 800-171 Rev. 3 3.3.5** — Audit Record Review, Analysis, and Reporting](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-3-5-audit-record-review-analysis-and-reporting) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control SA-21(1)** — Validation Of Screening](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-21-1-validation-of-screening) - [**Control PS-8** — Personnel Sanctions](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ps-8-personnel-sanctions) - [**Control PS-1** — Policy And Procedures](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ps-1-policy-and-procedures) - [**Control PS-4(1)** — Post-Employment Requirements](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ps-4-1-post-employment-requirements) - [**Control PS-3(4)** — Citizenship Requirements](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ps-3-4-citizenship-requirements) - [**Control SI-5** — Security Alerts, Advisories, And Directives](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/si-5-security-alerts-advisories-and-directives) ## 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-7` Topics: governance risklogging monitoringpolicy 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.
