(https://www.icompaas.com) **NIST SP 800-171 Rev. 3**·Requirement `3.9.2`·high·Component: **Personnel Security** ## What this control requires > This control requires disabling system access, terminating or revoking credentials, and retrieving security-related system property when an individual's employment is terminated. For personnel transfers or reassignments, the organization must review and modify access authorizations to align with the individual's new operational needs. This control supports the Access Termination capability within the Personnel Security (3.9) family. > > — NIST SP 800-171 Rev. 3, Requirement 3.9.2 ### In plain English This control requires disabling system access, terminating or revoking credentials, and retrieving security-related system property when an individual's employment is terminated. In practice, this means you can prove you access management-level controls on a defined cadence. ## Why it matters DoD contractors and their subcontractors must implement all 100 SP 800-171 requirements to keep CUI handling contracts. Gaps are scored against the SPRS scoring methodology; below a 110-point starting score, each unmet requirement deducts points and a below-threshold score can disqualify a bid. 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 C3PAO conducting a CMMC Level 2 assessment uses NIST SP 800-171A objectives. They expect a System Security Plan (SSP), Plan of Action & Milestones (POA&M) for any gaps, and objective evidence (configurations, ticket records, training records) for every requirement. Within **Personnel Security**, the assessor will trace your implementation back to the catalogue reference (Requirement 3.9.2) 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. - **System.** Document the trigger, the owner and the cadence. - **Personnel.** Document the trigger, the owner and the cadence. - **Security.** Document the trigger, the owner and the cadence. - **Scope:** management, termination, credentials, security, personnel, access authorizations. ## 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: Personnel Termination and Transfer. ## 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 800-53 Rev. 5 PS-4(2)** — Automated Actions](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ps-4-2-automated-actions) - [**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) - [**SOC 2 (2017 TSC) CC6.1** — Logical Access Controls](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc6-1-logical-access-controls) - [**CIS Controls v8 6.7** — Centralize Access Control](https://support.icompaas.com/compliance/cis-controls-v8/6-7-centralize-access-control) - [**BSI C5:2020 PS-04** — Physical site access control](https://support.icompaas.com/compliance/bsi-c5-2020/ps-04-physical-site-access-control) ## Related controls in NIST SP 800-171 Rev. 3 - [**Requirement 3.9.1** — Personnel Screening](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-9-1-personnel-screening) - [**Requirement 3.1.11** — Session Termination](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-1-11-session-termination) - [**Requirement 3.1.6** — Least Privilege - Privileged Accounts](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-1-6-least-privilege-privileged-accounts) - [**Requirement 3.10.1** — Physical Access Authorizations](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-10-1-physical-access-authorizations) - [**Requirement 3.1.4** — Separation of Duties](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-1-4-separation-of-duties) - [**Requirement 3.2.2** — Role-Based Training](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-2-2-role-based-training) ## References - [NIST Computer Security Resource Center — NIST SP 800-171 Rev. 3](https://csrc.nist.gov/pubs/sp/800/171/r3/final) - Catalogue identifier: `Requirement 3.9.2` Topics: identity accessidentity managementaccess reviewprivileged access ## Related compliance guidance - [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): Start with the full NIST SP 800-171 implementation guide — scope, roadmap, evidence and how the assessment runs. - [NIST SP 800-53 Rev. 5: a practical implementation guide for cloud teams](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5): The catalogue 800-171 is tailored from, and the basis of the FedRAMP Moderate baseline your cloud providers must meet for CUI. - [ISO/IEC 27001:2022 compliance: a practical implementation guide](https://support.icompaas.com/compliance/iso-27001-2022): If commercial customers ask for a certificate as well, most 800-171 controls can be evidenced once and mapped to Annex A.
