This approach differs from static access control by allowing immediate revocation or adjustment of privileges without requiring users to restart their sessions. This control supports the Governance capability within the Access Control family. > > — NIST SP 800-53 Rev. 5, Control AC-2(6) ### In plain English Organizations must implement dynamic privilege management capabilities, where user privileges are adjusted in real-time based on operational needs and mission requirements. In practice, this means you can prove you dynamic 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 **Access Control**, the assessor will trace your implementation back to the catalogue reference (Control AC-2(6)) and look for objective evidence on the latest two assessment cycles. ## How to implement #### Code Review Testing **Pipeline.** Require at least one human reviewer plus passing CI (lint, type, unit, security scan) before merge — protected branches enforce this. ### Operational checklist - **Dynamic.** Document the trigger, the owner and the cadence. - **Access.** Document the trigger, the owner and the cadence. - **Revocation.** Document the trigger, the owner and the cadence. - **Review.** Document the trigger, the owner and the cadence. - **Privilege.** Document the trigger, the owner and the cadence. - **Scope:** management, privilege management, access control, mission, user privileges, time, 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: Dynamic Privilege Management. ## 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 3.1.6** — Least Privilege - Privileged Accounts](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-1-6-least-privilege-privileged-accounts) - [**CIS Controls v8 6.8** — Define and Maintain Role-Based Access Control](https://support.icompaas.com/compliance/cis-controls-v8/6-8-define-and-maintain-role-based-access-control) - [**ISO/IEC 27001:2022 A.5.18** — Access rights](https://support.icompaas.com/compliance/iso-27001-2022/a-5-18-access-rights) - [**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 800-53 Rev. 5 - [**Control AC-2(8)** — Dynamic Account Management](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-2-8-dynamic-account-management) - [**Control AC-6(7)** — Review Of User Privileges](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-6-7-review-of-user-privileges) - [**Control AC-17(9)** — Disconnect Or Disable Access](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-17-9-disconnect-or-disable-access) - [**Control AC-2(13)** — Disable Accounts For High-Risk Individuals](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-2-13-disable-accounts-for-high-risk-individuals) - [**Control AC-6(3)** — Network Access To Privileged Commands](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-6-3-network-access-to-privileged-commands) - [**Control AC-9** — Previous Logon Notification](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-9-previous-logon-notification) ## 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 AC-2(6)` Topics: governance riskidentity accessidentity managementaccess reviewcode review testingprivileged 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.
