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 **Access Control**, the assessor will trace your implementation back to the catalogue reference (Control AC-17(10)) 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. - **Review.** Document the trigger, the owner and the cadence. - **Remote.** Document the trigger, the owner and the cadence. - **Authenticate.** Document the trigger, the owner and the cadence. - **Authentication.** Document the trigger, the owner and the cadence. - **Scope:** management, access control, authentication, only, remote commands, identity, review, capability. ## 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: Authenticate Remote Commands. ## 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. - [**CIS Controls v8 6.7** — Centralize Access Control](https://support.icompaas.com/compliance/cis-controls-v8/6-7-centralize-access-control) - [**NIST SP 800-171 Rev. 3 3.1.7** — Least Privilege - Privileged Functions](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-1-7-least-privilege-privileged-functions) - [**BSI C5:2020 PS-04** — Physical site access control](https://support.icompaas.com/compliance/bsi-c5-2020/ps-04-physical-site-access-control) - [**ISO/IEC 27001:2022 A.8.2** — Privileged access rights](https://support.icompaas.com/compliance/iso-27001-2022/a-8-2-privileged-access-rights) - [**SOC 2 (2017 TSC) CC6.1** — Logical Access Controls](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc6-1-logical-access-controls) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control AC-18(1)** — Authentication And Encryption](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-18-1-authentication-and-encryption) - [**Control MP-2(1)** — Automated Restricted Access](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/mp-2-1-automated-restricted-access) - [**Control AC-8** — System Use Notification](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-8-system-use-notification) - [**Control AC-11** — Device Lock](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-11-device-lock) - [**Control AC-21(2)** — Information Search And Retrieval](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-21-2-information-search-and-retrieval) - [**Control AC-24(1)** — Transmit Access Authorization Information](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-24-1-transmit-access-authorization-information) ## 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-17(10)` 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.
