Limit component actions, support fine-grained privilege decomposition, and minimize access modes to only what's necessary. This control supports the Least Privilege Structuring Protocol capability within the System and Services Acquisition family. > > — NIST SP 800-53 Rev. 5, Control SA-17(7) ### In plain English Require developers to structure security-relevant hardware, software, and firmware to facilitate access control using least privilege. 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 **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 **System and Services Acquisition**, the assessor will trace your implementation back to the catalogue reference (Control SA-17(7)) 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. - **Security-Relevant.** Document the trigger, the owner and the cadence. - **Decomposition.** Document the trigger, the owner and the cadence. - **Least.** Document the trigger, the owner and the cadence. - **Review.** Document the trigger, the owner and the cadence. - **Scope:** management, actions, access control, system, only, privilege, identity, hardware. ## 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: Structure For Least Privilege. ## 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 6.7** — 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) - [**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) - [**India DPDP Act 2023 SE-002** — Role-Based Access Control (RBAC) & Least Privilege](https://support.icompaas.com/compliance/india-dpdp-act-2023/se-002-role-based-access-control-rbac-least-privilege) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control SA-8(14)** — Least Privilege](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-8-14-least-privilege) - [**Control AC-14** — Permitted Actions Without Identification Or Authentication](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-14-permitted-actions-without-identification-or-authentication) - [**Control AU-6(7)** — Permitted Actions](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/au-6-7-permitted-actions) - [**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 SC-3** — Security Function Isolation](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sc-3-security-function-isolation) - [**Control AC-6(10)** — Prohibit Non-Privileged Users From Executing Privileged Functions](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-6-10-prohibit-non-privileged-users-from-executing-privileged-functions) ## 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 SA-17(7)` 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.
