This control supports the Restrictions capability within the Configuration Management family. > > — NIST SP 800-53 Rev. 5, Control CM-10(1) ### In plain English Establish restrictions on open-source software use to ensure secure source code access, vulnerability remediation, and licensing compliance using software asset management systems. In practice, this means you can prove you restrictions 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 **Configuration Management**, the assessor will trace your implementation back to the catalogue reference (Control CM-10(1)) and look for objective evidence on the latest two assessment cycles. ## How to implement #### Vulnerability Management **Scanners.** Pair an unauthenticated scanner (Nessus / Qualys / Tenable.io) for external surface with an authenticated agent for OS/library CVEs on every host. **SLA.** Document remediation SLAs by CVSS / EPSS: critical 7 days, high 30 days, medium 90 days; report monthly trend to leadership. **Containers.** Scan images in CI (Trivy / Grype / Snyk Container) AND at runtime; block deploys on critical findings without exception. ### Operational checklist - **Restrictions.** Document the trigger, the owner and the cadence. - **Access.** Document the trigger, the owner and the cadence. - **Configuration.** Document the trigger, the owner and the cadence. - **Review.** Document the trigger, the owner and the cadence. - **Identity.** Document the trigger, the owner and the cadence. - **Scope:** management, source, identity, configuration, software, compliance, 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. - **Infra Scan.** Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings. Identity analytics (Okta, SailPoint, Access Analyzer) demonstrates least-privilege. Focus: Open-Source Software. ## Common pitfalls - Scans that hit only the perimeter; missing authenticated scans of OS, runtime libs and base images so most CVEs are invisible. ## 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. - [**ISO/IEC 27001:2022 A.8.4** — Access to source code](https://support.icompaas.com/compliance/iso-27001-2022/a-8-4-access-to-source-code) - [**NIST SP 800-171 Rev. 3 3.4.5** — Access Restrictions for Change](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-4-5-access-restrictions-for-change) - [**CIS Controls v8 14.9** — Conduct Role-Specific Security Awareness and Skills Training](https://support.icompaas.com/compliance/cis-controls-v8/14-9-conduct-role-specific-security-awareness-and-skills-training) - [**BSI C5:2020 PSS-03** — Online Register of Known Vulnerabilities](https://support.icompaas.com/compliance/bsi-c5-2020/pss-03-online-register-of-known-vulnerabilities) - [**SOC 2 (2017 TSC) CC6.8** — Malicious Code Protection](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc6-8-malicious-code-protection) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control CP-9** — System Backup](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cp-9-system-backup) - [**Control CM-5(4)** — Dual Authorization](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cm-5-4-dual-authorization) - [**Control CM-5(1)** — Automated Access Enforcement And Audit Records](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cm-5-1-automated-access-enforcement-and-audit-records) - [**Control CM-8(5)** — No Duplicate Accounting Of Components](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cm-8-5-no-duplicate-accounting-of-components) - [**Control MA-5(3)** — Citizenship Requirements For Classified Systems](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ma-5-3-citizenship-requirements-for-classified-systems) - [**Control CM-7(2)** — Prevent Program Execution](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cm-7-2-prevent-program-execution) ## 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 CM-10(1)` Topics: identity accessidentity managementaccess reviewprivileged accessvulnerability 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.
