This control supports the Assignment capability within the Configuration Management family. > > — NIST SP 800-53 Rev. 5, Control CM-8(9) ### In plain English Assign system components to a specific system with acknowledgment from designated personnel to ensure hardware, software, and firmware are managed, protected, and tracked, preventing vulnerabilities. In practice, this means you can prove you security 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-8(9)) and look for objective evidence on the latest two assessment cycles. ## How to implement #### Endpoint Protection **MDM.** Make MDM enrollment a hard gate for device access (Intune compliance + Conditional Access, or Jamf + Okta device trust). Unmanaged devices simply don't get a session token. **EDR.** Deploy CrowdStrike / SentinelOne / Defender for Endpoint to every server and laptop; alert on any host that stops sending telemetry for >24h. #### 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 - **Security.** Document the trigger, the owner and the cadence. - **Configuration.** Document the trigger, the owner and the cadence. - **Protection.** Document the trigger, the owner and the cadence. - **Hardware.** Document the trigger, the owner and the cadence. - **System.** Document the trigger, the owner and the cadence. - **Scope:** management, system, personnel, protection, configuration, hardware, software, firmware. ## Evidence to collect - **User Device Scan.** MDM compliance state per user device (Intune / Jamf / Workspace ONE). Endpoint compliance telemetry (Intune, Jamf) proves managed coverage. Focus: Assignment Of Components To Systems. ## Common pitfalls - Pilot MDM rollouts that quietly exclude executives or engineers; carving out the highest-risk users is the most common audit failure. - 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. - [**NIST SP 800-171 Rev. 3 3.4.11** — Information Location](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-4-11-information-location) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control CM-8(2)** — Automated Maintenance](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cm-8-2-automated-maintenance) - [**Control SA-17(2)** — Security-Relevant Components](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-17-2-security-relevant-components) - [**Control CM-8(1)** — Updates During Installation And Removal](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cm-8-1-updates-during-installation-and-removal) - [**Control SA-17(5)** — Conceptually Simple Design](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-17-5-conceptually-simple-design) - [**Control CM-7(9)** — Prohibiting The Use Of Unauthorized Hardware](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cm-7-9-prohibiting-the-use-of-unauthorized-hardware) - [**Control SA-17(6)** — Structure For Testing](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-17-6-structure-for-testing) ## 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-8(9)` Topics: endpoint securityendpoint protectionvulnerability 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.
