**NIST SP 800-53 Rev. 5**·Control `CM-3(1)`·high·Component: **Configuration Management**

## What this control requires

> Uses automated mechanisms to document, notify, and prohibit unapproved changes, ensuring all changes are tracked and authorized. This control supports the Automated Change Management capability within the Configuration Management family.

### In plain English

Uses automated mechanisms to document, notify, and prohibit unapproved changes, ensuring all changes are tracked and authorized. In practice, this means you can prove you policy 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-3(1)) and look for objective evidence on the latest two assessment cycles.

## How to implement

#### Incident Response

**Runbook.** Maintain a runbook keyed by incident type with named roles (IC, comms, scribe), an out-of-band comms channel, and a 72-hour timeline for external notification.

**Tabletop.** Run a quarterly tabletop exercise (ransomware, insider, supply-chain) and feed gaps back into the runbook.

#### Policy Management

**Docs.** Keep each policy in version-controlled Markdown alongside the code that implements it; ship a signed PDF snapshot at each annual review and link the SHA into the SoA.

### Operational checklist

-   **Policy.** Document the trigger, the owner and the cadence.
-   **Configuration.** Document the trigger, the owner and the cadence.
-   **Prohibit.** Document the trigger, the owner and the cadence.
-   **Notification.** Document the trigger, the owner and the cadence.
-   **Response.** Document the trigger, the owner and the cadence.
-   **Scope:** management, notification, configuration, capability, authorized, policy, uses, response.

## Evidence to collect

-   **Ticketing Workflow.** `ticketing_workflow` evidence
-   **Infra Scan.** Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings.

Workflow metrics (ServiceNow, Jira) show approvals and remediation. Focus: Automated Documentation, Notification, And Prohibition Of Changes.

## Common pitfalls

-   Runbooks that name a role but no person, or list a paging channel that no longer exists.
-   Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced.

## 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.
