**NIST SP 800-53 Rev. 5**·Control `RA-3(2)`·high·Component: **Risk Assessment**

## What this control requires

> Leverage information from all intelligence sources--open, technical, human, and environmental--to assess risks from suppliers, processes, people, and systems throughout development and delivery phases. This control supports the Intelligence Integration Module capability within the Risk Assessment family.

### In plain English

Leverage information from all intelligence sources--open, technical, human, and environmental--to assess risks from suppliers, processes, people, and systems throughout development and delivery phases. 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 **Risk Assessment**, the assessor will trace your implementation back to the catalogue reference (Control RA-3(2)) and look for objective evidence on the latest two assessment cycles.

## How to implement

#### 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.
-   **Information.** Document the trigger, the owner and the cadence.
-   **Security.** Document the trigger, the owner and the cadence.
-   **Human.** Document the trigger, the owner and the cadence.
-   **Environmental.** Document the trigger, the owner and the cadence.
-   **Scope:** management, information, controls, source, assessment, sources, capability, systems.

## Evidence to collect

-   **Vendor Risk Management.** `vendor_risk_management` evidence
-   **Policy Document.** A signed and version-controlled policy / standard / procedure document.

Third-party risk management evidence (assessments, contracts, due diligence) shows supplier oversight. Signed policy or standard documents the safeguard. Focus: Use Of All-Source Intelligence.

## Common pitfalls

-   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.
