**NIST SP 800-53 Rev. 5**·Control `AU-13(1)`·high·Component: **Audit and Accountability**

## What this control requires

> Uses automated mechanisms, like scripts or commercial services, to monitor open-source sites for unauthorized disclosure of organizational information. This control supports the Automated Monitoring Tool capability within the Audit and Accountability family.

### In plain English

Uses automated mechanisms, like scripts or commercial services, to monitor open-source sites for unauthorized disclosure of organizational information. 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 **Audit and Accountability**, the assessor will trace your implementation back to the catalogue reference (Control AU-13(1)) and look for objective evidence on the latest two assessment cycles.

## How to implement

#### Logging Monitoring

**AWS.** Org-trail CloudTrail to a central log archive account, GuardDuty in every region, and Security Hub for cross-source correlation.

**Azure.** Pipe every diagnostic setting into a central Log Analytics workspace; onboard Microsoft Sentinel for SIEM/SOAR.

**GCP.** Aggregate audit logs in a dedicated logging project with sink to BigQuery; enable Security Command Center Premium and route findings to Chronicle SIEM.

#### 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.
-   **Audit.** Document the trigger, the owner and the cadence.
-   **Information.** Document the trigger, the owner and the cadence.
-   **Monitor.** Document the trigger, the owner and the cadence.
-   **Unauthorized.** Document the trigger, the owner and the cadence.
-   **Scope:** management, information, source, monitor, services, capability, accountability, tools.

## Evidence to collect

-   **Policy Document.** A signed and version-controlled policy / standard / procedure document.

Signed policy or standard documents the safeguard. Focus: Use Of Automated Tools.

## Common pitfalls

-   Per-account logging that nobody stitches together at the org level — incidents that cross accounts go undetected for days.
-   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.
