**NIST SP 800-53 Rev. 5**·Control `SC-7(10)`·high·Component: **System and Communications Protection**

## What this control requires

> Prevent intentional and unintentional information exfiltration using techniques like deep packet inspection, traffic profile analysis, and data loss prevention tools. Conduct exfiltration tests at organization-defined intervals. This control supports the Data Loss Prevention System capability within the System and Communications Protection family.

### In plain English

Prevent intentional and unintentional information exfiltration using techniques like deep packet inspection, traffic profile analysis, and data loss prevention tools. 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 **System and Communications Protection**, the assessor will trace your implementation back to the catalogue reference (Control SC-7(10)) 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.
-   **Data.** Document the trigger, the owner and the cadence.
-   **Protection.** Document the trigger, the owner and the cadence.
-   **System.** Document the trigger, the owner and the cadence.
-   **Scope:** management, information, organization, system, inspection, analysis, protection, capability.

## Evidence to collect

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

Signed policy or standard documents the safeguard. Focus: Prevent Exfiltration.

## Common pitfalls

-   Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced.
