### In plain English

Use automated tools to compare results from multiple vulnerability scans over time, helping identify emerging patterns, recurring weaknesses, and evolving attack vectors. In practice, this means you can prove you review 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.

## 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-5(6)) and look for objective evidence on the latest two assessment cycles.

## How to implement

#### 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.

#### Code Review Testing

**Pipeline.** Require at least one human reviewer plus passing CI (lint, type, unit, security scan) before merge — protected branches enforce this.

### Operational checklist

-   **Review.** Document the trigger, the owner and the cadence.
-   **Time.** Document the trigger, the owner and the cadence.
-   **Control.** Document the trigger, the owner and the cadence.
-   **Trend.** Document the trigger, the owner and the cadence.
-   **Testing,.** Document the trigger, the owner and the cadence.
-   **Scope:** management, time, analysis, assessment, analyses, review, capability, tools.

## Evidence to collect

-   **Vapt Scan.** `vapt_scan` evidence

Pen-test and vulnerability scan reports substantiate attack-surface coverage. Focus: Automated Trend Analyses.

## Common pitfalls

-   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.
