This control supports the Vulnerability Scanning Tool capability within the Risk Assessment family. > > — NIST SP 800-53 Rev. 5, Control RA-5(1) ### In plain English Use vulnerability scanning tools that can readily update the list of vulnerabilities to be scanned as new threats are identified. 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. 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-5(1)) 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. - **Control.** Document the trigger, the owner and the cadence. - **Testing,.** Document the trigger, the owner and the cadence. - **Code.** Document the trigger, the owner and the cadence. - **Vulnerability.** Document the trigger, the owner and the cadence. - **Scope:** management, assessment, review, capability, threats, tools, vulnerability, tool capability. ## Evidence to collect - **Vapt Scan.** `vapt_scan` evidence - **Infra Scan.** Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings. Pen-test and vulnerability scan reports substantiate attack-surface coverage. Focus: Update Tool Capability. ## 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. - [**NIST SP 800-171 Rev. 3 3.11.2** — Vulnerability Monitoring and Scanning](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-11-2-vulnerability-monitoring-and-scanning) - [**CIS Controls v8 7.1** — Establish and Maintain a Vulnerability Management Process](https://support.icompaas.com/compliance/cis-controls-v8/7-1-establish-and-maintain-a-vulnerability-management-process) ## Related controls in NIST SP 800-53 Rev. 5 - [**Control RA-5(6)** — Automated Trend Analyses](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ra-5-6-automated-trend-analyses) - [**Control RA-5(9)** — Penetration Testing And Analyses](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ra-5-9-penetration-testing-and-analyses) - [**Control RA-5(10)** — Correlate Scanning Information](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ra-5-10-correlate-scanning-information) - [**Control RA-5(3)** — Breadth And Depth Of Coverage](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ra-5-3-breadth-and-depth-of-coverage) - [**Control CA-8(1)** — Independent Penetration Testing Agent Or Team](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ca-8-1-independent-penetration-testing-agent-or-team) - [**Control RA-5(2)** — Update Vulnerabilities To Be Scanned](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ra-5-2-update-vulnerabilities-to-be-scanned) ## References - [NIST Computer Security Resource Center — NIST SP 800-53 Rev. 5](https://csrc.nist.gov/Projects/risk-management/sp800-53-controls) - Catalogue identifier: `Control RA-5(1)` Topics: governance riskvulnerability managementcode review testingpatch management ## Related compliance guidance - [NIST SP 800-53 Rev. 5: a practical implementation guide for cloud teams](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5): Start with the full NIST SP 800-53 implementation guide — scope, roadmap, evidence and how the assessment runs. - [NIST SP 800-171 and CMMC: a practical guide to protecting CUI in the cloud](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3): If your obligation is protecting CUI in your own systems for a federal or defence contract, this derived subset — not the full catalogue — is the requirement. - [SOC 2 compliance: a practical implementation guide for cloud-native SaaS teams](https://support.icompaas.com/compliance/soc-2-trust-services-criteria): Most commercial SaaS already hold a SOC 2 Type 2, and FedRAMP 20x Class A is designed for providers that have one.
