This control supports the Anti-Counterfeit Scanning Tool capability within the System and Services Acquisition family. > > — NIST SP 800-53 Rev. 5, Control SA-19(4) ### In plain English Use scanning technologies to detect counterfeit components in the supply chain to ensure authenticity. 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 Services Acquisition**, the assessor will trace your implementation back to the catalogue reference (Control SA-19(4)) 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. #### 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. ### Operational checklist - **Policy.** Document the trigger, the owner and the cadence. - **Security.** Document the trigger, the owner and the cadence. - **Chain.** Document the trigger, the owner and the cadence. - **System.** Document the trigger, the owner and the cadence. - **Control.** Document the trigger, the owner and the cadence. - **Scope:** management, system, components, ensure authenticity, services, capability, policy, vulnerability. ## Evidence to collect - **Policy Document.** A signed and version-controlled policy / standard / procedure document. Signed policy or standard documents the safeguard. Focus: Anti-Counterfeit Scanning. ## Common pitfalls - Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced. - 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 3.17.3** — Supply Chain Requirements and Processes](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-17-3-supply-chain-requirements-and-processes) - [**ISO/IEC 27001:2022 A.5.21** — Managing information security in the ICT supply chain](https://support.icompaas.com/compliance/iso-27001-2022/a-5-21-managing-information-security-in-the-ict-supply-chain) - [**HIPAA (45 CFR Part 164) 164.308(a)(5)(i)** — Security Awareness and Training](https://support.icompaas.com/compliance/hipaa/164-308-a-5-i-security-awareness-and-training) - [**BSI C5:2020 SP-01** — Documentation, communication and provision of policies and instructions](https://support.icompaas.com/compliance/bsi-c5-2020/sp-01-documentation-communication-and-provision-of-policies-and-instructions) - [**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 SA-12(10)** — Validate As Genuine And Not Altered](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-12-10-validate-as-genuine-and-not-altered) - [**Control SA-19** — Component Authenticity](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-19-component-authenticity) - [**Control SA-12(11)** — Penetration Testing / Analysis Of Elements, Processes, And Actors](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-12-11-penetration-testing-analysis-of-elements-processes-and-actors) - [**Control SA-22(1)** — Alternative Sources For Continued Support](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-22-1-alternative-sources-for-continued-support) - [**Control SA-12(6)** — Minimizing Procurement Time](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-12-6-minimizing-procurement-time) - [**Control SA-12(12)** — Inter-Organizational Agreements](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-12-12-inter-organizational-agreements) ## 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 SA-19(4)` Topics: governance riskpolicy managementsupply chain securityvulnerability 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.
