    NIST SP 800-53 / 800-171

    Federal control catalogs (800-53) and CUI-handling requirements (800-171) often referenced in MedTech contracts.

    Definition

    NIST Special Publication 800-53 "Security and Privacy Controls for Information Systems and Organizations" (Rev. 5, 2020) is the comprehensive federal control catalog used by US government systems. NIST SP 800-171 "Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations" (Rev. 3, 2024) is the subset of 800-53 controls applicable to private organizations that handle Controlled Unclassified Information (CUI). MedTech companies serving the VA, DoD, or BARDA-funded programs are routinely asked to map their security posture to these controls.
    What the regulation says
    FDA itself does not require 800-53/171 conformance, but federal customers do. CMMC (Cybersecurity Maturity Model Certification) for DoD contractors is built on 800-171. Many MedTech B2G sales cycles include a 800-171 self-assessment or third-party assessment.

    What this means in practice

    MedTech teams that touch federal customers typically maintain a 800-171 SSP (System Security Plan) and POA&M (Plan of Actions & Milestones). The control language overlaps heavily with ISO 27001 and NIST CSF, so a unified evidence base is achievable with planning.
    Common pitfalls
    • •Treating 800-171 as a one-time assessment rather than an ongoing posture.
    • •Failing to scope CUI accurately - over-scoping balloons cost, under-scoping fails audit.

    Frequently asked questions

    If the contract handles CUI, yes. Many VA medical-device contracts require 800-171 conformance and increasingly CMMC certification.
