03.17 — Supply Chain Risk Management · NIST SP 800-172 Revision 3

Active
Official NIST requirement content

Security requirement

Establish agreements and procedures with entities involved in the supply chain for the system, system component, or system service for the [Organization-defined: SELECTED PARAMETER VALUE(S)].

Official NIST discussion

Discussion

Establishing agreements and procedures facilitates communications among supply chain entities. Early notification of compromises and potential compromises in the supply chain that may adversely affect or have adversely affected organizational systems or system components is essential for organizations to effectively respond to such incidents. The results of assessments or audits may include open-source information that contributed to a decision or result and could be used to help the supply chain entity resolve a concern or improve its processes. This requirement is sourced to a control tailored out of the SP 800-53B .13 moderate baseline in SP 800-171.

Official organization-defined parameters

Tailoring decisions required

Resolve these values through the governing organization’s approved tailoring and risk-management process before declaring the requirement implemented.

SELECTED PARAMETER VALUE(S)
informationorganization-defined informationinformation for which agreements and procedures are to be established is defined (if selected).
Official protection strategy classifications

Protection strategies supported

These classifications are carried from the official SP 800-172 OSCAL record and help explain the enhanced requirement’s defensive purpose.

Implementation perspective

Treat Notification Agreements as an enhanced CUI protection outcome for elevated threat conditions that must be reflected in the system boundary, documented implementation, operational behavior, and assessment evidence. Pay particular attention to supply-chain governance, provenance, supplier risk, component authenticity, and dependency resilience.

  1. Confirm the federal agency selected this enhanced requirement for the critical program or high-value asset and identify the CUI system components, services, users, and external connections in scope.
  2. Resolve every organization-defined parameter through an approved governance and tailoring process.
  3. Map each clause of the requirement to an accountable owner, implementation mechanism, and evidence source.
  4. Verify that inherited and shared implementations are supported by current provider evidence and responsibility boundaries.
  5. Collect evidence during normal operation and review changes, exceptions, and deficiencies on a risk-based cadence.

Questions to ask

  • Which critical-program or high-value-asset CUI, data flows, users, and services are protected by this enhanced requirement?
  • Which portions are implemented locally, inherited, shared, or not applicable, and what evidence supports that determination?
  • Do the system security plan, deployed configuration, operating process, and assessment evidence tell the same story?
  • What change, incident, or threshold should trigger reassessment?

Evidence and validation

  • supplier inventories and criticality ratings
  • contract security clauses
  • provenance and authenticity records
  • supplier monitoring and incident records

Common failure patterns

  • sub-tier dependencies ignored
  • contracts lacking evidence and notification obligations
  • open-source and service dependencies omitted
  • supplier risk reviewed only during procurement

Assessment objectives and methods

Assessment objectives (1)

  1. agreements and procedures are established with entities involved in the supply chain for the system, system components, or system service for [Organization-defined: SELECTED PARAMETER VALUE(S)].

Examine

  • Supply chain risk management policy and procedures
  • supply chain risk management plan
  • system and services acquisition policy
  • acquisition contracts for the system, system component, or system service
  • procedures addressing supply chain protection
  • acquisition documentation
  • service-level agreements
  • system security plan
  • inter-organizational agreements and procedures
  • other relevant documents or records

Interview

  • Personnel with system and service acquisition responsibilities
  • personnel with information security responsibilities
  • personnel with supply chain risk management responsibilities

Test

  • Processes for establishing inter-organizational agreements and procedures with supply chain entities
