Security requirement
Provide a centralized repository for the inventory of system components.
Discussion
Organizations may implement centralized system component inventories that include components from all organizational systems. Centralized repositories of component inventories provide opportunities for efficiencies in accounting for organizational hardware, software, and firmware assets. Such repositories can help organizations rapidly identify the location and responsible individuals of system components that have been compromised, breached, or are otherwise in need of mitigation actions. This requirement enhances SP 800-171 requirement 03.04.10.
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 Centralized Repository 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 approved baselines, secure configuration, change control, inventories, and drift management within the CUI boundary.
- 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.
- Resolve every organization-defined parameter through an approved governance and tailoring process.
- Map each clause of the requirement to an accountable owner, implementation mechanism, and evidence source.
- Verify that inherited and shared implementations are supported by current provider evidence and responsibility boundaries.
- 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
- approved baseline configurations
- change tickets and approvals
- configuration scan and drift reports
- software and hardware inventories
Common failure patterns
- baselines documented but not enforced
- emergency changes never reconciled
- cloud or ephemeral assets missing from inventory
- security impact analysis performed after deployment
Assessment objectives and methods
Assessment objectives (1)
a centralized repository for the inventory of system components is provided.
Examine
- Configuration management policy
- procedures addressing system component inventory
- configuration management plan
- system design documentation
- system security plan
- system component inventory
- system configuration settings and associated documentation
- change control records
- system security plan
- other relevant documents or records
Interview
- Organizational personnel with component inventory management responsibilities
- organizational personnel with security responsibilities
Test
- Organizational processes for managing the system component inventory
- mechanisms supporting and/or implementing system component inventory
