Family: System and Services Acquisition Framework: NIST SP 800-171 Rev 3 Applicability: Systems processing, storing, or transmitting CUI
Require the providers of external system services used for the processing, storage, or transmission of CUI to comply with the following security requirements: [organization-defined]. Define and document user roles and responsibilities with regard to external system services, including shared responsibilities with external service providers. Implement processes, methods, and techniques to monitor security requirement compliance by external service providers on an ongoing basis.
Examine the SSP for External System Services (03.16.03) implementation description and responsible parties.
# Verify security controls protecting CUI
# Check access controls, encryption, monitoring as applicable
# For Linux systems:
ls -la /etc/security/ 2>/dev/null
grep -r "CUI\|controlled" /etc/security/ 2>/dev/null
# For cloud:
# Use cloud-audit-mcp tools to assess posture
Verify this requirement passes CMMC Level 2 assessment methodology per SP 800-171A Rev 3.

Require the providers of external system services used for the processing, storage, or transmission of CUI to comply with the following security requirements: [organization-defined]. Define and document user roles and responsibilities with regard to external system services, including shared responsibilities with external service providers. Implement processes, methods, and techniques to monitor security requirement compliance by external service providers on an ongoing basis.
External system services are provided by external service providers. Organizations establish relationships with external service providers in a variety of ways, including through business partnerships, contracts, interagency agreements, lines of business arrangements, licensing agreements, joint ventures, and supply chain exchanges. The responsibility for managing risks from the use of external system services remains with the organization charged with protecting CUI. Service-level agreements define expectations of performance, describe measurable outcomes, and identify remedies, mitigations, and response requirements for instances of noncompliance. Information from external service providers regarding the specific functions, ports, protocols, and services used in the provision of such services can be useful when there is a need to understand the trade-offs involved in restricting certain functions and services or blocking certain ports and protocols. This requirement is related to 03.01.20.
