Mapped to NIST 800-171 Requirement: 3.12.4
CMMC Assessment Objective: CA.L2-3.12.4[a]
What This Control Means
You must identify and define which assessments will be performed at the system level to verify:
• That security controls are implemented as intended
• That they operate correctly
• That they produce the desired outcome with respect to CUI protection
System-level assessments are often more technical and operational than broader risk assessments.
Why It Matters
If you don’t identify system-level assessments:
• You may miss control failures specific to technical systems
• Vulnerabilities may go unnoticed in production environments
• There may be no evidence of actual control performance
• You won’t meet core CMMC maturity and audit readiness expectations
This control ensures you validate how well controls work in real-world systems.
How to Implement It
1. Identify Systems That Handle CUI
• Include laptops, servers, cloud platforms, databases, and backup environments
• Focus on assets storing or transmitting CUI
2. Define Which Assessments Apply Examples include:
• Configuration audits
• Vulnerability scans
• Penetration testing
• Access control validation
• Logging and monitoring reviews
3. Set the Scope and Frequency
• Define how often each system-level assessment is conducted
• Use risk-based criteria to guide your decisions
4. Assign Responsibility
• Specify who conducts each type of assessment (internal staff, MSSP, third-party auditor)
5. Link to Security Plans
• Reference system-level assessments in your System Security Plan (SSP) or Security Assessment Plan (SAP)
Evidence the Assessor Will Look For
• List of system-level assessments scheduled or conducted
• Defined criteria for what constitutes a system-level evaluation
• Scans, test reports, or audit records tied to specific CUI systems
• Documentation linking assessments to security controls and system boundaries
• Role assignments for performing or overseeing the assessments
Common Gaps
• System-level assessments not defined separately from broader audits
• Technical systems left out of assessment plans
• Assessments occur but aren’t linked to CUI-relevant systems
• No regular schedule or defined responsibility for system-level tests
How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Helping define and schedule system-level assessments across your environment
• Mapping assessments to specific CUI systems and controls
• Tracking test frequency, results, and follow-up actions

• Storing documentation and outputs for audit readiness
With Cuick Trac, your assessments are scoped, targeted, and clearly aligned with CUI protection.
Final CTA
You can’t protect your systems unless you know how well your controls work inside them.
