Ranking Evidence Types and Assessment Approaches for CM.L2-3.4.2, Objective [b]

Based on the CMMC Level 2 Assessment Guide and the information you've provided about assessment objective [b], I'll rank the evidence types and prioritize the assessment approaches for effectively demonstrating compliance.

Evidence Types Ranking

For assessment objective [b] "security configuration settings for information technology products employed in the system are enforced":

1. **Artifacts** - Highest priority evidence type

  - System-generated reports showing active/enforced settings
  - Scan results demonstrating configuration compliance
  - Logs showing enforcement of configuration policies
  - Output from configuration validation tools
  - Automated enforcement mechanism logs
  - Exception reports showing detected violations

2. **Screen Share** - Second priority

  - Live demonstration of enforcement mechanisms
  - Real-time viewing of configuration management tools
  - Observation of how non-compliant configurations are detected
  - Demonstration of remediation processes
  - Showing how enforcement is monitored

3. **Physical Review** - Third priority

  - On-site inspection of systems to verify enforcement
  - Physical observation of controls that prevent unauthorized changes
  - Review of physical access restrictions for configuration management

4. **Documents** - Fourth priority

  - Enforcement policies and procedures
  - Remediation documentation for configuration violations
  - Reports showing compliance tracking over time
  - Documentation of enforcement tools and mechanisms

Assessment Approach Prioritization

1. **Test** - Highest priority approach

  - Test enforcement mechanisms directly
  - Verify that non-compliant settings are detected and prevented
  - Test how systems respond to attempts to change secure configurations
  - Confirm that monitoring tools accurately report on compliance
  - Validate that automated enforcement tools function as intended

2. **Examine** - Second priority

  - Review audit logs showing enforcement activities
  - Examine system-generated compliance reports
  - Check change control records for enforcement evidence
  - Examine documentation of enforcement mechanisms

3. **Interview** - Third priority

  - Interview personnel responsible for enforcement
  - Discuss procedures for handling configuration violations
  - Gather information about enforcement challenges and solutions
  - Understand how enforcement is maintained over time

This prioritization reflects the active nature of assessment objective [b], which focuses on enforcement rather than establishment of security configurations. For enforcement, direct testing and artifacts showing actual system behavior provide the strongest evidence that configurations are not just documented but actively enforced in practice.

When presenting your evidence to assessors, I recommend organizing it to clearly demonstrate: 1. How enforcement mechanisms work 2. What happens when non-compliant settings are detected 3. How consistent enforcement is maintained across all system components 4. Evidence that enforcement has been effective over time

This approach will provide assessors with confidence that your security configurations are not only established but actively enforced throughout your environment.
