LLMResponse CM.L2-3.4.3.a

I'll help you evaluate how to best collect evidence for the assessment objective "[a] changes to the system are tracked" within CM.L2-3.4.3. Based on the CMMC Level 2 Assessment Guide and your assessment approaches, I'll rank the evidence types and prioritize assessment approaches.

Evidence Types Ranking for "[a] changes to the system are tracked"

1. **Artifacts (I1)** - This is the highest priority evidence type because it provides direct proof that changes are being tracked. Examples include:

  - Change request forms/tickets
  - Change tracking logs
  - Configuration management database entries
  - Version control system logs
  - Change management tool exports showing tracked changes

2. **Documents (I2)** - The second most valuable evidence type would include:

  - Configuration management policy that mandates tracking changes
  - Procedures describing how changes are tracked
  - Process diagrams showing change tracking workflow
  - Change management plans
  - System security plan sections addressing change tracking

3. **Screen Share (I4)** - This is valuable for demonstrating the actual implementation:

  - Live demonstration of how change requests are entered and tracked
  - Showing the change tracking database/tool in operation
  - Displaying historical change records

4. **Physical Review (I3)** - This is ranked lower for this objective since change tracking is primarily digital, but could include:

  - Observing physical change control boards or meetings
  - Reviewing printed change logs or documentation

Assessment Approach Prioritization

1. **Examine (C1)** - This should be your primary approach because:

  - It allows direct review of the change tracking mechanisms
  - You can verify historical change records to confirm consistent tracking
  - It provides evidence of the complete change tracking lifecycle
  - Key assessment objects: change control records, system audit logs, configuration management plan

2. **Test (C3)** - This would be your second priority:

  - Verify that the change tracking process works by following a change through the system
  - Test that changes cannot bypass the tracking process
  - Validate that tracking mechanisms capture all required information
  - Key assessment objects: mechanisms that implement configuration change control

3. **Interview (C2)** - While still valuable, this would be your third priority:

  - Helps establish understanding of how change tracking is implemented
  - Confirms awareness and adherence to change tracking protocols
  - Reveals any informal or undocumented practices
  - Key personnel: system administrators, personnel with configuration change control responsibilities

Practical Implementation Strategy

For optimal assessment of "[a] changes to the system are tracked":

1. Start by examining your change management documentation, specifically looking for:

  - Defined process for tracking changes
  - Templates used for change requests
  - Change tracking logs or databases

2. Test the change tracking mechanisms by:

  - Observing a sample change going through your tracking process
  - Verifying that all changes have corresponding tracking records
  - Checking that change tracking tools record all necessary details

3. Interview key personnel to:

  - Confirm understanding of change tracking requirements
  - Validate that all types of changes (planned, emergency, etc.) are tracked
  - Identify any potential gaps in the tracking process

This approach will give you comprehensive evidence that your organization is meeting the requirement to track changes to organizational systems, which is essential for CMMC Level 2 compliance.
