LLMResponse MA.L2-3.7.1.a

I'll help you prioritize your assessment approaches and evidence types for the MA.L2-3.7.1 requirement. Based on the CMMC Level 2 Assessment Guide and the specifics of this security practice, here's my recommendation:

Assessment Approaches Priority

1. **Examine** - This should be your first approach because system maintenance documentation provides foundational evidence of your maintenance program. Examining maintenance records, policies, and schedules will show that maintenance is performed systematically.

2. **Interview** - After reviewing documentation, interviewing personnel responsible for system maintenance can confirm that documented procedures are understood and actually followed.

3. **Test** - While valuable, testing should come after examining documentation and interviewing personnel. Testing can validate that maintenance processes are functioning as intended.

Evidence Types Ranking for Assessment Objective [a]

1. **Artifacts** - These provide the strongest evidence that system maintenance is actually performed. Examples include:

  - Maintenance logs and records
  - Patch management reports
  - Ticket/change management system records showing completed maintenance
  - System update logs

2. **Documents** - These provide the framework for your maintenance program:

  - System maintenance policy
  - Maintenance procedures
  - Vendor maintenance specifications
  - Maintenance schedules
  - System security plan sections addressing maintenance

3. **Screen Share** - This can demonstrate:

  - Live patch management system showing maintenance history
  - Configuration management systems showing updates
  - Ticket system showing maintenance workflow

4. **Physical Review** - While useful for hardware maintenance, this is less critical for the overall assessment:

  - Physical observation of hardware being maintained
  - Equipment maintenance logs maintained near the equipment
  - Review of maintenance areas and tools

For this particular assessment objective, the primary focus should be on collecting artifacts that prove maintenance is actually performed, supported by documents that show you have a structured program in place. Screen shares and physical reviews can supplement your primary evidence.
