LLMResponse CM.L2-3.4.5.a
I'll help you assess each objective for CM.L2-3.4.5 (Access Restrictions for Change) and prioritize the assessment approaches and evidence types for each objective.
Assessment Objective [a]: Physical access restrictions associated with changes to the system are defined
Evidence Types Ranking:
1. **Documents**: Most valuable - look for formal documentation defining who can physically access systems for changes 2. **Artifacts**: Supporting - policies, procedures, access control matrices 3. **Screen Share**: Limited value - may show access control systems but not definitions 4. **Physical Review**: Limited for definitions (more useful for enforcement)
Assessment Approach Priority:
1. **Examine**: Most efficient starting point to review formal documentation
- Focus on configuration management policy, access restriction procedures, system security plan - Look for clearly defined lists of individuals authorized for physical access
2. **Interview**: Good secondary approach
- Talk with personnel responsible for physical access control - Discuss how physical access restrictions are defined and managed
3. **Test**: Least applicable for this objective
- Testing is more relevant for enforcement than definition
Each assessment objective requires a tailored approach with different emphasis on assessment methods and evidence types. The key is to ensure comprehensive coverage while focusing on the most relevant and efficient approaches for each specific objective.
