  - Ensure documentation establishes what conditions warrant access

   - Talk with personnel responsible for physical access control
   - Talk with personnel responsible for physical access control
   - Discuss how physical access restrictions are defined and managed
  - Interview security administrators about access restriction definitions
 
   - Discuss with system administrators how physical access is determined
3. **Test**: Least applicable for this objective
  - Verify that definitions are understood by relevant personnel
   - Testing is more relevant for enforcement than definition
 
3. **Test** (Limited applicability for definitions)
   - Testing is more applicable for enforcement ([d]) than definition
  - Could verify that defined restrictions align with implemented controls
  - Generally less efficient for verifying definitions exist


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.
For this objective, your primary focus should be examining formal documentation, supported by interviews with key personnel to verify understanding of those definitions. Testing provides limited value for confirming definitions exist, but would be more valuable when assessing enforcement.

Assessment for Objective [a]: Physical access restrictions associated with changes to the system are defined

Evidence Types Ranking (Most to Least Valuable)

1. **Documents**: Most valuable 

  - Configuration management policy
  - Access restriction procedures 
  - System security plan
  - Configuration management plan
  - Documentation of authorized personnel lists

2. **Artifacts**: Strong supporting evidence 

  - Access control matrices
  - Role definitions
  - Change management workflows
  - Security requirements documentation

3. **Screen Share**: Limited value for definitions 

  - May show configuration of access control systems
  - But less useful for showing how restrictions are defined

4. **Physical Review**: Least applicable for definitions 

  - More valuable for enforcement verification
  - Limited ability to demonstrate definition aspects

Assessment Approach Priority

1. **Examine** (Primary approach) 

  - Review formal documentation that defines physical access restrictions
  - Check for clearly defined roles with physical access privileges
  - Look for documentation that specifies which roles can access sensitive areas
  - Verify documentation indicates what physical areas are restricted
  - Ensure documentation establishes what conditions warrant access

2. **Interview** (Complementary approach) 

  - Talk with personnel responsible for physical access control
  - Interview security administrators about access restriction definitions
  - Discuss with system administrators how physical access is determined
  - Verify that definitions are understood by relevant personnel

3. **Test** (Limited applicability for definitions) 

  - Testing is more applicable for enforcement ([d]) than definition
  - Could verify that defined restrictions align with implemented controls
  - Generally less efficient for verifying definitions exist

For this objective, your primary focus should be examining formal documentation, supported by interviews with key personnel to verify understanding of those definitions. Testing provides limited value for confirming definitions exist, but would be more valuable when assessing enforcement.
