Ranking Evidence Types for Assessment Objective [a]

For the assessment objective "[a] the duties of individuals requiring separation are defined," I'll rank the evidence types supported by assessment objects from most to least valuable:

== Evidence Type Ranking ==

1. **Documents (highest value)**
- Access control policy documents
- Written procedures addressing divisions of responsibility and separation of duties
- System security plan with defined separation requirements
- List of divisions of responsibility and separation of duties
- Job descriptions that specify segregated duties

2. **Artifacts**
- System configuration settings showing role separations
- Role matrices showing incompatible functions
- Access control lists demonstrating separation implementation
- Organizational charts showing functional separation

3. **Physical Review**
- On-site verification of physical access controls supporting separation
- Observation of work areas arranged to support separation

4. **Screen Share (lowest value)**
- Demonstration of access control systems showing separation enforcement
- Viewing system configurations that implement separation

== Assessment Approach Prioritization ==

I recommend prioritizing the three assessment approaches as follows:

1. **Examine (highest priority)**
- Start by examining documentation that explicitly defines which duties require separation
- This provides the foundation for understanding how separation of duties is conceptualized in your organization
- Focus on formal policies, procedures, and system security plans

2. **Interview**
- After examining documents, interview personnel with responsibilities for defining divisions of responsibility
- Interview security personnel and system administrators to verify understanding
- These interviews validate that the documented definitions are understood and followed

3. **Test (supplementary)**
- Finally, test mechanisms implementing separation of duties
- This confirms that technical controls enforce the defined separations
- Testing serves as verification of actual implementation rather than primary evidence

This prioritization follows a logical progression: first understand what's defined, then verify understanding through interviews, and finally confirm implementation through testing.
