To address the assessment objective of ensuring that "paper media containing Controlled Unclassified Information (CUI) is physically controlled," it's important to understand which evidence types are most relevant and how they align with different assessment objects. Here's a structured approach:

Evidence Types Ranking

1. **Document**:

  - Documents such as system media protection policies, procedures for handling CUI, access control records, or inventory logs provide direct written evidence that outlines the processes in place.
  

2. **Physical Review**:

  - A physical review can verify that paper media is stored securely (e.g., locked drawers) and ensure that practices align with documented procedures.

3. **Artifacts**:

  - Artifacts like check-out forms or logs specifically related to paper media control serve as tangible records of adherence to policies.

4. **Screen Share**:

  - This might be less relevant for assessing physical controls over paper media, but it could support evidence if digital systems track access and handling digitally (e.g., viewing a digital log).

Prioritization of Assessment Approaches

1. **Examine**:

  - Examinations are crucial because they allow you to review documented policies, procedures, and records that demonstrate the organization's approach to controlling paper media containing CUI.

2. **Physical Review**:

  - Conducting a physical review is essential for verifying that security measures (like locked storage) are implemented in practice as per documentation.
  

3. **Interview**:

  - Interviews with personnel responsible for system media protection can provide insights and clarification on the implementation of policies, revealing gaps between policy and practice.

Implementation Steps

- Start by examining relevant documents to understand written procedures and controls. - Conduct a physical review to ensure these documented practices are being followed in reality. - Use interviews as needed to resolve any discrepancies found during examination or physical reviews and to gather insights into potential areas for improvement.

By following this structured approach, you can effectively assess the physical control of paper media containing CUI.
