To effectively assess that "digital media containing Controlled Unclassified Information (CUI) is physically controlled," it's important to identify and prioritize relevant evidence types based on different assessment objects. Here’s a structured approach:

Evidence Types Ranking

1. **Document**:

  - Documentation such as digital security policies, access control procedures, inventory logs of digital media devices, and data handling guidelines provide foundational evidence demonstrating the organization's commitment to controlling digital media.

2. **Physical Review**:

  - Conducting a physical review allows you to verify that measures like secure storage for devices (e.g., locked cabinets or rooms) are in place and align with documented policies.
  

3. **Artifacts**:

  - Artifacts such as audit logs, device check-out records, or access control lists serve as evidence of the practical implementation of controls.

4. **Screen Share**:

  - While not directly relevant to physical security, screen sharing can demonstrate how digital systems enforce and monitor policies (e.g., viewing a software interface that manages digital media usage).

Prioritization of Assessment Approaches

1. **Examine**:

  - Start by examining documents as they provide the baseline understanding of what controls should be in place for digitally securing CUI.

2. **Physical Review**:

  - Perform physical reviews to ensure that documented security measures are actively being implemented and maintained at storage locations or within operational environments.
  

3. **Interview**:

  - Interviews with personnel responsible for digital media management can provide context, help clarify any ambiguities found in documentation, and reveal insights into actual practices versus documented procedures.

Implementation Steps

- Begin by examining relevant documents to establish a theoretical understanding of policies and controls. - Conduct physical reviews to validate that these policies are effectively enforced in practice. - Use interviews as needed for additional context or clarification on the implementation status and effectiveness of digital media control measures.

By systematically following this approach, you can ensure thorough assessment and validation of physical controls over digital media containing CUI.
