Which of the following is the MOST appropriate control for asset data labeling procedures?

Logging data media to provide a physical inventory control is the most appropriate control because asset data labeling procedures are fundamentally about identifying, tracking, and cataloging physical and logical assets. Maintaining a physical inventory log directly supports labeling by ensuring each media item is recorded, accounted for, and can be associated with its classification label. This aligns with information security asset management standards (e.g., ISO/IEC 27001 A.8) which require organizations to maintain an inventory of assets as a foundational control for data labeling.

Reviewing audit trails of logging records is a detective control focused on monitoring and accountability after the fact, not a procedural control for labeling assets at the point of classification.

Categorizing the types of media being used addresses media classification at a general level but does not constitute a labeling procedure control for individual asset identification and inventory tracking.

Reviewing off-site storage access controls is a physical security control related to storage facility access management, which is unrelated to the labeling and identification of data assets.
