Assigning a data owner would best facilitate the implementation of data classification requirements. A data owner is responsible for defining the classification of the data, ensuring that the data is properly labeled, and approving access requests. Implementing technical control over the assets, implementing a data loss prevention (DLP) solution, and scheduling periodic audits are important activities, but they are not as effective as assigning a data owner.
