The important idea is that classification marking can be applied in multiple ways, as long as the information is clearly identifiable. For digital information, electronic labeling or metadata/headers often carries the classification. But when a medium can’t be marked electronically, other valid means of marking are allowed—such as physical labels, stamps, banners on documents, or labels on the container that holds the medium. Policies typically require that the classification is evident regardless of the medium, so both approaches can be correct depending on the situation. For example, a classified document on paper might have a clear header and a physical stamp, while a digital file might carry metadata or a visible digital banner. The key point is that the classification must be clearly identifiable, whether by electronic labeling or by appropriate physical marking when electronic labeling isn’t feasible.
