To promote information sharing, which guideline is referenced in relation to classification and marking of information?

The guideline most closely referenced in relation to the classification and marking of information to promote information sharing is found in DoD Manual 5200.01, Volumes 1 and 2. This manual provides detailed instructions on the classification of information and the procedures for its dissemination, including the criteria required to ensure that information is marked appropriately.

The contents of these volumes specifically address how to handle classified information in a way that supports both security and the sharing of relevant data, facilitating effective communication among authorized personnel while safeguarding national security. This aligns with the consistent push within the Department of Defense to balance the need for security with the imperative of sharing information in appropriate contexts.

In contrast, the other options refer to broader policies or directives that may not solely focus on the specific operational aspects of classification and marking that are outlined in the manuals. Therefore, those documents may provide general guidance or high-level policy directions but do not detail the operational procedures concerning classification and information sharing as comprehensively as DoD Manual 5200.01, Volumes 1 and 2 do.
