Department of Energy information categorized as Restricted Data is classified under which policy?

The correct answer is National Disclosure Policy-1 (NDP-1) because Restricted Data pertains specifically to information related to atomic energy and nuclear weapons, and NDP-1 establishes the framework for the control and dissemination of such sensitive information. It outlines the conditions under which this data can be disclosed to foreign entities, ensuring that national security is prioritized while managing the risks associated with sharing classified information.

The other options do not specifically address the categorization and handling of Restricted Data. For example, National Standards Policy is broader and does not focus on classified information related to atomic energy. The Departmental Information Security Policy outlines the security processes within the department but does not directly govern the classification of Restricted Data. Similarly, Federal Classification Policy provides overarching principles for classifying information across all government sectors, but NDP-1 specifically targets the disclosure of Restricted Data.
