What document outlines the policies for safeguarding classified information?

The document that outlines the policies for safeguarding classified information is Executive Order 13526. This executive order was signed into law by the President and establishes the current framework for classifying, safeguarding, and declassifying national security information. It details the responsibilities of various agencies in protecting sensitive information and sets forth the procedures for handling classified materials. This order is essential in ensuring that information deemed critical to national security remains protected from unauthorized access, thus playing a vital role in information security across the Department of Defense and other federal agencies.

By contrast, the Federal Information Security Management Act focuses on protecting federal information systems and mandates agencies to develop, document, and implement an information security program but does not specifically address classified information. The National Defense Authorization Act primarily deals with defense budget and policy issues, and while it may reference certain security measures, it does not specifically establish policies for safeguarding classified information. Finally, the Privacy Act of 1974 is centered around the protection of individuals' privacy and personal data held by federal agencies, which is distinctly different from the classification and safeguarding of national security information.
