What document outlines communication security handling procedures?

The document that outlines communication security handling procedures is AFI 31-501. This Air Force Instruction provides detailed guidance and standards regarding the protection and handling of communication security (COMSEC) materials, which are crucial for safeguarding sensitive information and ensuring secure communications within the military.

AFI 31-501 establishes the framework necessary for personnel to understand their responsibilities in protecting communications, detailing the processes for the use, storage, destruction, and accountability of COMSEC materials. This involves ensuring proper training for personnel who handle such materials and implementing protocols that align with national security policies.

Other choices, while related to security and information management in various capacities, specifically target different areas of Air Force operations and security protocols. For instance, AFI 31-301 primarily deals with physical security measures, AFI 31-401 focuses on information security programs, and AFI 31-601 pertains to the overall policies regarding personnel security, none of which directly address the handling of communication security procedures like AFI 31-501 does.
