Which document specifies the identification of persons authorized to accept controlled material?

The correct answer is AFI 16-1404, which specifically details the security measures and protocols needed regarding information security within the Air Force. This instruction includes guidelines on managing and authorizing personnel access to controlled material, ensuring that only those with the appropriate clearance and authorization are permitted to accept such materials.

This is crucial for maintaining the integrity and security of sensitive information and materials, as it defines the roles and responsibilities of personnel in protecting these assets. The instruction provides a framework that helps ensure compliance with broader security requirements, which is essential for effective management and control of sensitive resources.

In contrast, other documents such as AFMAN 23-122 primarily focus on logistics and general materiel management protocols, while AFI 31-401 deals with the overall information security program, and AFI 23-2308 outlines management approaches but does not specify authorization for accepting controlled material. Hence, AFI 16-1404 serves as the dedicated reference for guidelines about the identification of persons authorized to deal with controlled materials.
