How are audio presentations marked to indicate classified information?

Audio presentations containing classified information must be marked at both the beginning and the end to clearly indicate the nature of the content throughout the entire duration of the presentation. This approach ensures that listeners are consistently aware of the classified status of the information being presented. By marking at both ends, individuals involved in handling or disseminating the audio are reminded of the necessary precautions to take regarding the classified material, thereby reinforcing security protocols and awareness.

Marking only at the end would create a situation where individuals might listen to classified content without realizing the potential sensitivity of the material during playback. Similarly, limiting markings solely to the cover sleeve would not provide adequate indication to those who may not see or engage with the physical cover while accessing the audio. The absence of required markings would compromise the identification and handling processes essential for maintaining the integrity and security of classified information. Thus, the requirement to mark at both the beginning and the end serves as a critical safeguard in information security practices.
