Which of the following is NOT one of the aspects of information protection provided by COMSEC?

COMSEC, or Communications Security, focuses on ensuring the secure handling and transmission of information across communication channels. The primary aspects of COMSEC typically include confidentiality, integrity, and authenticity.

Confidentiality refers to the protection of information from unauthorized access, ensuring that sensitive data remains private. Integrity ensures that the information is not altered or tampered with during transmission or storage, confirming its accuracy and reliability. Authenticity verifies the identity of the information's source, confirming that the information received comes from a legitimate and trusted sender.

Compression, while it may relate to data transmission and improving efficiency, is not a focus of COMSEC. It does not contribute to the secure handling of information as defined by COMSEC principles. Thus, it stands out as not being one of the core aspects of information protection provided by COMSEC.
