Which of the following is a primary goal of COMSEC measures?

The primary goal of COMSEC (Communications Security) measures is to deny unauthorized access to telecommunications information. This focus on safeguarding communications ensures that sensitive information remains confidential and secure from adversaries or unauthorized personnel. COMSEC encompasses various practices and technologies, including encryption, secure key management, and traffic security, all designed to protect communications channels and the data transmitted over them.

By prioritizing the denial of unauthorized access, COMSEC helps maintain the integrity of military operations and national security, as it prevents enemies from gaining valuable intelligence through intercepted communications. Protecting the confidentiality and authenticity of messages is crucial in military communications, where the compromise of information can have severe consequences. Thus, denying unauthorized access effectively fulfills the core objective of COMSEC initiatives.
