What does COMSEC primarily focus on protecting?

COMSEC, short for Communications Security, primarily focuses on protecting the confidentiality, integrity, and availability of sensitive information during transmission. Its core objective is to ensure that communications are secure from unauthorized access or interception. This involves using various techniques and technologies, such as encryption and secure communication protocols, to safeguard the information being transmitted.

While other concepts like physical assets, data integrity, and information authenticity are important components of overall information security, they are not the main focus of COMSEC. Physical assets relate to securing the tangible elements required for communication, data integrity involves ensuring that the information has not been altered, and information authenticity ensures that the source of the information is verified. However, the essence of COMSEC is to create a secure environment specifically for communication processes to prevent unauthorized access and protect sensitive information during its transmission.
