Which is NOT a responsibility of the COMSEC Manager?

The role of a COMSEC Manager primarily revolves around the management and protection of communications security materials and systems, including the oversight of key inventory and the training of personnel on COMSEC practices and policies. While shipping equipment can be a logistical responsibility tied to the management of COMSEC materials, the key aspect is ensuring that the correct procedures are followed to maintain security.

Overseeing network security, however, typically falls under the domain of a cybersecurity or IT security role rather than specifically within the COMSEC Manager's responsibilities. The COMSEC Manager’s focus is on cryptographic key management and ensuring compliance with communications security standards, not necessarily the broad spectrum of network security. Therefore, this distinction clarifies that overseeing network security is outside the primary duties of a COMSEC Manager.
