What is the core function of a COMSEC Manager with regard to local custody?

The core function of a COMSEC Manager with regard to local custody is to maintain and manage the custody of COMSEC materials. This responsibility is critical to ensuring the security and integrity of sensitive information. The COMSEC Manager has to implement and enforce procedures for safeguarding classified documents, equipment, and communications materials to prevent unauthorized access or compromise. This role includes overseeing physical security measures, managing the issuance and return of materials, and ensuring that inventory records are accurately kept.

While approving access to secure materials, training personnel, and ensuring compliance with policies are important duties within a broader context, they are all subordinate to the essential function of managing custody. Without proper custody management, the risk of data breaches or compromise significantly increases, undermining the effectiveness of other policies and training efforts. Thus, maintaining and managing COMSEC materials is the foundational duty of the COMSEC Manager.
