The requirement for permission before transmitting cryptosecurity or emissions security information is particularly associated with the role of the COMSEC Custodian. The COMSEC (Communications Security) Custodian is responsible for overseeing the handling and protection of cryptographic materials and ensuring compliance with relevant security policies and regulations. They serve as the authority on matters relating to the transmission of sensitive information, making it essential to obtain their permission before any such transmissions occur.

In contrast, while Security Officers, Designated Authorities, and Unit Commanders play vital roles in the overarching security framework, they may not have the specific authorization or expertise needed specifically to manage cryptosecurity protocols and the release of classified information like a COMSEC Custodian does. The COMSEC Custodian has specialized training and knowledge that make their oversight critical to maintaining the integrity and confidentiality of communications security.
