Which statement best describes the COMSEC User/Custodian role?

• A. The role is limited to IT personnel
• B. The role is limited to senior officers
• C. Anyone who uses COMSEC
• D. Only authorized couriers can be users

Answer: (C)

COMSEC revolves around protecting the confidentiality and proper use of crypto materials and devices. The User/Custodian role is defined by actually handling or using COMSEC in the course of duty, not by job title or rank. Anyone who uses COMSEC—whether to encrypt, decrypt, or operate the devices—must be authorized and properly trained, and the custodian part of the role is the person responsible for safeguarding and accounting for the crypto material in a given area. Since the role is about who interacts with COMSEC, it isn’t limited to IT staff, senior officers, or couriers; it encompasses anyone who uses COMSEC.
