Describe the COMSEC User/Custodian of the COMSEC program.

• A. Anyone who uses COMSEC
• B. IT staff only
• C. Only CRO can use
• D. Only commanders can use

Answer: (A)

COMSEC focuses on who has legitimate access to protect and use secure communications. The people who actually handle and operate with COMSEC material—encryptors, crypto keys, secure devices, and related procedures—are the users. The custodian is the person designated to safekeep, manage storage, distribution, and destruction of those materials, ensuring proper accountability. In practice, the important point is that access isn’t limited to a specific group like IT staff or leaders; anyone authorized to use COMSEC for their duties is part of the program. The custodian role exists to enforce safeguards and custody, but the active users come from all who need COMSEC to perform missions. So, the description that fits best is that anyone who uses COMSEC is part of the COMSEC program.
