Which publication outlines the physical security and loss prevention for COMSEC?

• A. COMDTINST 5510.23
• B. OPNAVINST 5530.14
• C. SECNAV M5510.36
• D. EKMS 5 series

Answer: (B)

The publication that outlines physical security and loss prevention for Communication Security (COMSEC) is indeed OPNAVINST 5530.14. This instruction specifically addresses the requirements for safeguarding classified and sensitive information, emphasizing the need to establish and maintain robust physical security measures. Its focus includes guidelines on facility requirements, access controls, and the responsibilities of personnel in protecting COMSEC materials.

By providing a structured set of procedures and standards, it helps ensure that sensitive communications are not only encrypted securely but also safeguarded against unauthorized access or potential loss. This is critical for maintaining operational security and protecting national interests, as unauthorized disclosure can compromise mission success and the safety of personnel.

While other options may cover related topics, such as COMDTINST 5510.23, which deals with security programs in general, or SECNAV M5510.36, which addresses the broader security of Navy information, they do not focus specifically on the physical security aspects of COMSEC as comprehensively as OPNAVINST 5530.14 does. The EKMS 5 series provides guidance on specific operational procedures for Key Management Systems but does not outline physical security measures in the same focused manner.
