Which statement best describes how COMSEC is maintained in maritime operations?

Which statement best describes how COMSEC is maintained in maritime operations?

• A. Use crypto devices, frequency hopping, and proper key management
• B. Public channels encryption
• C. Rely on physical security of communications
• D. Use only frequency hopping

Answer: (A)

Protecting maritime communications relies on three integrated measures: cryptographic devices that encrypt and authenticate the traffic, spread-spectrum techniques like frequency hopping to make interception and jamming harder, and rigorous key management to securely generate, distribute, store, update, and revoke cryptographic keys. All three are needed because encryption alone protects content, but without proper keys it can be broken; frequency hopping helps resist interception and disruption but does not by itself conceal the message; relying only on physical security leaves electronic signals vulnerable to capture and analysis. Together, crypto devices, frequency hopping, and disciplined key management form a complete COMSEC approach for maritime operations.
