How is "operational security" best maintained in the Navy?

Operational security (OPSEC) is crucial in maintaining the safety and effectiveness of military operations. It involves safeguarding sensitive information from being accessed by adversaries, ensuring that operational success is not compromised. Maintaining OPSEC in the Navy is best achieved by limiting access to sensitive information. This approach prevents unauthorized personnel from gaining insight into critical aspects of military operations, capabilities, and intentions, thereby reducing the risk of exploitation by potential threats.

By restricting information access, the Navy can ensure that only those individuals with the appropriate clearance and need-to-know are informed about specific missions or operational details. This practice helps maintain the element of surprise and protects operational integrity, which is essential for effective military strategy. The other options suggest practices that would expose sensitive information or undermine the very principles of OPSEC, highlighting the importance of limiting access as the most effective method.
