OPSEC requires information to be shared on what basis?

• A. Need-To-Know basis.
• B. Public release to all personnel.
• C. Only with authorized contractors.
• D. Based on rank or unit.

Answer: (A)

Sharing in OPSEC is based on need to know: only people who have a legitimate, mission-essential reason to know specific information should have access to it. This keeps sensitive details from those who don’t need them, reducing the risk of disclosure to adversaries. Public release to everyone would defeat OPSEC, because it expands who could potentially expose critical data. Limiting access to authorized contractors isn’t the full story, since some internal personnel also need to know—based on their role—while others don’t. Similarly, access isn’t determined by rank or unit; what matters is whether the individual’s task requires the information.
