Which privacy principle should guide information sharing among units?

• A. Share all data with every unit to maximize awareness.
• B. Use secure channels, role-based access, encryption, and data minimization; only share necessary data.
• C. Keep data on personal devices for quick access.
• D. Archive data immediately without access controls.

Answer: (B)

When sharing information across units, the guiding principle is to protect privacy by sharing only what is needed and under appropriate controls. This approach uses secure channels to prevent interception, encryption to safeguard data at rest and in transit, and access controls like role-based access so only people with a legitimate need can view the data. Data minimization means only the essential information is shared, reducing exposure and complying with purpose limits and privacy laws. Together, these practices balance the need for interagency cooperation with the obligation to protect individuals’ privacy and maintain accountability. Sharing all data with every unit would expose more information than is necessary and increase privacy risks. Keeping data on personal devices creates uncontrolled access and potential leaks, undermining security and chain-of-custody. Archiving data immediately without access controls eliminates the ability to respond to ongoing needs and weakens governance and oversight.
