What is data minimization, and why is it important for Army data handling?

• A. Collect as much data as possible to ensure future use.
• B. Store data indefinitely regardless of need.
• C. Encrypt data after collection as the sole measure.
• D. Collect only data necessary for the stated purpose; reduces exposure risk and supports privacy.

Answer: (D)

Data minimization is about collecting only the data that is truly necessary to accomplish the stated purpose. This approach matters because every data item added to a system creates another potential target for misuse or breach and adds complexity to secure, store, and eventually dispose of it. By limiting collection, you reduce the exposure risk, make data handling simpler, and better protect privacy—an essential consideration when dealing with sensitive or personal information in Army data operations. In practice, you define the exact purpose, determine the minimum data needed to achieve that purpose, and avoid gathering or retaining anything beyond that. Encryption and strong controls are important, but they don’t substitute for collecting only what’s needed in the first place and managing that data’s lifecycle accordingly.
