Which term describes adding a layer of security over an existing app on the device?

• A. End of Support (EOS)
• B. Application Wrapping
• C. Bootloader Security
• D. Sideloading

Answer: (B)

Applying a security layer to an already-built app is done through application wrapping. This process places a protective envelope around the app so the device enforces additional policies—like authentication prompts, data encryption, or data leakage prevention—without needing to change the app’s original code. It’s a common enterprise tactic to secure apps on devices with varying ownership (BYOD or managed devices) while preserving the existing functionality. This differs from End of Support, which means a product isn’t receiving updates anymore; Bootloader Security focuses on protecting the device’s startup process; and Sideloading refers to installing apps from outside official stores, not adding a security layer to an existing app. Hence, wrapping best fits the idea of adding a security layer to an existing app.
