Mobile App Sandbox

Operating system isolation that restricts each mobile app to its own data and resources unless granted permissions.

Definition

Android assigns each app a unique Linux user ID and enforces SELinux policies; iOS confines apps to a sandbox container with entitlements. The sandbox protects apps from each other, but rooting or jailbreaking breaks it.

Example

An app cannot read another app's private files because of the per-app sandbox.

Exam tip

Root/jailbreak removes sandbox guarantees, which is why apps may detect them.
