Audit Unknown-App Installation Access

Mission

Create a least-privilege plan for Android’s per-source APK installation setting.

Required work

1. Inventory browsers and file managers that could request install access
2. Select one trusted source for a fictional installation
3. Document the exact enable-install-disable sequence
4. Record platform warnings that must not be bypassed

Evidence to produce

A before/after checklist showing which source may install, why, and when access is removed.

Quality checks

The result must identify its source data, separate observation from assumption, preserve supplied originals, and explain any limitation or uncertain conclusion.
