File protection defines how data access relates to device locking. Derive the required access window from the product flow.
Evaluation approach
Check that creation, updates and temporary copies preserve the intended class. Do not spread a background-access exception to unrelated files.
Application example
A medical report preview is as sensitive as the original. Include temporary renderer output in the inventory.
Limits and considerations
Protecting the original does not automatically protect copies written elsewhere.
Finding secondary copies
Include previews, exports and sharing in tests. A helper may use different defaults from the main file. Repeat checks while device lock state changes.
Checks and decisions
- Find temporary copies
- Test lock states
- Verify output classes
