Items’ GROUP #1 with average value 6.50 points (7 points of system protection, 6 points of own protection) means data protection levels have following definitions. Frankly talking, protection and privacy issues are still possible but might involve interaction with an app code where system protection level means – root/jailbreak is required but not possible without wiping device data, and own protection level means – data is not available in backups.
