The average DAR value is 4.36 points (7.00 points of system protection and 1.71 point of own protection). It is higher than a typical value (3.5 points, where’s 7 points of system protection and 0 points of own protection).

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.

– Screen Snapshots (‘Media Information’ Group) – Screenshots of your device screen running certain apps; common as an iOS app multitasking feature (app swipes) or browser tab swipes. This data item related to mentioned group meant to be any data like photo, image, video, audio,

– Device Details (‘Device Information’ Group) – Includes basic device details plus hardware key and fingerprints as well as IMEI. This data item related to mentioned group meant to be details about your device

Items’ GROUP #2 with average value 3.50 points (7 points of system protection, 0 points of own protection) means data protection levels have following definitions. Frankly talking, extra data found that shouldn’t be accessed where system protection level means – root/jailbreak is required but not possible without wiping device data, and own protection level means – stored as is.

– Document Details (‘Documents Information’ Group) – Common info about documents synchronized or stored locally (properties like size, date and time, etc.). This data item related to mentioned group meant to be any documents stored locally, uploaded, downloaded, synchronized in any file format,

– Application Configs (‘Application Information’ Group) – Different configuration files created by your app, perhaps app permissions. This data item related to mentioned group meant to be any info related to the app, app settings, including installed apps or installers

Also, keep in mind, using jailbroken device means the system protection level is 0 points and you’re using out-of-date iOS < 8.3 the system protection level is 2 points. If some data marked as shareable via iTunes, then the system protection level is 4 points.

The average DIT value is 5.40 points (5.00 points of system protection and 5.80 points of own protection). It is higher than a typical value (4 points, where’s 4 points of system protection and 4 points of own protection).

Items’ GROUP #1 with average value 5.50 points (5 points of system protection, 6 points of own protection) means data protection levels have following definitions. Frankly talking, data is not available all the time or partially accessed where system protection level means – some techniques are available to developers to keep connection bypassing system settings, like proxy settings, etc., and own protection level means – SSL pinning (can be patched).
