The average DAR value is 3.50 points (7.00 points of system protection and 0.00 points of own protection). It equals to a typical value (3.5 points, where’s 7 points of system protection and 0 points of own protection).

Items 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.

Items with average value 5.00 points (6 points of system protection, 4 points of own protection) means data protection levels have following definitions.

It means your data can be stolen with a crafted preinstalled certificate on the device or if someone makes you install a certificate.
