Protection levels.

Locally stored data (Data-at-Rest, DAR).

Locally stored data groups include Documents Information, Credentials Information, Application Information, Address Book ‘n’ Contact Information.
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.

– 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,

– Document List (‘Documents Information’ Group) – The list of documents stored local or synchronized over the Internet. This data item related to mentioned group meant to be any documents stored locally, uploaded, downloaded, synchronized in any file format,

– Local ‘n’ Network Paths (‘Documents Information’ Group) – Paths about local or networks directories, folders, files. This data item related to mentioned group meant to be any documents stored locally, uploaded, downloaded, synchronized in any file format,

– Credentials (IDs) (‘Credentials Information’ Group) – Only account IDs like app or 3rd party user IDs including emails, phone number, usernames, etc. (depends on apps). This data item related to mentioned group meant to be any types of credentials including basic (IDs only), passwords, tokens, etc.,

– 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,

– Contact Short Profile (‘Address Book ‘n’ Contact Information’ Group) – Name, Email ID, Phone number of contacts. This data item related to mentioned group meant to be info locally stored, cached or transferred over the network and belong to this application if it’s social even

Keep in mind if you’re using some Android devices such Samsung, LG or another device with an unlocked or non-locked loader that allow rooting your device without user action, the system level equals 6 points instead of 7. It means your data can be stolen without involving your actions.

Transferred data (Data-in-Transit, DIT).

Transferred data groups include Credentials Information, Application Information, Account Information, Documents Information, Media Information, Device Information.
The average DIT value is 5.90 points (6.00 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 6.00 points (6 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 – MITM prevented or fake certificate importing prevented, but plaintext non-protected traffic is intercepted, and own protection level means – SSL pinning (can be patched).

– Credentials (IDs) (‘Credentials Information’ Group) – Only account IDs like app or 3rd party user IDs including emails, phone number, usernames, etc. (depends on apps). This data item related to mentioned group meant to be any types of credentials including basic (IDs only), passwords, tokens, etc.,

– Credentials (Passwords) (‘Credentials Information’ Group) – Well-known passwords or PINs you’re using to get access to your account (usually it is worse than tokens because it gives full access to your account). This data item related to mentioned group meant to be any types of credentials including basic (IDs only), passwords, tokens, etc.,

– 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,

– Account Settings ‘n’ Configs (‘Account Information’ Group) – Information about your account settings and configurations. This data item related to mentioned group meant to be any info related to profiles, basic credential IDs like email or username or phone number plus some more info depends on applications,

– Sync Documents (‘Documents Information’ Group) – Documents synchronized or locally stored on your device as is or converted into another file formats (like.pdf or set of separated jpg file per each .pdf file. This data item related to mentioned group meant to be any documents stored locally, uploaded, downloaded, synchronized in any file format,

– 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,

– Document List (‘Documents Information’ Group) – The list of documents stored local or synchronized over the Internet. This data item related to mentioned group meant to be any documents stored locally, uploaded, downloaded, synchronized in any file format,

This data item related to mentioned group meant to be any documents stored locally, uploaded, downloaded, synchronized in any file format

Items’ GROUP #2 with average value 5.00 points (6 points of system protection, 4 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 – MITM prevented or fake certificate importing prevented, but plaintext non-protected traffic is intercepted, and own protection level means – bypassed by fake/stolen root certificates.

– Device Data (‘Device Information’ Group) – Device ID, Device Name, Device OS Name and Version, and jailbroken/root status. This data item related to mentioned group meant to be details about your device

Keep in mind if you’re using out-of-date Android < 7.0, the system level equals 4 points instead of 6. It means your data can be stolen with a crafted preinstalled certificate on the device or if someone makes you install a certificate. Also, if you’re using out-of-date Android < 5.0, the system level equals 2 points instead of 4. It means your data can be stolen without involving your actions.
