Protection levels.

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

Locally stored data groups include Browser Information, Credentials Information, Account Information, Bookmark Information, Application Information, Log 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.

– History (‘Browser Information’ Group) – History items mainly described and defined by related group to certain item. This data item related to mentioned group meant to be any info browser stores (credentials, history, cached documents, media, etc.) and activities made via browser instead of native app,

– 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.,

– Media Data (‘Account Information’ Group) – Any info like images, audios, videos, media notes, etc. 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,

– Bookmark Data (‘Bookmark Information’ Group) – Some info about bookmarks like date and time and body. This data item related to mentioned group meant to be any information about bookmarks,

– Bookmark Details (‘Bookmark Information’ Group) – Details of bookmarks like date and time, time zone, place, participant’s info, body, linked data. This data item related to mentioned group meant to be any information about bookmarks,

– 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,

– Browser Content (‘Browser Information’ Group) – The content of pages opened in a browser with or without text, multimedia and so on, including credentials and passwords. This data item related to mentioned group meant to be any info browser stores (credentials, history, cached documents, media, etc.) and activities made via browser instead of native app,

– Screen Snapshots (‘Browser 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 info browser stores (credentials, history, cached documents, media, etc.) and activities made via browser instead of native app,

– Application Events (‘Log Information’ Group) – App events referred to user actions ‘n’ activities were done. This data item related to mentioned group meant to be any information stored in local or network logs,

– GEO Data (‘Log Information’ Group) – Any GEO info stored as plain text referred to the places or tracked activity. This data item related to mentioned group meant to be any information stored in local or network logs,

– Credentials (IDs) (‘Log 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 information stored in local or network logs,

– Media URLs (‘Log Information’ Group) – URLs related to media info such as stream media or profile’s media, etc. This data item related to mentioned group meant to be any information stored in local or network logs,

– Application Certificates ‘n’ Profile (‘Log Information’ Group) – Configuration files are known as certificates and profile for devices and apps including VPNs. This data item related to mentioned group meant to be any information stored in local or network logs

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 Device Information, Browser Information, Personal ‘n’ Private Information, Bookmark Information, Credentials Information.
The average DIT value is 5.83 points (6.00 points of system protection and 5.67 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 5.00 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,

Items’ GROUP #2 with average value 6.50 points (6 points of system protection, 7 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 – tricks to bypass sniffing (hardly to be or can’t be patched to bypass), including non-common or unsupported protocols.

– Tracked Data ‘n’ Favorites (‘Bookmark Information’ Group) – Any favorites data or tracked data marked as desirable by users and for users (Means, user is on FB messenger, Viber, bank client or favourite hotel, room type, flight route, airline). This data item related to mentioned group meant to be any information about bookmarks,

– Tracked Data ‘n’ Favorites (‘Personal ‘n’ Private Information’ Group) – Any favorites data or tracked data marked as desirable by users and for users (Means, user is on FB messenger, Viber, bank client or favourite hotel, room type, flight route, airline). This data item related to mentioned group meant to be any personal and private info is not grabbed from the 3rd party social networks or your IDs,

– History (‘Browser Information’ Group) – History items mainly described and defined by related group to certain item. This data item related to mentioned group meant to be any info browser stores (credentials, history, cached documents, media, etc.) and activities made via browser instead of native app

Items’ GROUP #3 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).

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.
