Android is a secure operating system that has strong [app sandboxing](https://source.android.com/security/app-sandbox), [Verified Boot](https://source.android.com/security/verifiedboot) (AVB), and a robust [permission](https://developer.android.com/guide/topics/permissions/overview) control system.
Android является безопасной операционной системой, имеющей мощную [изоляцию приложений](https://source.android.com/security/app-sandbox), [проверенную загрузка](https://source.android.com/security/verifiedboot) (AVB) и надежную систему управления [разрешениями](https://developer.android.com/guide/topics/permissions/overview).
## Choosing an Android Distribution
## Выбор Android дистрибутива
When you buy an Android phone, the device's default operating system often comes with invasive integration with apps and services that are not part of the [Android Open-Source Project](https://source.android.com/). An example of such is Google Play Services, which has irrevocable privileges to access your files, contacts storage, call logs, SMS messages, location, camera, microphone, hardware identifiers, and so on. These apps and services increase the attack surface of your device and are the source of various privacy concerns with Android.
При покупке Android телефона, стандартная операционная система часто содержит приложения и интеграции с сервисами, которые не являются частью [проекта с открытым исходным кодом Android](https://source.android.com/). Примером могут служить Google Play Services, которые имеют неотменяемые привилегии на доступ к вашим файлам, хранилищу контактов, журналам вызовов, SMS-сообщениям, местоположению, камере, микрофону, аппаратным идентификаторам и так далее. Эти приложения и службы увеличивают поверхность атаки вашего устройства и являются источником различных проблем с конфиденциальностью в Android.
This problem could be solved by using a custom Android distribution that does not come with such invasive integration. Unfortunately, many custom Android distributions often violate the Android security model by not supporting critical security features such as AVB, rollback protection, firmware updates, and so on. Some distributions also ship [`userdebug`](https://source.android.com/setup/build/building#choose-a-target) builds which expose root via [ADB](https://developer.android.com/studio/command-line/adb) and require [more permissive](https://github.com/LineageOS/android_system_sepolicy/search?q=userdebug&type=code) SELinux policies to accommodate debugging features, resulting in a further increased attack surface and weakened security model.
Эта проблема может быть решена с помощью кастомного дистрибутива Android, который не имеет таких интеграций. К сожалению, многие кастомные дистрибутивы Android часто нарушают модель безопасности Android, не поддерживая критические функции безопасности, такие как AVB, защита rollback, обновления прошивки и так далее. Некоторые дистрибутивы поставляют сборки [`userdebug`](https://source.android.com/setup/build/building#choose-a-target), которые используют root с [ADB](https://developer.android.com/studio/command-line/adb) и требуют [более слабых](https://github.com/LineageOS/android_system_sepolicy/search?q=userdebug&type=code) политик SELinux для активации функций отладки, что приводит к увеличенной поверхности атаки и ослабленной модели безопасности.
Ideally, when choosing a custom Android distribution, you should make sure that it upholds the Android security model. At the very least, the distribution should have production builds, support for AVB, rollback protection, timely firmware and operating system updates, and SELinux in [enforcing mode](https://source.android.com/security/selinux/concepts#enforcement_levels). All of our recommended Android distributions satisfy these criteria.
В идеале, при выборе кастомного дистрибутива Android, вы должны убедиться, что он поддерживает модель безопасности Android. Как минимум, дистрибутив должен иметь production сборки, поддержку AVB, защиту rollback, своевременные обновления прошивки и операционной системы и SELinux в режиме [enforcing](https://source.android.com/security/selinux/concepts#enforcement_levels). Все рекомендованные нами дистрибутивы Android удовлетворяют этим критериям.

## Avoid Rooting
## Избегайте рутинга
[Rooting](https://en.wikipedia.org/wiki/Rooting_(Android)) Android phones can decrease security significantly as it weakens the complete [Android security model](https://en.wikipedia.org/wiki/Android_(operating_system)#Security_and_privacy). This can decrease privacy should there be an exploit that is assisted by the decreased security. Common rooting methods involve directly tampering with the boot partition, making it impossible to perform successful Verified Boot. Apps that require root will also modify the system partition meaning that Verified Boot would have to remain disabled. Having root exposed directly in the user interface also increases the [attack surface](https://en.wikipedia.org/wiki/Attack_surface) of your device and may assist in [privilege escalation](https://en.wikipedia.org/wiki/Privilege_escalation) vulnerabilities and SELinux policy bypasses.

Many OEMs also have broken implementation of Verified Boot that you have to be aware of beyond their marketing. For example, the Fairphone 3 and 4 are not secure by default, as the [stock bootloader trusts the public AVB signing key](https://forum.fairphone.com/t/bootloader-avb-keys-used-in-roms-for-fairphone-3-4/83448/11).

## Обновления прошивки
Firmware updates are critical for maintaining security and without them your device cannot be secure.

## Android Versions
## Версии Android
It's important to not use an [end-of-life](https://endoflife.date/android) version of Android. Newer versions of Android not only receive security updates for the operating system but also important privacy enhancing updates too. For example, [prior to Android 10](https://developer.android.com/about/versions/10/privacy/changes), any apps with the [`READ_PHONE_STATE`](https://developer.android.com/reference/android/Manifest.permission#READ_PHONE_STATE) permission could access sensitive and unique serial numbers of your phone such as [IMEI](https://en.wikipedia.org/wiki/International_Mobile_Equipment_Identity), [MEID](https://en.wikipedia.org/wiki/Mobile_equipment_identifier), your SIM card's [IMSI](https://en.wikipedia.org/wiki/International_mobile_subscriber_identity), whereas now they must be system apps to do so. System apps are only provided by the OEM or Android distribution.
## Android Permissions
## Разрешения в Android
[Permissions on Android](https://developer.android.com/guide/topics/permissions/overview) grant you control over what apps are allowed to access. Google regularly makes [improvements](https://developer.android.com/about/versions/11/privacy/permissions) on the permission system in each successive version. All apps you install are strictly [sandboxed](https://source.android.com/security/app-sandbox), therefore, there is no need to install any antivirus apps.

A smartphone with the latest version of Android will always be more secure than an old smartphone with an antivirus that you have paid for. It's better not to pay for antivirus software and to save money to buy a new smartphone such as a Google Pixel.

Quite a few applications allows you to "share" a file with them for media upload. If you want to, for example, tweet a picture to Twitter, do not grant Twitter access to your "media and photos", because it will have access to all of your pictures then. Instead, go to your file manager (documentsUI), hold onto the picture, then share it with Twitter.

With user profiles, you can impose restrictions on a specific profile, such as: making calls, using SMS, or installing apps on the device. Each profile is encrypted using its own encryption key and cannot access the data of any other profiles. Even the device owner cannot view the data of other profiles without knowing their password. Multiple user profiles are a more secure method of isolation.

### Google Play System Updates
### Обновление Google Play
In the past, Android security updates had to be shipped by the operating system vendor. Android has become more modular beginning with Android 10, and Google can push security updates for **some** system components via the privileged Play Services.
If you have an EOL device shipped with Android 10 or above and are unable to run any of our recommended operating systems on your device, you are likely going to be better off sticking with your OEM Android installation (as opposed to an operating system not listed here such as LineageOS or /e/ OS).
