As a result, brand new devices with old OS version and many known vulnerabilities – significantly raising the risk of exploitation – can be found on the market.
Only a few manufacturers provide periodical security patches and OS updates for their models, for different reasons.

FAQ is divided into several sections:Īs mentioned above, variety and diversity of devices running Android OS is a major security issue. VerifyApps, Google Play Protect) shall be omitted. Using third-party permission managers (such as XPrivacy) is strongly discouraged.įeatures dependent on Google services (e.g. Several enhancements've been introduced with every OS release, the last being Q right now. by Google Chrome browser.Īndroid Marshmallow and above implements an app permission model – user chooses to which files/components apps gain access. Android implements seccomp sandbox, providing advanced means isolation and higher degree of security. Each app's confined in its own sandbox ( IsolatedProcess), effectively being isolated from other apps and the OS. By default, apps can only be installed from a preinstalled app store – typically Google Play. Apps:Īndroid requires all apps to be digitally signed – unsigned apps won't run. Major enhancements regarding MAC have been introduced in Lollipop and Oreo releases.

Thanks to the MAC implementation, only a tiny portion of code now runs with full root permissions. SEAndroid considerably reduces the attack surface and also plays an important role in Android's permission model. MAC:Īndroid Kitkat and above uses a significantly modified Linux MAC implementation – SEAndroid.
Linux kernel arguably might not be the best choice from security perspective, but offers a decent permission model based on users and user groups, process isolation etc. Source: Android Security 2015 Annual Report Kernel:Īndroid's built on the Linux kernel. Each app's assigned their unique user ID and runs in sandbox, thus can't intervene with other apps and only is allowed to operate with files/OS components for which the user gives their permission. It uses the Linux kernel, implements a MAC and mitigations against memory corruption exploits – Android's the only linux distribution not supporting running non- PIE code. Android has a robust multilayer security model.
