<a href="#firewall">Does GrapheneOS provide a firewall?</a>
</h3>
<p>Yes, GrapheneOS inherits the deeply integrated firewall from the Android Open
Source Project, which is used to implement portions of the security model and various
other features. The GrapheneOS project historically made various improvements to the
firewall but over time most of these changes were been integrated upstream or became
irrelevant.</p>
<p>GrapheneOS adds a user-facing Network permission toggle providing a robust way to
deny both direct and indirect network access to applications. It builds upon the
standard non-user-facing INTERNET permission, so it's already fully adopted by the app
ecosystem. Revoking the permission denies indirect access via OS components and apps
enforcing the INTERNET permission, such as DownloadManager. Direct access is denied
by blocking low-level network socket access.</p>
