Security Enhancements (SE) for Android™ was a NSA-led project that created and released an open source reference implementation of how to enable and apply SELinux to Android, made the case for adopting SELinux into mainline Android, and worked with the Android Open Source Project (AOSP) to integrate the changes into mainline Android. As a result, SELinux is now a core part of Android. See for further information on SELinux in Android.

SE for Android was originally called Security Enhanced Android (SE Android) but was renamed to comply with the Android brand guidelines. Hence, you will see the older name in many of the presentations and papers below.

SE for Android used to maintain its own source code repositories on but these have been removed since the code has all been merged to AOSP.
