LinuxKernel > SELinux

Security-Enhanced Linux (SELinux) is a project to implement mandatory access control under Linux. This project was initially developed by the National Security Agency (NSA), as a reference implementation.

For more information please check out the SELinux project's homepage or wikipedia.

Debian SELinux support

The Debian packaged Linux kernels have SELinux support compiled in, but disabled by default. To enable it, see the Setup Notes.

Non-Linux Platforms

Please note that SELinux is a Linux-specific feature and Debian packages shouldn't assume it is present (unless they're Linux-specific packages for some reason). Note for developers: Remember to check whether this is a Linux platform by using dpkg-architecture variables in debian/rules, and conditionalise the libselinux Build-Dependency using [] tags. Something like [linux-any] should be fine.

Mailing lists

There is a mailing list about SELinux development in Debian hosted on alioth. Use the selinux-devel Mailman page to subscribe to the list or browse the archives. As we don't have a user list you can ask questions on usage there.

The upstream SELinux Reference Policy maintenance is coordinated on the Reference Policy mailing list.
