The Flask architecture demonstrated in the security enhanced Linux® reference implementation has been ported to several other operating systems, including the Solaris operating system, the FreeBSD® operating system, and the Darwin kernel, has been ported to the Xen hypervisor, and has been applied to applications such as the X Window System, D-BUS and PostgreSQL. The concepts of the Flask architecture are broadly applicable to a wide range of systems and environments. Some of these related efforts have been described in the papers and slides available on the documentation page, and some have been mainstreamed into the respective upstream projects. Links are provided below for some of these related efforts that have their own external project site.
