Conclusion

Application of the Flask architecture to the X server is a key security development that provides a foundation for securing the Linux desktop. Vigorous work on the projects described in this paper and in other userspace object manager and desktop-related areas is expected in the coming months of 2007.

As mentioned, the XACE framework has been accepted into the X.org mainline for release 1.2 of the X server. The current, tentative target for acceptance of the Flask module is release 1.3, which is scheduled for mid-2007.
