Flask operating system
Encyclopedia
The Flask operating system architecture is a joint venture between the National Security Agency
, the University of Utah
, and the Secure Computing Corporation project designed to provide a framework for a more secure operating system
. Development and implementation started with the Mach
microkernel
, and has since shifted its focus to the Linux
operating system. It is now better known as Security-Enhanced Linux
(or SE Linux).
