That's esentially wrong. Windows does support Discretionary Access 
Control which, althogh it's a little bit more advanced than UNIX DAC, 
it's not Mandatory Access Control. Don't get confused: SELinux is 
Mandatory Access Control, while uid/gid/masks are Discretionary Access 
Control.

They are such different beasts: With DAC, permissions over resources 
are managed by their owners (root or users). In a MAC-based system, a 
policy governs how the system security behaves, and the policy is set 
up by an administrator and obeyed by everyone.
