This MAY detect that the program operates correctly (which is more difficult 
than you may imagine in the case of programs that launch other programs in 
different domains - think of checking password access by pam_unix.so).  
However it does not help for the more difficult problems, such as determining 
that the program is not given excessive permissions.

Many programs routinely try to access things that they don't need, one of the 
most difficult parts of writing SE Linux policy is deciding when to use a 
dontaudit rule for such things.

I've been trying to encourage post-grad students to do a Ph.D thesis on a 
related topic.  So far no-one has been interested.  It's generally regarded 
that this problem is not solvable in the general case, but I think that a 
good Ph.D project could get a usable partial solution.
