Saying "protect data" is nearly meaningless without a threat model.
I bet you don't try to protect data from a direct nuclear hit, or a
court order.


AA has a fairly clear threat model. It involves a flaw in a
program being used by an external agent to cause it to use
privileges it would not normally exercise to subvert privacy or
integrity.
I think this model matches a lot of real threats that real sysadmins
have real concerns about. I believe that the design of AA addresses
this model quite well.

What is your threat model? Maybe it is just different.
