I'd like to have the legal department that lets that statement pass...

More likely.  But the device knows nothing about that.

The device does know what software runs on it.
Making that information available in the constrained space in such a way
that security automation can act on it is one of our immediate objectives.
(I'll probably talk briefly about this in next week's T2TRG meeting, in

draft for Buenos Aires.)
