Right, but you would think that an organization with the kind of
operational security needs that they would go to the lengths of installing
a separate physical network would have their systems on that network locked
down to prevent ANY form of removable media - whether it's used for
installation of an OS or storage of documents due to various threats and
the idea of preventing data loss/leakage.

As to your thought on connecting to a possibly infected system -
organizations that go to these lengths would most likely also install brand
new hardware on that network to mitigate that risk.  Of course, it's
possible that those systems would come from the factory with something
onboard (which is the big knock against Lenovo at this point) to allow for

At this point, the only real way to mitigate and eliminate every risk would
be to leave the systems in the original shipping container, surrounded by a
Faraday cage, in a locked room with no lights or windows a single door
locked, welded shut, surrounded by thermal, IR and visual spectrum cameras,
barbed wire, land mines, a moat filled with flesh eating bacteria and
patrolled by a vampire bunny with a hangover, a .45 and a bad attitude.
But, since that would put a slight crimp in worker productivity...
