the real problem here is that they should have had two distinct networks, one for their payment system that is wholly separate from all other network activity.

Its boggling to me that any company would permit another company on the same network when their work is wholly unrelated.

Not really, you've got a store manager who wants instant access to the same refrigeration alarms and control system his vendor sees and live sales figures all from the same PC. I can totally see it happening.

Wholly unrelated would be the Target store manager (or district mgr or whatever) having access to Walmarts backup generator telemetry.
