If the company has to ask, is the network safe, it probably isn't. The only way to keep it safe is to remove outside connectivity in any way. But that doesn't stop the disgruntled internal ne're-do-well. All a company can do is stay current and respond to industry warnings. If in the process something else fails... what can be done? Isolation is the key.
There has never been a case of medical implant hacking, but it became a major panic for the med sector recently. Now they scramble to find solutions. Companies pop up to handle the phantom threat. In this case, is it really a concern? Or is it a case of better safe than sorry?
Thanks, Rob, a clear summary of the tensions between IT and the factory floor on this subject. Not only does connectivity and these conflicts affect a local network because of 24/7 use, it also affects everyone around the world in different time zones.

Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
