Re: 3 levels to the plant

Ann, vendors from companies like Rockwell and Siemens say that this arrangement has effectively solved the problem of the conflict between control and IT. The goal apparently is for everyone to take the side of the company and not the side of control or IT.

Good point. But if that means shutting down the plant unscheduled, that can run into considerable dollars.

Sometimes it is important to install patches in a timely manner, particularly if a new expoit is a zero day.  So it boils down to this:
A hacker or an exploit takes down your plant.  Who are the executives and shareholders going to lynch, IS or the plant management?  I can tell you it will be IS, and the argument will be that IS didn't explain the urgency clearly enough (which they did, but were ignored), and that IS is ultimately responsible for computer security.

Cabe, this problem will grow as plants continue to shift to wireless devices. It's one thing to protect a wired network, but a wireless network is even more vulnerable. Wireless is attractive because is costs less and you can put a device in places where it's hard to run wire.

One of the clashes between control and IT is that IT wants to update the patches more often than control has scheduled downtime. So, to meet IT's desired updating, control would have to shut down the plant more often.

No system is 100% safe even with safeguard protocols in place. I expect the problem to continue to grow as mobile devices become more powerful in terms of tech.

I see your point, AnandY. The mandates of IT and control are absolute. For IT, no security breaches. For control, no downtime. I've heard vendors talk of peace between the two when a committee is set up to solve these issues and both IT and control are represented on the committee.

At least when IT takes down services to install patches, it should be a scheduled maintenance period.  Hackers don't care about schedules.  I'd rather have a scheduled downtime to install patches than unscheduled downtime because I couldn't.  But as I read the article it emphasizes the trend that users are pushing technology into the work environment without understanding the implications.  IT must have time to evaluate the risk and do what they can to minimize it.  If it cannot be eliminated completely, IT needs to communicate their concerns to management.  Then, if management decides to sign off on the risks, IT has done their due dlilgence and responsibility now rests on management.  But again, IT must have time to research and test the technology in their environment.  This is no different than the standards of good manufacturing and design:  R&D and QC.

 Working a truce between the IT and control department seems logical but I think it is more theoretical than practically possible. If the teams couldn't work out an understanding on their own I don't see how they will when sat down together on a round table. Their mantras dangle on the opposite sides of the seesaw thus for the prosperity of one the other will have to take a blow in the neck.

Point well taken, Digerati Ohm. But it works both ways. IT has to understand the plant can't shut down in order for IT to install a patch at 2:00 am. That works for the office PCs, but not for the plant PCs if the plant runs 24/7. I think both conrol and IT have an issue with outside devices. But often the clash between IT and control doesn't have anything to do woth outside devices. it has to do with conflicting mandates.

We shared our list, now Design News readers tell us which artificial intelligence movies they watch again and again.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
Researchers have simplified the fabrication of the geometric requirements for fluid motion in microrobots for in vivo medical applications.
The National Aeronautics and Space Administration’s recently announced plan to put an electric airplane in the air by 2018 is forward-looking, but hardly unique.
