Even if they could do it, very few ICS admins would switch to it. Most people there are responsible for stability as their most important attribute - and that means running a solution that has proven itself over and over and over again. Related to this concern is downtime: often times these plants are running 24x365 schedules, controlling furnaces that keep ovens full of molten iron from freezing solid, which could destroy the oven. Shutting down a production line takes time and planning to prevent damag. Even if they could do it, very few ICS admins would switch to it.

Related to this concern is downtime: often times these plants are running 24x365 schedules, controlling furnaces that keep ovens full of molten iron from freezing solid, which could destroy the oven. Shutting down a production line takes time and planning to prevent damage, and every minute that line is down, they are not making money. What they actually need to do is to really isolate these control systems in the hard sense. No ports network, data import only manually, data export via CD-R or the like, clear message to employees that connecting any USB media, Laptops, etc. Will result in immediate termination. It can be done, even if it may require some people to suffer first, as Iran found out.

After upgrade the View Studio work fine, but Studio 5000 give me a week of work. I tried to downgrade Factory Talk Activation to version 3.51 follow the procedure and View Studio is in Demo mode (5 displays!!), but Studio 5000 works fine. (h) So I can use one properly only one program. Do you have any. Only the RSLogix 5000 MLP Option product has been activated. Perform activation process for Studio 5000 software itself. Necessary information (serial number and product key) is included in activation certificate. For more information see. This knowledge base web site is intended to.

They did execute the people that imported Stuxnet via USB drive. My guess is they will not have that problem again anytime soon. When there is a credible threat, they look at addressing the threat on an individual basis. Firewalls between the controller and the LAN.

Epoxy in the USB ports. A locking cabinet around the CD-ROM drive. But replacing the core of the factory, on an unproven software package, just 'in case' a hacker might target them?

Not terribly likely. This is not enough. Firewalls are insufficient. They need to implement real isolation, i.e.

Bandini Serial Last Episode. Only an isolated net may be used and that has to be very heavily protected. It will take quite some time for them to find out how to do that, although competent IT security people could tell them today.

The problem is that they are asking the wrong questions and are looking for IT experts that understand their business, instead of looking for competent IT security folks. And the further simplistic (but still dumb and vulnerable) solution for you might be 'two laptops'. Only the red laptop connects to the equipment.

The other laptop connects to the Internet and lets you read the manuals, docs, slashdot, etc. If you need to download a file, you format a flash drive in the red laptop, insert it into the black laptop and copy the file, then read it back in the red laptop. It's cheap enough, and adds another layer of difficulty. It might not have stopped Stuxnet, but it wou. Speaking as the system administrator for a large DCS system: the OS will be no good without a complete redesign of the application level software. The problem is not really the OS, but the fact that in order to make everything work together 'automagically', there are hardcoded service accounts, and much of the app executables (which are often executed with system permissions) are writable because the entire installation folder is writable. And of course, the controllers that do perform all control actions use a protocol whose only real claim to security is obscurity.

And from what I can tell, the system I manage is fundamentally no different in that regard from DCS or SCADA systems from other vendors. While it is true that a secure-by-design would be a good place to start, the main problem atm is that the application architecture is hopelessly insecure. Having recently switched fields from high-end telecom gear to industrial machinery, I can confirm this. The industry works with what hardware they know.

I last worked in the field two decades ago, and now I see the same Cutler-Hammer contacts, the same Schadow switches, the same Schroff and Rittal metal works, the same Panduit wire ducts, the same Oriental motor drives, the same Allen Bradley PLCs. Oops, that PLC now has an ethernet port? The PLC looks the same as before, a grey box covered in screw terminals, but apparently it must have changed from a 6809 running GRAFCET to some sort of modern porous monstrosity needlessly running a 64 bit OS with so much unverifiable code. It's not necessary. I like to compare the problem in this industry to Powerpoint presentations. If you ever attend a university lecture, you'll see the professor, who is an engineer, doctor, master's, Ph.D or whatever.
