I work for a company who designs SCADA networks for water/wastewater clients. We rarely connect the SCADA network to the internet, but when we do, it takes a lot of time and money to do it right. Hire a firm who specializes in SCADA security, you can't do it on your own.

Windows is used all the time for SCADA applications, especially in distributed control systems. SCADA applications aren't just embedded devices, they are typically a Windows server installed on a workstation that is used for the HMI (human-machine interface) used for operators to communicate with the SCADA devices such as PLCs and DCSs. Most operators would not be able to function without Windows so they can check their email on Outlook, surf the web or play solitaire. If you want to use programming and algorithms from major manufacturers, a Windows machine saves money since there are already drivers and plug-ins made for Windows machines.

In honor of Al Gore, it should be called ManBirdPig Flu.

I used to hit my gameboy all the time when I was mad at it, but I tried that a few hours after getting a Sony GameGear and it broke the screen!
