SCADA Systems a Target for Hackers?

superstick58 writes "As a system integrator, I am often providing control solutions that utilize sophisticated Ethernet networks and as they say in the biz 'link top floor to shop floor.' Forbes has an article about the security issues that exist in SCADA systems. When I look back at some of the systems I have put in which include direct I/O control over ethernet and distributed HMI monitoring, if I can get access from the internet, it would be easy to bring down power for a plant or at the very least make operators in the building very uncomfortable. How vulnerable are the manufacturing centers of the world?"

My view..

I work in Big Oil. We have SCADA systems, we have an HMI to control the facilities, and it's all ethernet based. But the network is on a completley different wire than our internet-accessible network. You can't connect to the internet from our control network -- the wire simply doesn't exist.

And it shouldn't. They should stay separate. Period.
