The default position will be that nothing and I mean nothing in the corporate domain will be able to open a TCP connection to anything in the SCADA domain.
and the guys in charge of this will take it all the way to senior management if you even look like you are thinking of breaking this rule.
and you'll have to sign some serious career limiting documents before the guys in suits will sanction this.
or at least that's how it's been at place I have worked where they have SCADA networks and my specialist topic is data integration so I tend to bump into these issues fairly often
It may have been a less advanced toolset, but the mindset back them was what really made it work. Back then, anything was possible, even expensive research unlikely to have any direct benifits. Now? If it isn't going to make a profit next month, trash it. Fuck the modern era. We did more with slide rules and determination than we do now with modern technology.
Nope re the mindset back then. I was coding for living back then and the ratio of good developers to bad developers is still pretty much the same now. Go and read the Mythical Man Month. What's sad is not that 'we were better at this stuff in the good old days' but that we, as an industry, haven't learned how to do things better having had 30 years of practice.
Always draw your curves, then plot your reading.
