Go find a company that writes process control software (preferably the one they plan to use) and talk to them. Ditto goes for SCADA systems, many of which have tcp-ip capabilities, with many now having capabilities such as emailing reports, directly from RTU's!. Generally speaking the security on this stuff is bad, the primary method being to seperate it heavily, which may or may not work (dialup, VPN's, etc.).
