In a control.com thread, Walt Boyes and I were dueling over network security in the industrial arena and the role of IT. Walt busts out with this "revolutionary edge peripheral firewall ", the Tofino device. I come back expressing interest in the idea, noting that IT should still be involved in such matters since they understand the technologies.
I emailed Walt about giving permission for his quote (which is located above mine). His response, "As a public figure I don't have a choice about being quoted, but I'd prefer that they say what I actually did, especially when it is written down (like in my blog)."
My quote was a little farther off - see transcription below. Walt emailed the company. I haven't decided on my next move yet. I really should have said "idea" instead of "thing".
(Walt)> Then he put the Tofino firewall in the line between the network and the PLC, and the PLC absolutely disappeared to the blackhat software.
That's what a firewall does. I think the Tofino device is a cool thing - it allows a PLC type who has no idea what he's doing with networking or security to provide some amount of protection to the plant floor - an innovative idea. However, a good IT department would do better. Worst case they could work with you on configuring that device, and actually understand what's going on. "
