In our second episode, we ask the question: “what is OT?”, and attempt to provide an answer. Join host Ken Kully, Cyber Tech Lead at Verve Industrial, and his guests and colleagues Lance Lamont, Tyler Bergman, Doug Artze, and Drew Wintermyer as they discuss what characterizes an OT environment and OT equipment, the impact of IT/OT convergence on distinguishing one realm from the other, and how a device’s usage is often the deciding factor as to whether it is an IT device…or an OT device. Key Takeaways: OT is the collection of hardware and software that is principally concerned with process availability: monitoring the process, providing safety oversight, and the automation, supervision, and control of the core processes for any industry. The same device can be both an IT device and an OT device, depending on usage. OT systems are often – though not always – characterized by device isolation, and can also be spread over a large geographic area. There are some industries – healthcare is an example – where the distinction between IT and OT becomes very blurred.
