IT & OT Language differences

As a control engineer that has worked on many systems involving business / enterprise data, I know the worlds of Engineering and Enterprise talk a different language to the rest of the world. They use the same words to mean different things. You would think words like production, operations, redundancy, real-time and uptime are clearly defined English words. However, you just need to spend a little 'real-time' trying to understand the world of which you are not normally a part to quickly understand that words mean different things. I now realise that even 'security' means something different. Security is not about strong passwords and firewalls, which can be, and are often, easily penetrated; an internet search on bypassing firewalls reveals a huge array of tools and easy methods. I recall a movie in which a boy found a cool game on the internet and thought he was playing space invaders, but he actually had control of real missiles. Security, to a manufacturing plant, is not about restricting access to users and information; it is about protecting assets. Security, in the control world, is about ensuring devices are operated when they should.

Data, and there is a massive amount of data in the control world, needs to be collected, aggregated and combined with other data. This is how it is transformed into useful information. It is necessary for this to be done in a way that protects our assets. Security is the main objection and often referred to as conservative approach to advancements in IIot, MES and MOM. The most secure product I know is the unidirectional gateway developed by Waterfall and available in Australia through Schneider Electric.
