PREACH!

Currently sitting in a control room at a greenfield manufacturing facility trying to describe why even VLANning the control network would be a good idea to some controls engineers who want a plant-wide subnet for all PLCs that will be remotely supported by 6 different vendors. The struggle is real

Loosely aware a controller manufacturer who wanted a bluetooth/wifi based password recovery utility with a fixed or predictable recovery key.

They were asked what their exposure would be if someone walked into a datacenter and used their phone to disable all the airconditioning systems.

Do they want the passwords for all their systems to match so they don't need to remember as many?

My suspicion is that they want all the passwords on this site to match the one they use with all their other customers too.

Saves money on password management.
