No but it’s a good start. The problem is that literally everyone would do it, from directors to the lowest paid people on the job. EVERYBODY does it. We detected and blocked, so then they started hardwire connecting to switches that they saw in offices. We had blocked those, so they started trying to connect to industrial switches out in the factories.

Ensure the kernel filters out all USB except for the major/minor used by mice and keyboards. This is absolutely standard for secret-squirrel shit. Default to rejected, but allow a few.
This was a long time ago in a different world. I’m an old man now. My job now is coaching soccer and gardening and baking, but thanks for writing that. Hopefully new admins see it.

It was maddening.
There are other adverbs.

And it was literally.
There are ‘keyboards’ that when plugged in type Win+R CMD.exe then do whatever you want. (Other terminals are available)
I guess that stops users from trying in the first place though.
But switches have all ports set to shut and open ports bound to the device connected… or is this not common?
It depends on the environment for sure. That was standard at the end of my career but definitely not at the beginning.
