Did people think that not connecting to a network was a magic technique that prevented infections from being spread on USB drives if you move them back and forth?
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.
It was maddening.
There are other adverbs.
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.
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.
