One chestnut from my history in lottery game development:
While our security staff was incredibly tight and did a generally good job, oftentimes levels of paranoia were off the charts.
Once they went around hot gluing shut all of the “unnecessary” USB ports in our PCs under the premise of mitigating data theft via thumb drive, while ignoring that we were all Internet-connected and VPNs are a thing, also that every machine had a RW optical drive.
Thought my work was bad. We at least can use VMs. I literally can’t do my job without one, Rockwell being what it is. Companies don’t like upgrading PLC software so I need to use old versions of windows occasionally to run old Rockwell stuff.
There was also a bug for a bit that would brick win11 PCs when trying to update PLC firmware, fun stuff.
