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.
Pretty sure it’s some misapplied heuristics for previously identified bad clients, but that should only trigger an alert (with details!) in most cases and not block you if it’s not also paired with any known malicious activity
I’m going off memory from early 2021. But it was my private IP on the laptop using a Class B private address according to their support team. I was flabbergasted. Maybe they just expected every remote worker to use Class C or something. Who knows?
