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.
That’s super true, so many times to stay ISO compliant (I’m thinking about the lottery industry here), security policies need to align with other recommendations and best practices that are often insane.
But then there’s a difference between those things which at least we can rationalize WHY they exist… and then there’s gluing USB plugs shut because they read about it on slashdot and had a big paranoia. Lol
