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.
As a security guy - as soon as I can get federal auditors to agree, I’m getting rid of password expiration.
The main problem is they don’t audit with logic. It’s a script and a feeling. No password expiration FEELS less secure. Nevermind the literal years of data and research. Drives me nuts.
