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.
Even better is forcing changes every 30 or 60 days, and not allowing changes more than every week. Our users complain daily between those rules and the password requirements that they are too dumb to understand.
Password changes that frequent are shown to be ineffective, especially for the hassle. Complexity is a better protection method.
I’m aware. Apparently everyone who read my post has misread it. I’m saying that the requirements above are terrible, and they make my users complain constantly. Our security team constantly comes up with ways to increase security theater at the detriment of actual security.
