I used to work with a guy who glued the USB ports shut on his labs. I asked him why he didn't just turn them off in BIOS and then lock BIOS behind a password and he just kinda shrugged. He wasn't security, but it's kinda related to your story.
¯\_(ツ)_/¯
Security where I work is pretty decent really, I don't recall them ever doing any dumb crazy stuff. There were some things that were unpopular with some people but they had good reasons that far outweighed any complaints.
I completely hear you.
When they did this for the stated reason of preventing data theft via thumb drive, the mice & keyboards were still plugged into their respective USB ports, and if I really wanted I could just unplug my keyboard and pop in a thumb drive. Drag, drop, data theft, done.
Further to this madness, half of the staff had USB hubs attached to their machines within a week which they had purchased at dollar stores. Like...?
At any time, if I had wanted to steal data I could have just zipped it and uploaded it to a sharing site. Or transferred it to my home PC through a virtual machine and VPN. Or burned it using the optical drive. Or come up with 50 other ways to do it under their noses and not be caught.
Basically just a bunch of dingbat IT guys in a contest to see who could find a threat behind every bush. IT policy via SlashDot articles. And the assumption that the very employees that have physical access to the computers... are the enemy.
Okay I'll concede that SOMEWHERE in the world there exists a condition where somebody has to prevent the insertion of an unauthorized thumb drive, they don't have access to the BIOS, they don't have the password, or that model does not allow the disabling of the ports. No other necessary devices are plugged in by USB. Policy isn't or can't be set to prevent new USB devices from being added to the system. And this whole enchilada is in a high-traffic area with no physical security and many with unknown actors.
Right.
Gotta put something good on the monthly/ quarterly activity report/personnel review!
I just wrote a script that let me know if usb devices changed and emailed me. It was kinda funny the one time someone unplugged a USB hub to run a vacuum. I came running as like 20 messages popped up at once.
