Re: This is another example of why cyber so-called security is nigh on impossible for average Joe
Literally how I presented cybersecurity to a school's management, staff, etc.
We can't defend against it. We absolutely cannot. We can do some stuff but so much is just generic computing nowadays that I'm far more reliant on staff not clicking an email than Microsoft not screwing up the system. Our security is literally in the hands of untrained random people.
We can only hope to "outrun the other guy being chased by the bear". That's it.
If we were ever particularly targetted... we're dead in the water. Even our cyberinsurers agree on that. All we can do is hope to stay under the radar, not give off "we have dumb IT" vibes on our websites and services, and cross our fingers.
The only real solution is a return to actual, limited, permissioned IT. You want to add a student record? Press 1. You want to Edit? Press 2.
If you don't limit the interface, but instead every doughnut is running a full Windows OS with a thousand apps and programs, with access to huge Sharepoints and OneDrive and clicking on thousands of emails in a program that automatically opens them in whatever it feels like.. it's already game over.
The old terminal system I used in an international haulage firm 30+ years ago as part of my work experience was infinitely more secure than anything we have nowadays. You could only press certain buttons. You could only do certain things. You could only do that from certain locations. It worked. Everyone had what they needed and nothing more.
I remember them - at the time - trying to show off their new (Windows 95/98?) machine and how it was the future of their business and even as a geeky kid back then... I was thinking, that's not a great idea. So now everyone is "running as admin", everyone can modify all files on that drive, and it's full of nonsense like Active Desktop and loaded up with games, etc. I honestly had to do a kind of "Yeah, that sounds... interesting" thing when they kept crowing about how wonderful it all was that they would have different desktop backgrounds etc. And all I could think of was the number of times that my classmate and I had compromised my school's 3.1 / Netware / 95 network repeatedly with some stupendously simple things (literally "admin-rights" on Netware and complete control of the machines... I'm not joking).
Sorry, but general purpose computing and cloud computing too... they are basically just huge great bullseyes on all our backs. We're not going to get away from that. It's like trying to lock up a prisoner who is allowed to do anything they like, and roam anywhere they like, and interact with anyone they like, and bring in any visitor they like...
