I agree that it's probably not as secure as it needs to be, but we don't know because the source is private. I'd like to see electronic machines with open source code, and open hardware. Off the shelf components. No custom chips. Let experts on either side inspect the machines before they're sent out. Verify all the code in all the systems against checksums. Verify hardware against schematics. Make sure there's a chain of custody when machines are shipped to poling locations. Have representatives from the participating political parties witness the receipt of machines. And so on.You write this post as if there was one breach of the credit agencies. I used to have an article from, maybe Forbes or Fortune, about five years ago that detailed fourteen major breaches of the credit agencies at that time.
I guarantee you that this election software is not world class security. We saw dozens of examples reported of how insecure it really is.
Some states do better than other states with how they conduct elections.
