Bottom line is every major organization has been breached, your data, research, ID are already in the wrong hands, most of what's being done now (network access control, intrusion detection, Antivirus, firewall, etc..) is to satisfy the legalities and not get sued... And yet we keep buying smart devices all around our homes and doing everything online, and I bet our nuclear power plants computers have web access too...
I'll repost this, and replace voting software with ANY software... even that of your smart fridge.
