I heard a news story that many information system about rivers and dams are under danger of cyber attacks.
I wondered why local governments choose the Internet instead of leased line or VPN. It's probable the matter of cost.
I also wondered that why the news source would too much focused on the Internet to which basically everyone can connect, instead of private networks
Well, with this those who are not familiar with computer network are likely to confuse the Internet with computer networks of any kind, and think that "Computer Networks are dangerous."
Things we can do is know the risk of connecting to the Internet where everyone connect, especially using it a tool of shopping, or use as a public information tool, and know what we can trust and what we can pass when the connection is not totally trustworthy.
