The last words you want to hear when a government official is talking about the likelihood of the country being attacked by an enemy is a "matter of when, not if." Which is exactly what the National Security Agency chief said this week.
The director of the NSA, Adm. Michael Rogers, says the United States will be attacked by a foreign enemy. Topping his list of concerns is a cyberattack on the U.S. infrastructure.
We've told you about Iran hacking into New York state power plants a few months ago. State-sponsored hackers have also been found trying to damage other power plants.
You can imagine how many people would suffer or die if the power grid was shut down. Or if a nuclear facility was damaged, exposing millions to radioactive gas.
