Every day, America is attacked by foreign adversaries. These attacks don’t involve explosions, tanks, or fighter jets dropping bombs. Many times, they don’t even make the news. The enemy is rarely seen or identified. But none of this makes the threat any less real. The phrase “cybersecurity is national security” is often used, and perhaps even overused. Unfortunately, over the past few weeks, people have been exposed to the reality of that trope.

The Navistar International Corporation is the most recent American business to be targeted by a cyberattack. This follows similar attacks against the world’s largest meat producer, JBS, and the Massachusetts Steamship Authority. And these are only the attacks that made the news. Though most of them go unreported, millions of cyberattacks are attempted every day. Our nation is at risk.
