Such is the conclusion in a recent piece for VentureBeat:
The U.S. is on the list of aggressors. Former U.S. Secretary of Defense Leon Panetta used to talk about the prospects of a â€œcyber Pearl Harbor.â€ He and other policymakers have fretted over the possibility that nation-state hackers might shut down parts of the U.S. power grid, blow up oil pipelines, contaminate the water supply, and even send airplanes on collision courses by hacking air traffic control systems.
Fortunately, no truly calamitous attacks have yet occurred in the U.S. In fact, the severity level of cyber incidents so far has ranked an average of 1.65 on a scale of 5, according to The Washington Post. A Level 5 is a threat to infrastructure, government stability, or American lives. The gravity of cyber attacks today is roughly similar to Russian attacks in the Ukraine â€“ they cause damage and are disturbing but remain far short of imminent danger.
In any event, the U.S. has no choice but to anticipate the worst.
