You probably heard about the false alarm in Hawaii over the weekend, warning that a ballistic missile was on the way and to take shelter. This Facebook video captures reaction of those who experienced it. The issue was human error.
And it is not the only "panic causing" false alarm in the U.S. this year.
In fact, on January 3, 2018, a town along the Oregon Coast received voice warnings from speakers on towers that a tsunami would be arriving in four hours. As The Daily Astorian found out, people were evacuating and the issue here was a computer glitch.
And then there was Dallas, Texas, in 2017, where hackers set off tornado warning sirens in the middle of the night just for fun.
In all of these cases, reversing the warnings took much longer than issuing them.
We now reach nearly everyone, everywhere, instantly—through our connected world.
And Bob Sullivan argues in his writeup today that it is crucial we get warnings right and protect the systems that control them because each false alarm (regardless of what went wrong) exposes weak points which hackers would love to exploit.
