Taking the Cyberattack Threat Seriously
Last month I convened an emergency meeting of my cabinet and top homeland security, intelligence and defense officials. Across the country trains had derailed, including one carrying industrial chemicals that exploded into a toxic cloud. Water treatment plants in several states had shut down, contaminating drinking water and causing Americans to fall ill.
Our nation, it appeared, was under cyber attack. Unknown hackers, perhaps a world away, had inserted malicious software into the computer networks of private-sector companies that operate most of our transportation, water and other critical infrastructure systems.
