Is cyber-hacking the greatest threat to a modern, networked nation?
Over the past few months, the discoveries of two engineers have led to a steady trickle of alarms from the Department of Homeland Security concerning a threat to the nation’s power grid. Yet hardly anyone has noticed.
The advisories concern vulnerabilities in the communication protocol used by power and water utilities to remotely monitor control stations around the country. Using those vulnerabilities, an attacker at a single, unmanned power substation could inflict a widespread power outage.
Still, the two engineers who discovered the vulnerability say little is being done.
