The hurried deployment of smart-grid technology could leave critical infrastructure and private homes vulnerable to hackers. Security experts at the Black Hat conference in Las Vegas last week warned that smart-grid hardware and software lacks the necessary safeguards to protect against meddling.
Utilities are being encouraged to install this smart-grid technology—network-connected devices to help intelligently monitor and manage power usage—through funding from the U.S. government's 2009 stimulus package. The smart systems could save energy and automatically adjust usage within homes and businesses. Customers might, for example, agree to let a utility remotely turn off their air conditioners at times of peak use in exchange for a discount.
But to receive the stimulus money, utilities will have to install new devices across their entire customer base quickly. Security experts say that this could lead to problems down the road—as-yet-unknown vulnerabilities in hardware and software could open up new ways for attackers to manipulate equipment and take control of the energy supply.
