The U.S. electricity grid is hard to defend because of its enormous size and heavy dependency on digital communication and computerized control software. The number of potential targets is growing as “internet of things” devices, such as smart meters, solar arrays and household batteries, connect to smart grid systems.
As researchers of grid security, we believe that current security standards mandated by federal regulations provide sufficient protection against observed threats. But recent incidents demonstrate the ongoing challenge of ensuring everyone follows the guidelines, which themselves must change over time to keep up with technological shifts.
