According to a new report from MIT, the U.S. needs to work harder to prevent cyber attacks on its power grids.

"MIT researchers advocate for one government agency to shield the power grid from cyber-attacks, saying the current patchwork system leaves six million miles of electrical lines unprotected," writes Mobiledia's Kendra Srivastava.

"Many argue over the proper means to ensure the grid's safety," Srivastava writes. "For example, the Obama administration proposes the Department of Homeland Security handle power grid cybersecurity, while Congress says the Energy Department and FERC should stop hackers from attacking the U.S.'s electricity resources."
