Congress rethinks power grid cybersecurity

Concerns about a cybersecurity attack on the nation's electric power grids are being raised in Congress, with lawmakers considering legislation to broaden federal authority over electric companies.

"I believe America is disturbingly vulnerable to a cyber attack against the electric grid that could cause significant consequences to our nation's critical infrastructure," said Rep. James Langevin (D-RI). Industry representatives, also testifying at the congressional hearing, conceded there is a need to strengthen federal authority to deal with the cybersecurity threat. They also cautioned against expanding the government's powers too broadly.

Rep. Rick Boucher (D-VA) said the proposed law could require any owner, user, or operator of the bulk power system to abide by interim measures imposed on short notice by the government to address security threats rather than waiting for completion of lengthy rule making proceedings. Federal Energy Regulatory Commission chairman Joseph Kelliher said this authority should apply to a broad definition of national security threats that would include both physical attacks and cyber attacks.
