While physical threats to the U.S. power grid and pipelines have long worried policymakers, cyber threats to the computer systems that operate this critical infrastructure are an increasing concern. Cybersecurity risks against the power and pipeline sectors are similar, as both use similar control systems, and there appears to be a broad consensus that cyber threats to this infrastructure are on the rise. Furthermore, with ever-greater physical interdependency between electricity generators and the natural gas pipelines that supply their fuel, many in Congress recognize that grid and pipeline cybersecurity are intertwined. In 2015, the Fixing America’s Surface Transportation Act (the FAST Act) provided the Secretary of Energy with new authority to protect or restore the power grid during a grid security emergency, including a cyber incident. Congress is considering additional legislation to fund and expand the Department of Energy’s cybersecurity programs.
