Sen. Joseph Lieberman (I-CT) is proposing legislative measures to be incorporated in a bill expected from Sen. Majority Leader Harry Reid (D-NV) that among other provisions would potentially grant the Department of Homeland Security extraordinary regulatory powers over critical infrastructure including the Internet.

A draft of Lieberman’s proposed measures, dated Jan. 27, 2012, was obtained by Breaking Gov.

While subject to revision, the proposal attempts to define what constitutes critical infrastructure and if passed, would grant DHS relatively unchecked authority to promulgate its own regulations. Those regulations would be subject to undefined “enforcement actions” by the Secretary of Homeland Security and other agencies that may have regulatory authorities over the companies in specific economic sectors.
