A pair of senators including Maine's Sen. Angus King is renewing its efforts to get protections for the country's energy infrastructure against cyber-attacks.

King, an independent, is partnering with Idaho Republican Sen. Jim Risch on the push to pass the Securing Energy Infrastructure Act. They say the proposal seeks to examine ways to defend the energy grid.

The senators say their approach would look at replacing devices such as computer-connected operating systems with analog and human-operated systems. They say that would leave infrastructure less vulnerable to cyber-attacks.

The senators reintroduced the legislation on Tuesday. It was introduced last year as well.
