Chamber not sold on revised cybersecurity bill

In the original version of the bill, that section would have required companies operating critical infrastructure such as water systems and power companies to meet a set of security standards. A group of GOP senators and the Chamber said these provisions would saddle industry with burdensome regulations and add another layer of bureaucracy to existing security structures.

Lieberman amended that section in the revised bill to allay those concerns.

Beauchesne said Congress should focus on passing bills "where consensus has already been reached," such as measures aimed at boosting cybersecurity research and development and improving information sharing about cyberthreats. The Chamber has backed the Cyber Intelligence Sharing and Protection Act in the House and a rival cybersecurity bill by Sen.

"Congress is getting bogged down – and rightly so – on the issue of regulating business because there remains considerable disagreement on this topic," Beauchesne added. "The Chamber and many other stakeholders view government-driven compliance regimes as costly to taxpayers and businesses and contrary to effective security."

The Chamber's opposition to the revised bill could discourage some GOP senators from backing it.

Lieberman and the bill's four co-sponsors have argued that cybersecurity legislation must include provisions aimed at addressing security gaps in the computer systems and networks of critical infrastructure.
