WASHINGTON (Reuters) - Leading U.S. senators plan to introduce a cybersecurity bill on Tuesday aimed at safeguarding the nation's water and power systems, which experts have warned often only have the most rudimentary protections against hackers.
Senators John Rockefeller and Dianne Feinstein, both Democrats; Susan Collins, a Republican, and Joseph Lieberman, an independent, have drafted a comprehensive bill that would require the secretary of homeland security to designate certain infrastructure as critical and compel steps to safeguard against hackers.
"The prospect of mass casualty is what has propelled us to make cybersecurity a top priority for this year, to make it an issue that transcends political parties or ideology," Rockefeller told the Senate on Tuesday morning.
He noted hackers' success in breaking into sensitive government agencies and Fortune 500 companies, and warned that air traffic control, rail switching networks and chemical pipelines could be the next target.
"We can act now and try and prepare ourselves as best as we can, or we can wait and we will be surprised with what happens. I'm here to argue that we should act now," Rockefeller said.
The legislation would also ease information-sharing between the federal government and the private sector to combat cyber crime and espionage, and would require the government to take steps to secure its own networks.
Last, it would update recruitment of cybersecurity experts into the federal workforce.
Senate Majority Leader Harry Reid last year called for the drafting of a comprehensive cybersecurity bill, and this 207-page bill is the product. Reuters obtained a copy.
Defense contractors such as Lockheed Martin Corp have been among the high-profile victims of cyberattacks. Others include Google, Citigroup and Nasdaq OMX.
Industry has fought back and succeeded in stopping previous cybersecurity bills, even though experts have warned for years that portions of the U.S. critical infrastructure -- particularly water and electrical plants -- have only rudimentary defenses against hackers.
Industry opposes additional regulations as burdensome and argues it should focus on fighting hackers instead of complying with government rules.
The House of Representatives is considering legislation that overlaps with the Rockefeller bill on some points.
Republican Representative Mac Thornberry, who oversaw the writing of a report outlining Republican priorities, supports regulation to require better cyber defenses for critical companies.
A key difference would be that the companies' usual regulator would oversee the new regulation rather than the Department of Homeland Security.
