FCC unveils updated online cyber tool for small businesses

"While broadband is creating significant opportunities for small businesses, the cost of cyber attacks are a real concern," Genachowski said in a statement. "We know that not having a plan leaves small businesses vulnerable to cyber attacks."

Nearly 10,000 businesses have used the tool since Genachowski first introduced it last year, according to the FCC. The agency partnered with Symantec, eBay, Visa, the Department of Homeland Security and others on updating the online cybersecurity tool.

A new study from Symantec found that small businesses are particularly vulnerable to cyberattacks, as nearly 83 percent of them lack plans on how to secure their computer systems and networks from hackers.

The FCC also released updated recommendations on how small businesses can better secure their workers' mobile devices and thwart fraudulent payments from nefarious actors.

Boosting the nation's cybersecurity has been a top concern of the Obama administration as the cyber threat facing the U.S. rises. Defense Secretary Leon Panetta warned in a speech last week that the U.S. could face a "cyber Pearl Harbor."
