China prepares to block US cyber attacks

"We are in the early stages of a cyber arms race and need to respond accordingly," Washington Times

China has developed more secure operating software for its tens of millions of computers and is already installing it on government and military systems, hoping to make Beijing's networks impenetrable to U.S. military and intelligence agencies.

The secure operating system, known as Kylin, was disclosed to Congress during recent hearings that provided new details on how China's government is preparing to wage cyberwarfare with the United States.[...]

The deployment of Kylin is significant, Mr. Coleman said, because the system has "hardened" key Chinese servers. U.S. offensive cyberwar capabilities have been focused on getting into Chinese government and military computers outfitted with less secure operating systems like those made by Microsoft Corp.

"This action also made our offensive cybercapabilities ineffective against them, given the cyberweapons were designed to be used against Linux, UNIX and Windows," he said.

The secure operating system was disclosed as computer hackers in China - some of them sponsored by the communist government and military - are engaged in aggressive attacks against the United States, said officials and experts who disclosed new details of what was described as a growing war in cyberspace.
