China is, of course, not the only source of cyberthreats. They come, too, from Russia, Iran and elsewhere, including domestic hackers. Congress has long been aware of the problem and has sought for at least the last two years to pass legislation that would facilitate information sharing and cooperation between private corporations and the government. Maryland's Rep. Dutch Ruppersberger, who is the ranking Democrat on the House Intelligence Committee, has been in the middle of the effort, along with Republican Rep. Mike Rogers of Michigan, who chairs the committee. Their bill, the Cyber Intelligence Sharing Protection Act, or CISPA, passed the House in April on a bipartisan vote, 288-187.
