If there is widespread Chinese hacking of sensitive U.S. networks and critical infrastructure, what has the administration said about it to the Chinese government? Specifically, did President Obama raise concerns about these attacks with Chinese President Hu Jintao at the White House this spring?

Since defensive measures such as antivirus software and firewalls appear unable to stop the Chinese penetrations, does the administration have any plan to address these cyberattacks?

In private, U.S. officials admit that the government has no strategy to stop the Chinese cyberassault. Rather than defending American companies, the Pentagon seems focused on "active defense," by which it means offense. That cyberoffense might be employed if China were ever to launch a massive cyberwar on the U.S. But in the daily guerrilla cyberwar with China, our government is engaged in defending only its own networks. It is failing in its responsibility to protect the rest of America from Chinese cyberattack.
