America's declared (and undeclared) cyberwar

摘要

President Barack Obama issued an executive order in mid-February to make it easier for "eligible critical infrastructure" companies and the US government to share information about network attacks. As the international cyberwar heats up, the executive order represents one of several ways the US government is attempting to protect national interests from network attacks and data theft. It is also the latest development in the United States' reaction to increasingly common attacks that could have major implications on the world's supply chain. The main goal of the executive order is to create more efficient best practices and policies for protection against "the cyber threat to critical infrastructure, which continues to grow and represents one of the most serious national security challenges we must confront."
