As general secretary of the CPC Central Committee and president of China, Xi Jinping proposed efforts to promote innovative development, and work hard to build China into a cyberpower. Critical information infrastructure protection is one of the most important parts of the network strategy. We should learn from other countries, especially developed countries, to secure our critical infrastructure while we are still in the early stage. The United States, as the first country devoting attention to protect critical infrastructure cyber security, has developed a set of critical infrastructure information security policies, measures and supporting works. The study will provide suggestions for our critical infrastructure defense by reviewing American critical infrastructure measures from the perspectives of its identification, management system and security requirement.
