Abstract: The U.S. cybersecurity policy has evolved and developed a three-sided strategy synergy. Focusing on the protection of critical infrastructure in cyberspace, these strategies consist of cooperation between government departments and private companies, promotion of online public information sharing and coping strategies to protect the privacy and freedom of citizen information privacy. These solutions have been promoted to national strategies through a series of executive orders, administrative instructions, and federal laws. With the maturity of the U.S. network security policy, the current decentralized American legislation in this area can no longer meet the demand. The U.S. government and congress have actively promoted comprehensive cybersecurity legislation. On the other hand, China, as an important member of the international Internet economy and security system, has its own independent national interests and sovereign protection needs, which determines that China must have its own internal logical coherent Internet strategic framework and institutionalized system. Thus, the changes of the U.S. Internet strategy and legal system provide the most relevant reference for systemic thoughts on the construction of China's internet governance order, and so are worthy of absorption.
