A review of the history of human development shows that every major technological revolution brings new challenges to national security. With the advent of the information technology revolution represented by the Internet, cybersecurity has become an issue of paramount importance, and the digital intelligence revolution with digital technology innovations such as big data and cloud computing has further expanded the content and connotation of cybersecurity, which has been on a par with national security in the digital age. At present, the digital space has become an arena for competition between major countries. Against the highly uncertain security threats and risks in the digital age, joint governance or confrontation and split of the international community will determine, to a large extent, the future of human development.
