Ni Guangnan, a computer expert and academician at the Chinese Academy of Engineering, said in a lecture that "Cyberspace has become the fifth territory after land, sea, air, and outer space. Like the other territories, cyberspace must also reflect the country’s sovereignty. To protecting cyber security is to protect national sovereignty."
In his view, both offensive and defensive sides to network security and information security exist. In this sense, independent ownership and control of core technology and equipment, information products, and services are a precondition to ensuring network and information security.
