Brief introduction of network security review:

Network security review is a network security review system established in China. Its purpose is to discover and avoid the risks and harms brought by purchasing products and services to the operation of key information infrastructure as soon as possible, to ensure the security of the supply chain of key information infrastructure and to safeguard national security.

Network security review is different from assessment and certification, as well as universal review of foreign investment and national security review. Focus on whether there are threats or risks that affect the security of key information infrastructure and national security in network products or services. Cui Congcong, deputy director of the Internet Governance and Law Research Center of Beijing University of Posts and Telecommunications, once published an article pointing out that,

In recent years, cyber attacks on critical information infrastructure are on the rise all over the world, involving financial, medical and health, transportation, energy, industrial control and other fields, with a wide range of influence and serious degree. Carrying out network security review has become a common practice for countries to guard against the security risks of key infrastructure.

According to the National Security Law and the Cyber Security Law, in April, 2020, the National Internet Information Office, the National Development and Reform Commission and other 12 departments jointly issued the Cyber Security Review Measures.

The relevant person in charge of the National Internet Information Office once introduced when the Measures for Network Security Review was issued that China established a network security review system, with the purpose of discovering and avoiding the risks and harms brought by the purchase of products and services to the operation of key information infrastructure as soon as possible, ensuring the security of the supply chain of key information infrastructure and safeguarding national security.

Yin Libo, director of the National Industrial Information Security Development Research Center, once published an article pointing out that by conducting network security review, we can predict and check the network security risks that products and services may bring after they are put into use, prevent security incidents caused by product security vulnerabilities in the supply chain, and eliminate security risks from the source.
