The emergence of network police is the result of the development of network security. Facing the severe network security situation, the network police must undertake the security work of supervising and managing the computer information system, which requires the network police to have higher political quality, professional quality, professional quality, cultural quality and physical quality.

Investigate and deal with illegal and criminal activities of illegally invading computer systems and destroying computer information systems according to law; It is also the most important work of the network police to master the development trends of public information network crimes, study the characteristics and laws of illegal crimes, and put forward countermeasures to prevent and combat public information network crimes.

Extended data:

The modern function of network police is the most distinctive feature of network police, because their duty is to search online to prevent and track the ghosts of various bad behaviors and criminal activities, which can be committed in a few seconds without leaving any traces.

Cybercrime is a high-tech crime. Compared with other crimes, it has the characteristics of concealment, complexity and internationalization. Network police should take the "rational use under strict control" of cross-border data flow as their own responsibility and increase the research and development of network security protection technology in China.

Strengthen the research on standardization of information security architecture, especially data encryption, key management, identity authentication, access control, data integrity and security audit. Because it is impossible to guarantee information security without corresponding security standards.

Actively track and absorb new technologies and ideas, make use of China's original key technologies, timely arrange technical-related scientific research projects such as firewall, monitoring, security key management, data encryption and security authentication protocol, and network information content screening, and independently or cooperatively develop network security products with independent copyright in China.
