With the rapid development of computer technology, the business processed on the computer has also developed from a single computer-based mathematical operation, file processing, internal business processing and office automation based on a simple intranet to an enterprise-level computer processing system based on a complex intranet, extranet and Internet, and information sharing and business processing have spread all over the world.

While the processing capacity of the system is improving, the connection capacity of the system is also improving. However, with the improvement of connection information and circulation ability, the security problem based on network connection has become increasingly prominent. The overall network security is mainly manifested in the following aspects: network physical security, network topology security, network system security, application system security and network management security.
