【Abstract】 Network information system is based on computer and data communication network. The security of network information system is studied in this paper. First, the factors that affect the system security are introduced, and the basic requirements of security are also proposed. Furthermore, some technologies that are used to enhance the security of network information system are studied, such as network security, operation system security and data security and so on. Finally, it is pointed in this paper that the system security must be insured only if the appropriate technologies can be used and the system can be rigorously supervised.更多还原
