Research on security structure of scientific and technical information system

As the dedicated information system, scientific and technical information system plays an important role in work; the continuous updating and development of the system needs a scientific and systematic security structure to guide its secure administration and running. The article, which starts the research on the relevant issues with respect to the theory and technology of security structure of scientific and technical information system, puts forward the design principle on security structure of scientific and technical information system, establishes a security structure model taking application environment as the subject, makes an analysis on the application environment of security structure model, and establishes an application environment security structure diagram.
