The Research And Development On Security Scheme Of College Educational Information System

With the rapid development of the internet and the computer technology, today’s society has entered into an internet era; information network has become a powerful driving force for social and economic development. Campus in our country as higher education base, it is not only in the social environment, but also is the main factors of social progress. The modern、digital and high efficiency educational information system construction is an important link of the high level university construction. Educational network management system is a management system.At first, this paper analyzes the risk of the security demand of college teaching management information system on the base of previous studies, and then for the characteristics of university educational information system:it first applies the high security authentication system which based on the PKI/CA to the university educational network management system; then it applies the high reliability data safety isolation technology to the data security transmission of educational information system; finally, it applies the state inspection firewall to boundary protection management information system, to ensure the safety of the educational information system from multiple directions. The main research work is as follows:1) A full range of prevention and control of security system.Based on the present security problem of university educational network management system, it puts forward the safety control system to ensure the educational network management system to operate normally; it also analyzes the structure and content of the security system.2) The identity authentication technology with high reliability.It applies the PKI/CA technology to identity authentication system. Based on the CA certificate, it completes the identity authentication process under the PKI environment to realize the user’s authentication safety.3) To ensure the safety of isolation and transmission of the information data system.Because the existence of a large number of sensitive security information for educational departments, there is objective demand to prevent disclosure of confidential information, this paper uses the high safety data isolation technology to realize data transmission and exchange between the different levels of security network.4) The high security boundary protection.Ensure the boundary protection safety information system of intranet and internet by using advanced inspection packet filter firewall technology.Finally, this paper gives the summarization and prospection to the security of the educational information system.
