Card System Database Security And Safety Enhancement Technology Research

Along with digitized campus's starting with application thorough, a present's campus all-in-one-card system scale is keeping developed, increasingly complex functions, in the practical application of the system, there are many problems, particularly in security issues. All-in-one-card system built on the basis of the campus network system, the system involves some sensitive data, many business-critical systems running on the database platform. If the database can not guarantee security, the application system will be illegal to access or damage. How to effectively prevent the possible application of the various attacks, destruction and fraud and make the campus card database system could be operated safely in an open network environment, to achieve a comprehensive and effective database security control program has become the most important to the campus card system.The issue stems from Zibo Vocational College Campus all-in-one-card System technological transformation project. The aim of the investigation is to introduce new database security technology on the basis of technical analysis of the original Card System database security, to further improve security of the campus card database system and to promote the application of the campus card system to develop in depth.The thesis firstly analyzes the safety and reliability of the system structure and its components in-depth according to the application status of the security technology of database and all-in-one-card system at home and abroad, and the characteristics of all-in-one-card System and security requirements of its database. Focus on the existing security technologies of the card system database, mainly based on the Oracle database system, for the authentication of database user password. For the role safe access control mechanism, the fine grain audit monitoring mechanism, the data backup with restored and so on to give the technology to realize, and through the memory process, the function and the routine package method improved to the existing database system safety function. Finally designs a set of security enhancement programme of Card System database which based on the intrusion detection technologies. It unifies the redundancy and the multiple technologies, intrusion detection and effective integration of technology's invasion of tolerance, constructed outer defense, the Middle intrusion detection; within tolerate the invasion of enhancing the security of the database system model.In the end,the article carried on the summary to the whole system,and pointed out the shortage and the future work.
