Web Application Data Protection System

With the deepening of China’s information construction, the number and range of enterpr ise applications continue to expand, and the enterprise application environment becomes mor e and more complex. Because of the period of construction of the enterprises of different bus iness applications and different needs, the data security needs of enterprise-class Web applicat ions will be different. A major feature of these systems is the large amount of data involved in many business-critical information and internal information. They are based on the important data resource to analyse, classify, process,handle, and show the information required for diffe rent users in different ways, so as to meet the daliy business needs of the enterprise.A Web application data protection system is researched and designed in this paper, it can protect the data security of Web applications, prevent Web applications data from being modi fiedand can be effective for data recovery if data is modified. The mainly work in this paper is as the following:(1) A plug-in for Oracle is designed to backup the oracle data to a secure database by writing oracle stored procedure in real-time.(2) For the data backuped, a matchine for data comparing is designed, the data of the original database is compared to the data of the backup database to detect abnormal data.(3)In the process of abnormal data detection, for the conventional direct detection method, a quick and easy detection method is proposed which in the case that it is not need to detect all data when locate the position of the abnormal data and speed up the data detection speed.
