Summary
The wide applications of computer and Internet technology call for a higher demand on the information security. In the process of exploring and designing an information system, security has always been given the first priority, which is critical for the survival of the information system. As the nuclear part of WEB information system, database faces the double threats coming internally and externally. Do such as encryption security process becomes the effective means for data protection. Several popular access technologies are introduced and a primary security model of Web Database is given in the paper.
