Database And Network Security Research Of VPDN Computer Manager Billing System

Virtual Private Network (VPN) provides the enterprise an approach to access the information on VPN traversing Internet, which could reduce costs for the enterprise and provide Value-added services for dealer of telecom. Virtual Private Dial Network (VPDN) is used by enterprise and dial users. VPN/VPDN computer management system is an integrated system which manages and maintains VPDN users and authenticates and billing. Research on VPN/VDPN charge management software has so important academic value and practical foreground that it has become the focus of the present information technology field. So the reliability and security of the system is confronted with challenges.This paper makes a disquisition on security of both the system database and the network server. Completely considered the security and stability of the system and illustrating with practical application, this paper represents the design method of the system and the implementation mechanism of the VPDN authentication server and the database server.
