Technical Application of Network Security

Based on network and management structures of Ticking and Reservation System, this paper analyses potential risks of the system, and presents a three layer protective system which include such advanced technologies as firewall, intrusion detection, security scanning software and internal security strategy. The firewall forms the first gateway of the system, leave most of intrusion failed; the security scanner could pre discover system vulnerabilities, and the intrusion detection could intercept and hold back network intrusion timely; the internal security strategy are applied in operating system, database and the Ticketing System,strengthened former strategy the system used. By making full use of the security technology, an integrated architecture has been established which greatly enhanced the system security.
