However, if a computer is blocked by the flow control mechanism, it may continue access the network resource without restriction through SOCKS server technology. In most campus network environment, firewalls may not be used or only is used in their primitive mode because of the high bandwidth and academic research requirements. Furthermore, when a computer of the network uses public IP rather than private IP, an unauthorized SOCKS server in the campus network may thread the safety of the campus network. If the SOCKS server in the campus network is taken advantage of by external users because of being implanted or other reasons, the threat is even worse than the former.
Therefore, to block these unauthorized servers become an urgent event to the campus network administrators. In this research we study the behavior of SOCKS server, and design an automatic tracking, blocking and prevention model. A testing environment is set up. When an unauthorized SOCKS server in the campus network is used to access network resources by the external client, the automatically tracking and blocking mechanism are activated to block the unauthorized SOCKS server.
