Design and Realization of Real-time Network Security Monitoring System

This paper brings up a real-time network security monitoring system (RNSMS) and discusses its working pattern, functions and key technology. RNSMS can monitor network activity by real-time. The common network packages(HTTP,FTP,Telnet,POP,SMTP,SSL,UDP) are analyzed and resumed in RNSMS. With OPSEC interface built into RNSMS, RNSMS can cooperate with other network security tools. Tests show that RNSMS is one of efficient network security tools.
