METHOD FOR MONITORING SECURITY OF SYSTEM NETWORK IN REAL-TIME BY IP/PORT UNIT

摘要

PURPOSE: A method for monitoring security of a system network in real-time by an IP(Internet Protocol)/port unit is provided to enable an end host to efficiently monitor/control external accesses by generating a visible/audible alert for a remote connection not verified in a connection list, even if the network is inevitably shared. CONSTITUTION: A connection list table is formed by making the connection list, which is a list of the accessible IPs/ports, for each end host. One service system collects a network connection list of each service system, and judges that the bad network connection list is present by comparing the connection list with the connection list table(S208). If the bad network connection list is present, the bad network connection list is extracted/transmitted to a web server together with the whole network status(S210). The web server displays the whole network status to a monitoring screen and generates the visible/audible alert(S212). If not, the whole network status is transmitted to the web server(S216). The web server displays the whole network status to the monitoring screen(S218).
