ALERT TRAFFIC CONTROL APPROACH FOR SECURITY MANAGEMENT SYSTEM IN WIDE AREA NETWORK

摘要

PURPOSE: A system and a method for controlling alert traffic in a network are provided to enable a central management system to effectively manage alert traffic while effectively transmitting main alert information in close cooperation with lower security systems which transmit the alert traffic. CONSTITUTION: Plural lower security systems(200) control an amount of alert information to be transmitted, based on an alert information transmission control policy, determine alert priorities, and transmit the alert information in the order of the highest importance. A central management system(100) receives the transmitted alert information while periodically monitoring an amount of alert traffic transmitted from the lower security systems(200), and sends the alert information transmission control policy which considers a processing capacity and availability of the lower security systems(200) to the lower security systems(200).
