Abstract:
A method for displaying event information related to network security is provided to enable a user to visually analyze change of a quantity and connectivity of events of a specific attribute among the events related to the network security, and intuitively recognize a current security situation. The network-related events generated in a managed domain of the network are collected(110). Information including a generation quantity of each application port, the connectivity between a source and destination address, a source and destination address, and an event type to be expressed as a graphic is extracted from the collected event(151,161). The extracted information is displayed as the graphic according to the source and destination address, and interconnectivity among the event types(152,162). An abnormal security state of the managed domain is determined according to a pattern of the displayed graph(170).

Abstract:
PURPOSE: A system and a method for managing charging of an MAIN(Multi-service Access Integrated Network) using web technology are provided to supply a user interface using the web technology, so that users can easily manage operation states and charging. And the system and the method are provided to easily impose charging based on actually transceived data amount. CONSTITUTION: A web client manager(202) supplies a graphic user interface for a system user(201), manages clients, and supplies a connection setup and authentication function and a connection maintenance function. A charging management server(203) classifies the grades of operators to manage the connection of the operator, produces a charging record based on performance information and configuration information., and supplies charging information and performance information according to the request of the system user(201). A CMIP(Common Management Information Protocol) manager server(204) communicates between the charging management server(203) and an agent system(205). The agent system(205) supplies information on network management.

PURPOSE: A context recognition apparatus and method thereof are provided to improve the convenience of a user by automatically recognizing abnormal context by monitoring a micro blog service. CONSTITUTION: A micro blog monitoring unit(100) monitors the writing information of a micro blog and extracts keywords corresponding to establishment titles from the writing information. A web information collecting unit(200) collects web information corresponding to the key words from a web page. A micro blog information collecting unit(300) collects micro blog information corresponding to the writing information including the key words from the micro blog. A context recognition information creation unit(400) creates context recognition information.
Abstract:
PURPOSE: A network monitoring system, security event collecting apparatus, and service error state detecting apparatus are provided to detect the soundness of a network service by using the feature of a transport layer port number. CONSTITUTION: A traffic information creation apparatus(10) creates traffic information. A security event collecting apparatus(100) collects the traffic information. The security event collecting apparatus extracts service information. A service error state detecting apparatus(200) detects the occurrence frequency of a transport layer and the port number of the transport layer from the extracted service information. The service error state detecting apparatus displays a service error state.
Abstract:
PURPOSE: A method for reversely tracking an attacker packet and a system therefore are provided to sense the attacker packet by using a hash function and a bloom filter. CONSTITUTION: A first router(100) receives a hash information list of an attacker packet from a server(300) which reversely track an attack path of the attacker packet in a network. A hash value is extracted by applying a hash function to a reception packet. It is determined whether the information corresponding to the extracted hash value exists in the hash information list. The reception packet is determined to the attacker packet according to the information corresponding to the extracted hash value. The determination result is transmitted to the server.
Abstract:
PURPOSE: A network attach sensing device based on visual data analysis and a method thereof are provided to convert traffic information into an image and sense various attacks on a network using the formed image through a visual data analysis technique. CONSTITUTION: A traffic image generator(100) generates a traffic image through IP additional information. By comparing the traffic image with a previously inputted traffic image, a network attack detector(200) detects a network attack. A network attack analyzer(300) detects network attack information and pattern information of the network attack information. A network attack detection result expression unit(400) expresses the network attack information and the pattern information of the network attack.
