Abstract:
PURPOSE: An apparatus and a method for supplying a user profile based on security service are provided to generate a user profile which shows a behavior pattern of a user and to recognize a behavior of the user threatening the security. CONSTITUTION: An event collector(110) collects event data and user data generated from an IT(Information Technology) device and a logical/physical security device. A profile generator(140) generates user profile information by using the user data and the event data. A user analyzer(150) analyzes the event data and calculates the security threat of the user.

Abstract:
PURPOSE: A network attack location searching method and system using a spy-bot agent is provided to detect and trace the attacker over wide place by obtaining the packet information of the packet which accesses the each host from a remote place. CONSTITUTION: A back tracking server(300) detects one or more dangerous host through host scanning. A spy-bot management server(200) transmits the spy-bot agents(100) to the detected dangerous host. The spy-bot management server obtains packet information of the packet which accesses the each dangerous host through spy-bot agents. The back tracking server references the obtained packet information and reversely traces the starting point of the hacking code.
Abstract:
An apparatus and a method for displaying a network state are provided to determine an abnormal state which deteriorates the performance of a network by using information about distinct dispersion, entropy, and clustering as a result of a combination of important properties in a traffic event, and detect a harmful traffic or an abnormal traffic. A method for displaying a network state comprises the following steps of: grouping traffics according to a protocol(S100); selecting and combining three of a resource address, a resource port, a destination address, and a destination port, and calculating distinct dispersion and entropy for a remaining element(S200); displaying the calculated distinct dispersion and entropy on a security radar that an angle of a circle is divided into N and a radius of the circle is divided into M(S300); and detecting the abnormality of a network by referring to a displayed radar state and detecting and reporting a harmful traffic or an abnormal traffic which causes an abnormal state(S400).
