Abstract: There are provided a method and an apparatus for detecting attacks and automatically generating attack signatures based on signature merging. A method for detecting attacks and automatically generating attack signatures based on signature merging includes detecting a character string matched to at least one previously stored compressed attack signature in an input packet received from a network, determining whether the character string detected in the primary attack detection is matched to at least one previously stored individual attack signature, and, if the detected character string is matched to the at least one previously stored individual attack signature, determining the input packet as an attack packet, and, if the detected character string is not matched, determining the input packet as a new attack signature.

Abstract: Provided herein is a communication method using MIMO (Multiple-Input Multiple-Output) technology for communicating with a terminal included in each of a plurality of base station cells using a communication apparatus, the method including calculating, by the communication apparatus, the number of terminals included inside a base station cell; generating, by the communication apparatus, pilot signals corresponding to the calculated number of terminals; and allocating, by the communication apparatus, the pilot signals to a terminal that may maximize a network capacity based on the generated pilot signals.

Abstract: A network security state visualization scheme is suitable for collecting security events existing in a network, analyzing the security events, categorizing and contracting the analyzed security events into attack state information, and visualizing the attack state information as a three-dimensional (3D) screen to display the visualized information on a display panel. Unlike the related art where security events are expressed from the viewpoint of IPs, this scheme normalizes collected security event information, analyzes the normalized information, categorizes and contracts the analyzed information into the attack state information, extracts visualization target data, visualizes the visualization target data as the 3D screen, and displays the visualized 3D screen on the display panel.
