  • Patent number: 10225269
    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.

  • Patent number: 9130981
    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.

  • Patent number: 7617231
    Abstract: A data hashing method, a data processing method, and a data processing system using a similarity-based hashing (SBH) algorithm in which the same hash value is calculated for the same data and the more similar data, the smaller difference in the generated hash values. The data hashing method includes receiving computerized data, and generating a hash value of the computerized data using the SBH algorithm in which two data are the same if calculated hash values are the same and two data are similar if the difference of calculated hash values is small, wherein a search, comparison, and classification of data may be quickly processed within a time complexity of O(1) or O(n) since the similarity/closeness of data content are quantified by component values for each of the respective corresponding generated hash values.
