摘要:
The nail art device having a control unit; a holder; a display panel that displays a predetermined selected pattern through the control of the control unit; and a UV irradiation unit that irradiates the display panel with UV rays is provided. When a finger, to the nail of which polish having a UV-reactive component has been applied, is placed in the holder, the polish applied to the nail reacts with the UV rays which are transmitted through the display panel where the selected pattern is displayed to form a nail pattern.

Disclosed are a system for sharing information between heterogeneous service providers, including: a first service provider configured to generate first situation information based on an abnormal situation of a system; a second service provider configured to receive the first situation information from the first service provider, generate second situation information corresponding to the received first situation information; and the TTP configured to receive the first situation information from the first service provider, receive the second situation information from the second service provider, generate correspondence information based on the received information, and share the generated correspondence information.
摘要:
An apparatus and method for extracting signature candidates and optimizing a corresponding signature are provided. The apparatus includes a packet separator, a header parser, a traffic information generator, a substring extractor, and a signature candidate extractor. The packet separator separates a packet into a header and a payload. The header information parser parses the header information, and the traffic information generator generates traffic information. The substring extractor measures a frequency of appearing of a substring with a predetermined length in the separated payload for a constant observation period, and extracts a substring having a frequency higher than a predetermined setup value by updating the measured frequency information to a substring frequency table. The signature candidate extractor generates a signature by collecting the extracted substring information and the generated traffic information, updates a signature frequency table, and extracts a signature candidate with reference to information of the signature frequency table.

Provided is a method and apparatus for generating a network attack signature capable of generating a signature having a high reliability while minimizing a whitelist used to prevent false positive. An application header and application data are separated from each other to measure byte distributions of the application header and the application data from an input packet. When an attack signature is generated by analyzing the measured byte distributions, a substring of the application data is used to generate the attack signature, and a substring of the application header is used as supporting information on the signature.
