A system for an engine for forecasting cyber threats and a method enabling the forecast of a low-level cyber threat and the forecast of a high-level cyber threat using the low-level cyber threat in a hierarchical structure of cyber threats are provided. The system includes a forecast information database which stores forecast information including cyber threat forecast items, a forecast schedule related to the items, forecast simulation information, forecast item hierarchical structure information, time series data on cyber threats, and sample data on cyber threats; a forecast engine core subsystem which forecasts the levels of threats for the cyber threat forecast items having a hierarchical structure using the forecast information stored in the forecast information database; and a forecast engine control interface which receives control commands for the forecast engine core subsystem from a user or external system, and delivers the received control commands to the forecast engine core subsystem.

An apparatus and method for detecting anomalous traffic are provided. More particularly, an apparatus and method for detecting anomalous traffic based on entropy of network traffic are provided. The apparatus of detecting anomalous traffic includes: an entropy extraction module for extracting entropy from network traffic; a visualization module for generating an entropy graph based on the entropy; a graph model experience module for updating a graph model for each network attack based on the entropy graph; and an anomalous traffic detection module for detecting anomalous traffic based on the entropy graph and the graph model for each network attack and outputting the detection results to a user. In the apparatus and method, anomalous traffic is detected based on network entropy rather than simple statistics based on the amount of traffic, so that a false alarm rate of the apparatus for detecting anomalous traffic can be reduced.

Provided are a system and method for predicting a cyber threat. The system and method collect various variables and synthetically predict the frequency, dangerousness, possibility, and time of the occurrence of a cyber threat including hacking, a worm/virus, a Denial of Service (DoS) attack, illegal system access, a malicious code, a social engineering attack, system/data falsification, cyber terror/war, weakness exploitation, etc., using a time-series analysis method and a Delphi method, and inform a user in advance of the prediction result, thereby enabling the user to prepare against the cyber threat.

In order to enhance image quality, a terminal, when displaying an image on a QVGA display with a resolution greater than the image itself, renders one of every 5 to 7 pixel rows and one of every 5 to 7 pixel columns semi-transparent. The semi-transparent pixel rows and columns are displayed with opacity of between 10% and 40% of the original pixels. For example, an image having a resolution of 176×144 pixels is displayed at 320×240 pixels on a QVGA display will have one of every 5 to 7 pixel rows and columns semi-transparent.
摘要:
The present invention relates to a mixed strain culture for the disposal of food waste, and more particularly, to a mixed strain culture for the disposal of food waste which has high degradation activity on cellulose, amylose, protein, and fat at a wide range of temperatures, pH levels, and salinities, and which can degrade food waste having a high moisture content and therefore can degrade food waste in an efficient manner. The present invention also relates to a food waste disposal method using the mixed strain culture.
摘要:
A mobile communication terminal having a multiparty video call function and a method for converting a mode of a multiparty video call are disclosed. The terminal includes an input unit that receives a command for selecting one of phone call modes and a controller that displays a menu for selecting a phone call mode on the display, when a request for a video call or video chatting with the third terminal is wirelessly transmitted or received while the mobile communication terminal is performing video call communication or video chatting, and maintains an established call mode or converts the established call mode to a different phone call mode according to a phone call mode selected through the input unit to perform multiparty video call communication.
摘要:
A method for controlling a mobile terminal includes setting a variable menu icon to represent different functions for first and second operating modes, displaying a plurality of menu icons including the variable menu icon during the first operating mode, and switching the variable menu icon from a function different from a previous function of the variable menu icon during the first operating mode when the mobile terminal changes from the first operating mode to the second operating mode. The other menu icons may be controlled to maintain previous functions that they assumed during the first operating mode after the function of the variable menu icon is switched.
