Abstract

In this paper, we propose the algorithms of processing the uncertainty data using data fusion for the next generation intrusion detection. In the next generation intrusion detection, a lot of data are collected by many of network sensors to discover knowledge from generating information in cyber space. It is necessary the data fusion process to extract knowledge from collected sensors data. In this paper, we have proposed method to represent the uncertainty data, by classifying where is a confidence interval in interval of uncertainty data through feature analysis of different data using inference method with Dempster-Shafer Evidence Theory. In this paper, we have implemented a detection experiment that is classified by the confidence interval using IRIS plant Data Set for anomaly detection of uncertainty data. As a result, we found that it is possible to classify data by confidence interval.

본 논문은 차세대 침입탐지 시스템을 위해서 데이터 융합에서의 불확실한 데이터 처리의 알고리즘을 제안한다. 차세대 침입탐지는 사이버 공간에서 생성되어지는 정보를 지식으로 만들어내기 위해 수많은 네트워크 센서로부터의 데이터가 수집되어진다. 수집된 센서 정보를 지식의 수준으로 이끌어내기 위해서 데이터 융합의 과정이 필요하다. 이를 위해 본 논문에서는 Demster-Shafer 증거이론 추론적 기법을 통하여 서로 다른 데이터들의 특징을 분석하여 불확실한 데이터가 어느 구간에서 신뢰구간을 갖는지를 분류하여, 불확실한 데이터에 대한 표현을 이루어낸다. 본 실험내용에서는 이러한 불확실성 데이터에 대한 이상탐지를 위해 iris plant 데이터세트를 이용한 신뢰구간에 따른 분류를 실행하였다. 이에 대해 각 신뢰구간을 통해서 데이터 분류가 가능하다는 것을 검증하였다.
