An Enhancement of Network Anomaly Detection Method Using Occurence Probability Matrices of Correlation Coefficients

Abstract (in Japanese) (See Japanese page) 
(in English) Recently, a network anomaly detection method focusing
correlation coefficients between traffic features has been proposed.
This conventional method uses occurrence probability matrices of
correlation coefficients for detecting anomalies and identifying
traffic features.
However, the conventional method fails to detect anomalous events
in the case that the variation of correlation coefficient value
is large in normal conditions.
For detecting such events, we propose the modification of the
conventional method to evaluate the anomalous increase of correlation
coefficients value.
Through experiments using real traffic data, we show
the effectiveness of the proposed method.
