The paper presents two methods for detecting anomalies in data series derived from network traffic. Intrusion
detection systems based on network traffic analysis are able to respond to incidents never seen before by
detecting anomalies in data series extracted from the traffic. Some anomalies manifest themselves as pulses
of various sizes and shapes, superimposed on series corresponding to normal traffic. In order to detect
those impulses we propose two methods based on discrete wavelet transformation. Their effectiveness expressed
in relative thresholds on pulse amplitude for no false negatives and no false positives is then evaluated
against pulse duration and Hurst characteristic of original series. Different base functions are also evaluated
for efficiency in the context of the proposed methods.
