Multiple time series fisher periodicity test for the detection of the distributed new shrew attacks
Paul Cotae, Myong H. Kang, Alexander Velazquez · 2016
We focus on the detection of Low Rate Denial of Service Attacks (LR DoS) based on their spectral properties. Fisher g-statistics test for one time series was used to detect low frequency periodic bursts of Shrew and New Shrew attacks. The main contribution of this paper is the extension of Fisher g-statistic test to multiple time series. We developed an algorithm based on Fisher G-statistics test that identifies all attackers of the Distributed New Shrew attacks. Numerical examples of Fisher g-statistics test for one time series and of Fisher G-statistics test for multiple time series are provided. We have simulated the Shrew, New Shrew and Distributed New Shrew attacks with an NS-3 simulator.
