Abstract:
This paper describes the use of the nonparametric Cumulative Sums (CUSUM) algorithm for detecting flooding attacks against SIP infrastructures. The efficiency of this detection mechanism is validated using trace-driven simulations. Using an appropriate function, the nonparametric CUSUM equations are transformed to some parametric CUSUM equations for a Poisson model. This allowed us to verify the accuracy of the results provided by the experiments.
