Description: We consider systems of intrusion detection and prevention in modern telecommunications systems and networks. We study methods for monitoring events consisting in the analysis of network activity of individual services and information services of telecommunication systems and networks. Encouraged to use mathematical apparatus ANOVA processing simulation results telecommunication systems and study the statistical properties of network traffic when determining the significance of differences or matching characteristics. The proposed approach is to use a statistical test of Fisher , based on an assessment of the relationship sample variances , which allows a given level of significance test the hypothesis of homogeneity of the statistical properties of network traffic with respect to dispersion ( variance). The obtained experimental results should be used for improving the mechanisms for monitoring the network activity of individual services and information services, including for intrusion detection and prevention in the telecommunication systems and networks.
Keywords: telecommunication systems and networks, system intrusion detection and prevention, analysis of variance
