Free registration required

Executive Summary

Through deeply analyzing on the principle, mode, character of SIP DoS and the flooding attacks faced by SIP network, the prevention model to combine a dynamic threshold adjustment with real-time dynamic prevention for SIP flooding attacks was proposed. This model included logically chi-square traffic judgement model, cumulative statistics model and IP prevention model, among which chi-square traffic judgement module and cumulative statistics module were combined to dynamically adjust the threshold and detect SIP flooding attacks, and IP defense model dynamic prevented IP-based SIP flooding attacks.
