Evaluation Model for DoS Attack Effect in Softswitch Network

By analyzing features of DoS attacks in soft switch network, in this paper we propose a set of attack effect evaluation indices, which take both users and systems into consideration. A model combining SPA and fuzzy comprehensive judgment is designed to evaluate DoS attack effect. This model performs well in evaluating attack without deterministic evaluation indices, and it can not only provide evaluation for individual attack, but also rank the effect from a sequence of attacks. Our experiment demonstrates that the proposed evaluation indices and model provide reasonable evaluation results for DoS attacks in soft switch network.
