In this paper, a novel method of recognizing and predicting multi-step attacks is proposed. It calculatesattack conversion frequencies, and then mines the multi-step attack sequences. On this basis, it matches the new alert sequences dynamically, recognizes the multi-step attacks and predicts the next attack step. The result of experiment shows that the proposed method is effective and accurate. %K Network security %K multi-step attack %K alert correlation %K attack conversion frequencies %U http://www.mecs-press.org/ijwmt/ijwmt-v2-n2/v2n2-4.html
