摘要: In this paper we propose a novel approach to identify anomalies in DNS traffic. The traffic time-points data is transformed string, which used by new fast approximate string matching algorithm detect anomalies. Our generic its nature and allows adaptation different types of We evaluate the on large public dataset based 10 days, discovering more than order magnitude attacks comparison auto-regression as baseline. Moreover, additional has been made including other common regressors such Linear Regression, Lasso, Random Forest KNN, all them showing superiority our approach.
