We propose to combine and correlate parameters from different layers in order to detect 0\-day attacks and reduce false positives. Moreover, we propose to combine statistical and signal\-based features. The major contribution of this paper are\: novel framework for network security based on the correlation approach as well as new signal based algorithm for intrusion detection using matching pursuit."]
