Layered Approach & HMM for Network Based Intrusion Dection
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 5
Abstract
In this, we are using two techniques together as signature based and anomaly based called as Hybrid technique. Anomaly detection, where the strategy is to suspect of what is considered an unusual activity for the subject (users, processes, etc.) and carry on further investigation. This approach is particularly effective against novel (i.e. previously unknown) attacks. Signature based detection systems detects previously known attack in a timely and efficient way. The main issue of this approach is that in order to detect an intrusion this must to be previously detected. This Hybrid technique gives better result than signature based and anomaly based technique. Also we are using here layered approach to get result faster ,because in layered approach we have different four layers as prob,U2R,R2L,DOS and we assigned different features to different layer so that if any layer find attack at that layer that attack will fix ,that attack should not go further. Main aim of this paper is to increase accuracy and efficiency .
