NIDS Designed Using Two Stages Monitoring
Introduction of high speed network technologies like 3G and 4G and ever increasing network users are giving rise to increased traffic at Network Intrusion Detection System (NIDS). In old NIDS, each captured packet is inspected using database to detect intrusion. But this is not suitable for today`s increased traffic. The new concept of flow inspection, is suffering from scarcity of data. So by combining both inspection methods i.e. flow and packet, two stages monitoring NIDS can be designed which is explained in this paper.
