Performance improvement of deep packet inspection for Intrusion Detection

The development in anomaly and misuse detection in this decade is crucial as web services grow vast. Managing secure network is a challenge today. The objectives vary according to the infrastructure management and security policy. There are various ways to check stateful packet inspection and Deep Packet inspection (DPI). Identify payload traffic using DPI, Network security, Privacy and QoS. The functions of DPI are protocol detection, anti-virus, anti-malware and Intrusion Detection System (IDS). The detection engine may support by a signatures or heuristics. Most of the algorithms do training and testing, it takes approximately double time. The paper suggests a new model to improve performance of Intrusion detection system by using in/out based attributes of records. It takes a comparative less time and good accuracy than the existing classifiers.
