Survey of Current Network Intrusion Detection Techniques

Abstract

The significance of network security has grown enormously and a number of devices have been introduced to perk up the security of a network. NIDS is a retrofit approach for providing a sense of security in existing computers and data networks, while allowing them to operate in their current open mode. The goal of a network intrusion detection system is to identify, preferably in real time, unauthorized use, misuse and abuse of computer systems by insiders as well as from outside perpetrators. This paper presents a nomenclature of intrusion detection systems that is used to do a survey and identify a number of research prototypes. 

Keywords: Security, Intrusion Detection, Misuse and Anomaly Detection, Pattern Matching.
