Mobile ad-hoc networks are temporary wireless networks. Network resources are abnormally consumed by intruders. Anomaly and signature based techniques are used for intrusion detection. Classification techniques are used in anomaly based techniques. Intrusion detection techniques are used for the network attack detection process. Two types of intrusion detection systems are available. They are a...

The Intrusion Detection System (IDS) has become a critical component of wireless sensor networks security strategy. In this paper we have made an effort to document related issues and challenges of intrusion detection system for wireless sensor network and proposed a novel secure strategy for their implementation that can detect possible intrusion in the network, alerting user after intrusion h...

The computer network security plays an important role in modern computer systems with the widespread use of network. Intrusion diction technology has become very important in the area of network security research. Performance of common intrusion detection system is low and error detection rate is high. In order to overcome the current high rate of false positives, low detection rate and other d...

In today’s world, almost everybody is affluent with computers and network based technology is growing by leaps and bounds. So, network security has become very important, rather an inevitable part of computer system. An Intrusion Detection System (IDS) is designed to detect system attacks and classify system activities into normal and abnormal form. Machine learning techniques have been applied...

In the current internet world where peoples are connected through communication channel and most of their data is hosted on the internet connected resources. Therefore the security is the major concern of this internet community to protect the resources and to protect the data hosted on these networks. In current trends, most of the end user are relying on the end security products such as Anti...

In this paper we propose a distributed intrusion detection system for ad hoc wireless networks based on mobile agent technology. Wireless networks are particularly vulnerable to intrusion, as they operate in open medium, and use cooperative strategies for network communications. By efficiently merging audit data from multiple network sensors, we analyze the entire ad hoc wireless network for in...

Today network security has become an everyday problem with virtually all computers connected to the Internet. Intrusion detection serves the important function of identifying malicious activities and determining their nature, origin, and seriousness. Inspired by the many excellent characteristics of biological immune System (BIS), the network intrusion detection system (NIDS) which based on art...

Intrusion Detection systems are increasingly a key part of system defence. Various approaches to Intrusion Detection are currently being used but false alarm rate is higher in those approaches. Network Intrusion Detection involves differentiating the attacks like DOS, U2L, R2L and Probe from the Normal user on the internet. Due to the variety of network behaviors and the rapid development of at...

In the information era, as computer networks and related applications become more and more popular, security problems are more and more serious in global information infrastructure. It was reported that in the past two years, large amounts of network attacks and computer viruses caused great damages to global economy and the potential threats to the global information infrastructure have increa...

Network Security has become the key foundation with the tremendous increase in usage of network-based services and information sharing on networks. Intrusion poses a serious risk to the network security and compromise integrity, confidentiality & availability of the computer and network resources. Human classification of network audit data is expensive, time consuming and a tedious job. Intrusi...
