Intrusion Detection Systems play an invaluable role within organisations by detecting attempted attacks on their IT systems. However, Intrusion Detection Systems are complex to set-up and require large quantities of memory and processing power to effectively analyse the large volumes of network traffic involved. Behavioural analysis plays an important role within Intrusion Detection Systems by ...

As the number of network intrusions emerges, intrusion defense mechanisms are required urgently for providing a highly secure network environment. The intrusion detection system (IDS) is such a system to detect possible intrusions of networks, and to minimize the response time between intrusion detection and defense reaction as much as possible. In this paper, we propose a network-based intrusi...

The paper presents a preliminary description of an intrusion taxonomy to aid the development of a generic intrusion specification and response platform. Existing intrusion taxonomies are assessed in order to derive a suitable classification of incidents that would be both detectable and addressable by an automated intrusion detection system. The issue of automated responses to intrusions is con...

Network-based intrusion has become a serious threat to today’s highly networked information systems, existing intrusion defense approaches such as intrusion prevention, detection, tolerance and response are “passive” in response to network-based intrusions in that their countermeasures are limited to being local to the intrusion target and there is no automated, network-wide counteraction again...

Nowadays the organizations are facing the number of threats every day in the form of viruses and attack etc. Since many different mechanisms were preferred by organizations in the form of intrusion detection and prevention system to protect its organizations from these kinds of attacks. Intrusion Detection System (IDS) is considered as a system integrated with intelligent subsystems. In this pa...

Currently available products only provide some support in terms of Intrusion Prevention and Intrusion Detection, but they very much lack Intrusion Diagnosis features. We discuss the limitations of current Intrusion Detection System (IDS) technology, and propose a novel approach which we call Intrusion Detection & Diagnosis System (IDS) technology to overcome such limitations. The basic idea is ...

Intrusion detection is an important security tool. It has the possibility to provide valuable information about the current status of security. However, as enterprises deploy multiple intrusion detection sensors at key points in their networks, the issue of correlating messages from these sensors becomes increasingly important. A correlation capability reduces alert volume, and potentially impr...

Problem statement: Wireless LAN IEEE 802.11 protocols are growing rapidly and security has always been a concern with the security of wired network. Wireless networks encountered threats from unauthorized access to network resources, installation of access points and illegal sniffing (refer as classical intrusion threats). In its current hybrid wired and wireless network attacks on the generall...

Ad hoc networks have received great attention in recent years, mainly due to their important advantages and their growing demand. Nevertheless, ad hoc networks present many inherent vulnerabilities and demand efficient security mechanisms in order to be safeguarded. An efficient intrusion detection approach combined with an authenticated intrusion response can act as an effective line of defens...

The goal of Distributed Intrusion Detection System is to analyze events on the network and identify attacks. The increasing number of network security related incidents makes it necessary for organizations to actively protect their sensitive data with the installation of intrusion detection systems (IDS). There is a difficulty to find intrusion in an distributed network segment from inside as w...
