Intrusion detection is a problem of great significance to protecting information systems security. An intruder may move between multiple nodes in the network to conceal the origin of attack. Distributed intrusion detection and prevention plays an increasingly important role in securing computer networks. To overcome the limitations of conventional intrusion detection systems, alerts are made in...

The article introduced the importance of intrusion detection, as well as the traditional intrusion detection's type and the limitation. Also, according to the intrusion detection's general process and data mining characteristic, it establishes a data mining-based model of network intrusion detection which is designed for its flaw. As a result, the missing report reduces greatly; the examination...

We have set up a project aiming at developing a dynamical immune intrusion detection system for IPv6 and protecting the next generation Internet from intrusion. We focus on investigating immunological principles in designing a dynamic multi-agent system for intrusion detection in IPv6 environment, instead of attempting to describe all that is intrusion in the network try and describe what is no...

Recent advances in the field of intrusion detection brought new requirements to intrusion prevention and response. Traditionally, the response to an attack is manually triggered by an administrator. However, increased complexity and speed of the attack-spread during recent years show acute necessity for complex dynamic response mechanisms. Although intrusion detection systems are being actively...

Network intrusion detection is the problem of detecting anomalous network connections caused by intrusive activities. Many intrusion detection systems proposed before use both normal and intrusion data to build their classifiers. However, intrusion data are usually scarce and difficult to collect. We propose to solve this problem using a novelty detection approach. In particular, we propose to ...

An Intruder is a hacker or cracker which always tries to get access to secure, system Intrusion occurs when an unauthorized person try to gain access or interrupt the normal operations of an information system. Even when such attacks ar e self-propagating, as in the case o f worms, Trojan Horses and denial-of service attacks, they are almost always initiated by an individual whose purpose is to...

This paper describes an aggregation and correlation algorithm used in the design and implementation of an intrusion-detection console built on top of the Tivoli Enterprise Console (TEC). The aggregation and correlation algorithm aims at acquiring intrusion-detection alerts and relating them together to expose a more condensed view of the security issues raised by intrusion-detection systems.

Agentless network-based threat detection and protection (Network IPS). delivers a consistent management experience across Data Center Security products. configuration monitoring, consolidated event logging, and file and system tamper a combinat...

The Computer Security is a part of Computer Science that addresses all the problems that exists within the computer security domain. Now days, more than ever, the computer viruses, worms, hackers, crackers, electronic eavesdropping and electronic fraud, have become the new problems that the Network Computer Security Science must solve. The Intrusion Detection System has become a needful compone...

With the rapid development of Internet, the network topology structure becomes more and more complex, so that the monitoring of network attack has become quite difficult. The traditional passive defence strategy has been unable to meet the demand of network information security. How to effectively detect and prevent the network intrusion have become an important matter in the field of computer ...
