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...

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 ...

To improve network security different steps has been taken as size and importance of the network has increases day by day. Then chances of a network attacks increases Network is mainly attacked by some intrusions that are identified by network intrusion detection system. These intrusions are mainly present in data packets and each packet has to scan for its detection. This paper works to develo...

IPv6 has enough IP addresses to solve the problem of lack of IP address space. However, there are many security problems to be concerned. The detection ability of current intrusion detection system is poor when given less priori knowledge. In this paper, we analyze the Least Squares Support Vector Machine (LS-SVM) algorithm and the working process of snort intrusion detection system. And then w...

Intrusion Detection Systems (IDSs) detects the network factor for traditional SNORT (Network Based Intrusion. Detection Using Genetic Algorithms for intrusion detection has proven to be an implementation method. Section IV. Designing of On Line Intrusion Detection System Using Rough Set Theory and Q Evaluation of Rough Set Theory Based Network Traffic Data Classifier Using Traffic Data Classifi...

Introduction Fish in culture are susceptible to a wide range of bacterial, viral, parasitic and fungal infections (Austin & Austin, 1993) and losses through disease currently make a significant impact on the quality and volume of fish produced in Europe. Disease control is therefore a vital component of successful aquaculture. Rapid detection and identification of pathogens is necessary for eff...

Software is increasingly being constructed using the component-based paradigm in which software systems are assembled using components from multiple sources. Moreover, these systems are increasingly dynamic; a core set of components is assembled and then new functionality is provided as needed by dynamically inserting additional components. A newer trend closely associated with the use of compo...

Industrial control system communication networks are vulnerable to reconnaissance, response injection, command injection, and denial of service attacks. Such attacks can lead to an inability to monitor and control industrial control systems and can ultimately lead to system failure. This can result in financial loss for control system operators and economic and safety issues for the citizens wh...

Intrusion detection technology is a research hotspot in the field of information security. This study introduces the types of traditional intrusion detection and data mining technology; Aiming at the defects and limitations of current intrusion detection system, the study has fused the data mining technology into intrusion detection model, and has designed and implemented the intrusion detectio...
