Intrusion detection and response has traditionally been performed at the network and host levels That is intrusion monitors will typically analyze network packet logs or host machine audit logs for signs of intrusion activity More often than not commercial o the shelf COTS intrusion detection tools use ngerprints of known intrusions to detect their presence in these audit trails Both these appr...

This Paper titled “Novel Approach for Intrusion Detection System” is an intrusion detection system (IDS) proposed by analyzing the principle of the intrusion detection system based on host and network. Basically this paper is to develop host based cum network based intrusion detection system for Microsoft Windows XP environment. Proposed concept that had used in this was applying intrusion dete...

Internet provides huge information and value to the users but at the same time access to the internet is prone to increasing number of attacks. Tracing the source of the attacking packet is very difficult because of stateless and destination based routing infrastructure of Internet. If the attacks are detected successfully, then preventive measures for attacks can be taken. Host based and netwo...

This paper proposes an intrusion detection and prediction system based on uncertain and imprecise inference networks and its implementation. Giving a historic of sessions, it is about proposing a method of supervised learning doubled of a classifier permitting to extract the necessary knowledge in order to identify the presence or not of an intrusion in a session and in the positive case to rec...

A intrusion provides an unauthorized access, damage or disruption of the network. The process can understand the characteristics and nature of an intruder. The paper presents the taxonomy consists of the specification of an intruder. Taxonomy provides the classification of intruder and provides mechanism for intruder detection. We found the algorithm for developing an intruder which can be atta...

Host intrusion detection systems (HIDSs) are important tools used to provide security to computer systems. Many HIDSs exist and security practitioners need a way to determine the optimal security solution for their environment. Current evaluations of HIDSs focus on detection accuracy and typically do not account for the possibility that an adversary may subvert the HIDS and modify the outcome. ...

This paper explores the application of probabilistic information retrieval theories to the field of log analysis and host-based intrusion detection. Strong similarities exist between intrusion detection and information retrieval. Using information retrieval techniques may yield significant improvements to the performance of intrusion detection systems. This paper provides a brief review of curr...

Intrusion Detection System (IDS) due to novel attack method or upgraded. Because many current IDSs are constructing by point instruction of professional knowledge, changes to IDSs are costly and slow. Intrusion detection techniques can be categorize into irregularity detection and mistreat detection. Anomaly detection systems, for example, IDES Intrusion detection systems (IDS) process large am...

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...
