With the ever increased use of computers for critical systems, computer security— the protection of data and computer systems from intentional, malicious intervention—is attracting increasing attention. Many methods of defence already exist, of which one is the strong perimeter defence. This thesis is concerned with one such method of defence, the automated computer security intrusion detection...

The study examined the detection of attacks against computer networks, which is becoming a harder problem to solve in the field of Network security. A problem with current intrusion detection systems is that they have many false positive and false negative events. Most of the existing Intrusion detection systems implemented depend on rule-based expert systems where new attacks are not detectabl...

–Nowadays, as information systems are more open to the Internet, the importance of secure networks is tremendously increased. New intelligent Intrusion Detection Systems (IDSs) which are based on sophisticated algorithms rather than current signature-base detections are in demand. There is often the need to update an installed Intrusion Detection System (IDS) due to new attack methods or upgrad...

Intrusion Detection System (IDS) which is increasing the key element of system security is used to identify the malicious activities in a computer system there are different approaches being employed in intrusion detection systems. The prediction process may produce false alarms in many anomaly based intrusion detection systems. With the concept of fuzzy logic, the false alarm rate in establish...

The goal of the article is to presents intrusion detections systems and design architecture of intrusion detection based on neural network self organizing map. In the report is described base problematic of neural network and intrusion detection system. The article further deals with specific design of intrusion detection architecture based on user anomaly behavior. A core of the designed archi...

In the real time Intrusion Detection system, the main confront is to detect the Anomaly Intrusion Detection system Model with ADWIN change Detector. intrusion detection system, that utilizes machine learning techniques such as single classifier and hybrid build the model was decreased and the detection. Intrusion Detection System (IDS) to detect and prevent cybercrimes to protect these The prop...

Intrusion Detection and Prevention System is a must for mobile ad networks as the security mechanisms like encryption, authentication and firewall systems are not able to completely secure the nodes and their communication. In this paper, we aim to study the various intrusion detection and prevention systems that were proposed for Mobile Adhoc Networks (MANETs) and compare the recent techniques...

Intrusion detection plays one of the key roles in computer system security techniques. This paper is dedicated to this topic. It describes major approaches to intrusion detection and focuses on methods used by intrusion detection systems. We do not describe in this paper details of existing intrusion detection system. Instead, we concentrate on underlying principles and methods. This paper can ...
