Current IDSs usually have several shortcomings. First, the speed and sensitivity of detection are not so ideal. Secondly, the response system lacks the ability to correct errors. Thirdly, the cost of intrusion detection is not considered, that is, the response policy is static. This paper applies fuzzy default theory to transform reasoning and response engine of IDS, based on the proving of IDS...

An intrusion detection system (IDS) is a device or application that monitors all Host based IDS refers to intrusion detection that takes place on a single host. Host-based Intrusion Detection System (HIDS) and File Integrity Monitoring (FIM) policy violations, vulnerable software, or suspicious communications. An IDS can be a piece of installed software or a physical appliance Host intrusion de...

In current scenario most of the intrusion detection systems (IDS) use one of the two detection methods, misused detection or Anomaly detection?both of them have their own limitations. Technology has developed the technique that combines misuse detection system with anomaly detection system (ADS) or network intrusion detection system and host-based intrusion detection system is known as hybrid i...

This paper details the design and implementation of a host-based intrusion detection system (Hewlett-Packard’s Praesidium IDS/9000) and a specialized kernel data source which supplies customized data to the IDS. Instead of the common attack-signature matching used in most other intrusion detection systems, IDS/9000 performs real-time monitoring of the system looking for misuse actions that are ...

Network security is one of the most important non-functional requirements in a system. Over the years, many software solutions have been developed to enhance network security. Intrusion Detection System (IDS) we have provided an overview of different types of intrusion Detection Systems, the advantages and disadvantages of the same. The need for IDS in a system environment and the generic block...

A hybrid approach for intrusion detection in computer networks is presented in this paper. The proposed approach combines an evolutionary-based fuzzy system with an Ant Colony Optimization procedure to generate high-quality fuzzy-classification rules. We applied our hybrid learning approach to network security and validated it using the DARPA KDD-Cup99 benchmark data set. The results indicate t...

session initiation protocol (sip) is the main signaling protocol of next generation networks (ngn). sip based applications are usually deployed over the internet, for which their text-based nature and internal stateful operation make them vulnerable to different types of attacks. the real‑time functionality of sip based applications make their related security systems more complex. on the other...

The Mobile Agent Intrusion Detection System (MAIDS) is an agent based distributed Intrusion Detection System (IDS). A disciplined requirement engineering process is developed to build MAIDS. The starting point is a high level description of intrusions expressed as Software Fault Trees (SFTs). Then the SFTs are translated to Colored Petri Nets (CPNs) that specify the IDS design. Subsequently, th...

Intrusion detection is the act of detecting unwanted traffic on a network or a device. A intrusion detection system (IDS) provides a layer of defense which monitors network traffic for predefined suspicious activity or patterns, and alert system administrators when potential hostile traffic is detected. Intrusion detection faces a number of challenges; an intrusion detection system must reliabl...

Intrusion Detection System is significant in network security. It detects and identifies intrusion behavior or intrusion attempts in a computer system by monitoring and analyzing the network packets in real time. In the recent year, intelligent algorithms applied in the intrusion detection system (IDS) have been an increasing concern with the rapid growth of the network security. IDS data deals...
