- A Grid-Aware Intrusion Detection System
- Existing Intrusion Detection Systems IDS are not designed to deal with any specific types of systems. The purpose of this work is to investigate the possibility of Grid-focused IDS. The main stress is put on feature selection and performance of the system. An existing framework, IDSNet, is used as a...

- A Strategic Review of Existing Mobile Agent-Based Intrusion Detection Systems
- Intrusion Detection Systems IDS is defined as a component that analyses system and user operations in computer and network systems in search of activities considered undesirable from security perspectives. Applying Mobile Agent MA to intrusion detection design is a recent development and it is aimed at effective intrusion detection in...

- The Human Immune System and Network Intrusion Detection
- This paper reviews and assesses the analogy between the human immune system and network intrusion detection systems. The promising results from a growing number of proposed computer immune models for intrusion detection motivate this work. The paper begins by briefly introducing existing Intrusion Detection Systems (IDS's). A set of general...

- Can Intrusion Detection Implementation Be Adapted to End-User Capabilities?
- In an environment where technical solutions for securing networked systems are commonplace, there still exist problems in implementation of such solutions for home and small business users. One component of this protection is the use of intrusion detection systems. Intrusion detection monitors network traffic for suspicious activity, performs access blocking...

- Security for virtual environments from the Catbird Seat
- Alright, the title is a bit of a stretch. What can I say, I love bad puns. I spoke with my friends from Catbird after VMworld and have only now found the time to post something about that conversation. Bad Analyst! Go to your room! ...

- An Analysis of Network Scanning Traffic as It Relates to Scan-Detection in Network Intrusion Detection Systems
- Network Intrusion Detection is, in a modern network, a useful tool to detect a wide variety of malicious traffic. The ever present prevalence of scanning activity on the Internet is fair justification to warrant scan detection as a component of network intrusion detection. Whilst current systems are able to perform...

- A DoS Resilient Flow-Level Intrusion Detection Approach for High-Speed Networks
- Global-scale attacks like viruses and worms are increasing in frequency, severity and sophistication, making it critical to detect outbursts at routers/gateways instead of end hosts. This paper leverages data streaming techniques such as the reversible sketch to obtain HiFIND, a High-speed Flow-level Intrusion Detection system. In contrast to existing intrusion...

- Towards a High-Speed Router-Based Anomaly/Intrusion Detection System
- Traffic anomalies and attacks are commonplace in today's networks, and identifying them rapidly and accurately is critical for large networks. With the rapid growth of network bandwidth and fast emergence of new attacks/worms, existing network Intrusion Detection Systems IDS are insufficient for the following two reasons. First, they are mostly...

- IDGraphs: Intrusion Detection and Analysis Using Histographs
- Traffic anomalies and attacks are commonplace in today's networks and identifying them rapidly and accurately is critical for large network operators. For a statistical Intrusion Detection System IDS, it is crucial to detect at the flow-level for accurate detection and mitigation. However, existing IDS systems offer only limited support for...

- Enriching Intrusion Alerts Through Multi-Host Causality
- Current intrusion detection systems point out suspicious states or events but do not show how the suspicious state or events relate to other states or events in the system. This paper shows how to enrich an IDS alert with information about how those alerts causally lead to or result from...

- Improving the Efficiency and Robustness of Intrusion Detection Systems
- With the increase in the complexity of computer systems, existing security measures are not enough to prevent attacks. Intrusion detection systems have become an integral part of computer security to detect attempted intrusions. Intrusion detection systems need to be fast in order to detect intrusions in real time. Furthermore, intrusion...

- Stop the botnets!
- This is the intention of Paul Barford, a computer scientist at the University of Wisconsin-Madison. He wants to build a new line of defense against malicious traffic which has become today a billion-dollar 'shadow industry.' As one of 'the most menacing aspects of botnets is that they can go largely...

- Improved Detection System of Denial of Service Attack
- 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 nowadays depend on rule-based expert systems where new attacks are not detectable. In this paper, a possible application of Neural Networks is presented as...

- Improving the Performance of Passive Network Monitoring Applications Using Locality Buffering
- This paper presents a novel approach for improving the performance of a large class of CPU and memory intensive passive network monitoring applications, such as intrusion detection systems, traffic characterization applications, and NetFlow export probes. The approach, called locality buffering, reorders the captured packets by clustering packets with the same...

- Implementing Real Time Port Scan Detection for the IP Backbone
- Port scanning is prevalent in today's Internet and often has malicious intent. Although many algorithms have been proposed for different aspects of the scan detection problem, the paper has seen few system discussions in the literature. Furthermore, the few existing systems are designed for enterprise gateway level Intrusion Detection. Targeting...

- Dynamic Protocol Analysis for Network Intrusion Detection Systems
- Many Network Intrusion Detection Systems NIDSs perform application layer protocol analysis. These systems typically infer the protocol from the ports in the TCP or UDP headers. This is not a reliable technique since many protocols do not use fixed ports. On the other hand there exist better methods to identify...
