A Log Analysis Based Intrusion Detection System for the Creation of a Specification Based Intrusion Prevention System
White Paper This paper proposes a novel Intrusion Prevention System (IPS) which would base its knowledge and operation on a higher level of abstraction than the processing of the contents of the network packets audit data themselves which is the source of... [10 Jul 2008]
Data Collection Mechanisms for Intrusion Detection Systems
White Paper It is claimed that it is best for an intrusion detection system to be able to collect its data by looking directly at the operations of the host, instead of indirectly through audit trails or network packets. [10 Jul 2008]
A Load Balancing Algorithm for High Speed Intrusion Detection
White Paper Based on the contents of fields in IP packet header and some simple operations, this algorithm can keep the relativities among packets in a high bandwidth network environment while distributing workload to different processing node. [10 Jul 2008]
Characterizing the Performance of Network Intrusion Detection Sensors
White Paper However, even a high-quality NIDS algorithm is not effective if its processing cost is too high, since the resulting loss of packets increases the probability that an attack is not detected. Network Intrusion Detection Systems (NIDS) are becoming... [10 Jul 2008]
A Java Based Network Intrusion Detection System (IDS)
White Paper The packets in the network are captured online i.e.as they come on the interface of the network. In this research project designs and builds an Intrusion Detection System (IDS) that implements pre-defined algorithms for identifying the attacks over... [09 Jul 2008]
A Feature Classification Scheme for Network Intrusion Detection
White Paper This paper presents a feature classification schema for network intrusion detection intended to provide a better understanding regarding the features that can be extracted from network packets. One of the most important phases of the IDS/IPS... [09 Jul 2008]
Enhancing Network Intrusion Detection With Integrated Sampling and Filtering
White Paper The structure of many standalone Network Intrusion Detection Systems (NIDSs) centers around a chain of analysis that begins with packets captured by a packet filter, where the filter describes the protocols (TCP/UDP port numbers) and sometimes... [08 Jul 2008]
Comparison of Two Sampling-Based Data Collection Mechanisms for Intrusion Detection System
White Paper Simple random sampling and Stratified random sampling techniques of statistics are introduced to the procedure of data collection for IDS, and formulas used to calculate the sample size of packets based on these sampling techniques are presented. [06 Jul 2008]
Combining Evasion Techniques to Avoid Network Intrusion Detection Systems
White Paper The evasion techniques used were segmentation of the attack into smaller packets, overlapping data in the packets, and the presence of "Presequence chaff". Three different Network Intrusion Detection System (NIDS) evasion techniques were combined... [03 Jul 2008]
An Intrusion Detection System With Active Response Generation
White Paper The solution is capable of searching for intrusion signatures inside the packets that come from multiple network interfaces simultaneously and capable of analyzing and filtering packets on any or all directions of traffic. [02 Jul 2008]
New Trend of Intrusion Detection System for High-Speed Networks
White Paper To guarantee a precise detection the NIDS must detect packets at a wire speed. Network Intrusion Detection System (NIDS) is an important and practical tool for network security. However, with the recent trend of high-speed networks, the capability... [02 Jul 2008]
A Network Intrusion Detection System on IXP1200 Network Processors With Support for Large Rule Sets
White Paper It is aimed at detecting worms at high speeds by matching the payload of network packets against worm signatures at the lowest possible levels of the processing hierarchy (the microengines of an IXP1200 network processor). [30 Jun 2008]
White Paper: Deploying Network Taps With Intrusion Detection Systems
White Paper Because of the legitimate worry of false positives causing an intrusion prevention system to block valid network traffic, passive mode is still the most common mode of deployment - but security administrators and IDS vendors have been working on... [30 Jun 2008]
Recent Advances in Network Intrusion Detection System Tuning
White Paper The framework integrates both benign and malicious traffic, enabling generation of IP packet streams with diverse characteristics from the perspective of packet content (both header and payload), packet mix (order of packets in streams) and packet... [31 May 2008]
Applying Fast String Matching to Intrusion Detection
White Paper The performance of signature-based network intrusion detection tools is dominated by the string matching of packets against many signatures. The result is a system that matches many common packets 5 times faster with an average speedup of 50%. [21 May 2008]
