Wireless Intrusion Detection Sytem
… of security. This paper describes a Wireless Intrusion Detection System (WIDS) that provides additional security for 802.11b wireless networks. WIDS provides intrusion detection that can react to potential threats and locate an intruder through the use of intelligent access points equipped …

Battery-Based Intrusion Detection
… warning system via a mobile host-based form of intrusion detection that can alert security administrators to protect their corporate network(s) by a novel technique that operates through the implementation of smart battery-based intrusion detection (B-bid) on mobile devices, such as PDAs, …

Using VProbes for intrusion detection
Many current intrusion detection systems (IDSes) are vulnerable to intruders because they are running under the same operating system (OS) as a potential attacker. Since an attacker will often be attempting to co-opt the OS, this leaves the IDS vulnerable to subversion by the attacker. While some …

Water intrusion in underground structures
This thesis presents a study of the permissible groundwater infiltration rates in underground structures, the consequences of this leakage and the effectiveness of mitigation measures. Design guides and codes do not restrict, address or make clear recommendations for permissible inflows in …

Intrusion Detection In Wireless Sensor Networks
There are several applications that use sensor motes and researchers continue to explore additional applications. For this particular application of detecting the movement of humans through the sensor field, a set of Berkley mica2 motes on TinyOS operating system is used. Different sensors such as …

The Effectiveness of Intrusion Detection Systems
… the following hypothesis: "The effectiveness of intrusion detection systems can be improved by rethinking the way the IDS is managed and by adopting effective and systematic implementation approaches."<br/><br/>This submission introduces the work done to show the validity of this hypothesis. It …

Phytoforensics: Applications in vapor intrusion assessment
<p>"Vapor intrusion (VI) occurs when contaminants in the vapor phase migrate in the shallow subsurface and enter buildings through cracks, seams, and gaps and has been recognized as a serious human-health threat as occupants are exposed to potentially harmful concentrations over long periods of …

Intrusion detection for industrial control systems
… a need for strong cybersecurity anomaly and intrusion detection for these systems; however, due to the complexity and diversity of ICSs, well defined and reliable anomaly and intrusion detection systems are still being developed. Machine learning approaches for anomaly and intrusion detection …

Heuristics for Improved Enterprise Intrusion Detection
… The current approach is to deploy a set of intrusion detection sensors (IDSs) in various locations throughout the network and on strategic hosts. Unfortunately, the available intrusion detection technologies generate an overwhelming volume of false alarms, making the task of identifying …

Incremental Bayesian segmentation for intrusion detection
… by a Unix host in order to detect potential intrusion attacks. Sequences of system calls generated by privileged processes are analyzed using incremental Bayesian segmentation in order to detect anomalous activity. Theoretical analysis of various aspects of the algorithm and empirical …

Attack development for intrusion detector evaluation
An important goal of the 1999 DARPA Intrusion Detection Evaluation was to promote the development of intrusion detection systems that can detect new attacks. This thesis describes UNIX attacks developed for the 1999 DARPA Evaluation. Some attacks were new in 1999 and others were stealthy versions …

Multi-Vector Portable Intrusion Detection System
This research describes an intrusion detection system designed to fulfill the need for increased mobile device security. The Battery-Sensing Intrusion Protection System (B-SIPS) [1] initially took a non-conventional approach to intrusion detection by recognizing attacks based on anomalous …

Multi-Agent Reinforcement Learning for Intrusion Detection
… hand-coded solutions emulating simple misuse intrusion detection and a hybrid approach using misuse and anomaly methods. We found that our learning approach generates better results than the simple hand-coded misuse methods. Even though the hybrid hand-coded approach shows slightly better …

Network Intrusion Detection: Monitoring, Simulation And Visualization
This dissertation presents our work on network intrusion detection and intrusion sim- ulation. The work in intrusion detection consists of two different network anomaly-based approaches. The work in intrusion simulation introduces a model using explicit traffic gen- eration for the packet level …
