Honeyd - A Os Fingerprinting Artifice, Craig Valli

Research outputs pre 2011

The research looks at the efficiency of the honeyd honeypot system to reliably deceive intruders. Honeypots are being used as frontline network intelligence and forensic analysis tools. A honeypots ability to reliably deceive intruders is a key factor in gathering reliable and forensically sound data. Honeyd's primary deceptive mechanism is the use of the NMAP fingerprint database to provide bogus OS fingerprints to would be intruders. Tests conducted by the author on honeyd's ability to provide bogus fingerprints sees 78% of 704 signatures invalidated under heavy probing. However, the tests left 152 viable signatures for producing hardened honeypot designs.

Ordering Genetic Algorithm Genomes With Reconstructability Analysis, Stephen Shervais, Martin Zwick

Complex Systems Faculty Publications and Presentations

The building block hypothesis implies that genetic algorithm effectiveness is influenced by the relative location of epistatic genes on the chromosome. We find that this influence exists, but depends on the generation in which it is measured. Early in the search process it may be more effective to have epistatic genes widely separated. Late in the search process, effectiveness is improved when they are close together. The early search effect is weak but still statistically significant; the late search effect is much stronger and plainly visible. We demonstrate both effects with a set of simple problems, and show that infonnation-theoretic …

A Linux-Based Graphical User Interface For The Creation And Reading Of The Frame Format: Version 2.4, Muhammed Aoun

Theses : Honours

To gain further knowledge of how the universe began, a new international co-operated project wishes not only to "see" stars exploding, but also to "hear" the explosion. It is theorised that the ability to "listen" to an explosion is possible by detecting gravitational waves. Gravitational waves are omitted when a star explodes, travelling through the cosmos at an exceptional speed. It is estimated that a gravity wave takes only 40 milliseconds to pass through the earth. Thus the aim of this international collaboration is to detect a gravitational wave. To accurately detect such waves, there needs to be several global …

Computer Assisted Screening Of Digital Mammogram Images, John Terry Sample

LSU Doctoral Dissertations

The use of computer systems to assist clinicians in digital mammography image screening has advantages over traditional methods. Computer algorithms can enhance the appearance of the images and highlight suspicious areas. Screening provides a more thorough examination of the images. Any computer system that does screening of digital mammograms contains components to address multiple tasks such as: image segmentation, mass lesion detection and classification, and microcalcification detection and classification. This dissertation provides both effective and efficient improvements to existing algorithms, which segment mammogram images and locate mass lesions. In addition, we provide a new algorithm to evaluate and report the …

Measuring Software Size For Continuous Process Improvement, Claire O'Sullivan

Theses

This thesis looks at how the size of a software product can be measured. It looks at current software sizing methods (LOC and FPA) and shows that they are not sufficient in today’s rapidly changing environment. The COSMIC-FFP method is introduced and an overview of how it works is given. The hypothesis to be tested in this thesis is whether COSMIC-FFP is an accurate, repeatable sizing method that when applied to any type of software project produces a size measure that can be used to predict the effort required to complete the project.

This thesis investigates the use of the …

Sip Message Compression Technique For Efficient Multimedia Services In 3g Wireless Communications, Valerie Kenneally

Theses

The direction of the global cellular industry is primarily determined by two standardisation bodies, the 3rd Generation Partnership Project (3GPP) (in Europe and Asia) and 3GPP2 (in North America). Both of these standardisation bodies are currently specifying a core network to deliver IP based multimedia services over 3G wireless networks. One of the fundamental building blocks of this IP based multimedia core network is the use of SIP (Session Initiation Protocol) as the control protocol. The radio resource, that is the available frequency spectrum, in wireless communication systems remains a limiting factor in terms of the bandwidth available to an …

An Intelligent Early Warning System For Software Quality Improvement And Project Management, Xiaoqing Frank Liu, Gautam Kane, Monu Bambroo

Computer Science Faculty Research & Creative Works

One of the main reasons behind unfruitful software development projects is that it is often too late to correct the problems by the time they are detected. It clearly indicates the need for early warning about the potential risks. In this paper, we discuss an intelligent software early warning system based on fuzzy logic using an integrated set of software metrics. It helps to assess risks associated with being behind schedule, over budget, and poor quality in software development and maintenance from multiple perspectives. It handles incomplete, inaccurate, and imprecise information, and resolve conflicts in an uncertain environment in its …

Agent Based Intrusion Detection And Response System For Wireless Lans, Mohan K Chirumamilla, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Wireless LAN technology, despite the numerous advantages it has over competing technologies, has not seen widespread deployment. A primary reason for markets not adopting this technology is its failure to provide adequate security. Data that is sent over wireless links can be compromised with utmost ease. In this project, we propose a distributed agent based intrusion detection and response system for wireless LANs that can detect unauthorized wireless elements like access points, wireless clients that are in promiscuous mode etc. The system reacts to intrusions by either notifying the concerned personnel, in case of rogue access points and promiscuous nodes, …

Patterns And Trends Of Soil Climate Regimes And Drought Events In The Northern Great Plains, William J. Waltman, Stephen M. Goddard, S. E. Reichenbach, Mark Svoboda, Michael Hayes, J. S. Peake

School of Computing: Conference and Workshop Papers

Drought is the dominant process of crop loss nationally and within Nebraska. Nearly twothirds of the 18.6 million harvested acres are covered by crop insurance (USDA/RMA, 2003; USDA/NASS, 2003). For the most part, Nebraska’s crop losses range from $50 to 75 million in non-drought years, but the losses approach nearly $200 million in drought years, such as 2000. The past growing season (2002) crop losses are projected to greatly exceed $375 million in Nebraska and more than $4 billion nationally (USDA/RMA, 2003). The analysis and understanding of drought processes in the Great Plains is an important component to developing drought …

Ethical Issues In Open Source Software, Frances Grodzinsky, Keith W. Miller, Marty J. Wolf

School of Computer Science & Engineering Faculty Publications

In this essay we argue that the current social and ethical structure in the Open Source Software (OSS) Community stem from its roots in academia. The individual developers experience a level of autonomy similar to that of a faculty member. Furthermore, we assert that the Open Source Software Community's social structure demands benevolent leadership. We argue that it is difficult to pass off low quality open source software as high quality software and that the Open Source development model offers strong accountability. Finally, we argue that Open Source Software introduces ethical challenges for universities and the software development community.

An Architectural Pattern For Adaptable Middleware Infrastructure, Jason J. Mitchell

UNF Graduate Theses and Dissertations

Middleware technologies change so rapidly that designers must adapt existing software architectures to incorporate new emerging ones. This project proposes an architectural pattern and guidelines to abstract the communication barrier whereby allowing the developer to concentrate on the application logic.

We demonstrate our approach and the feasibility of easily upgrading the middleware infrastructure by implementing a sample project and three case studies using three different middlewares on the .NET framework.

A Deception Based Framework For The Application Of Deceptive Countermeasures In 802.11b Wireless Networks, Suen Yek

Theses : Honours

The advance of 802.11 b wireless networking has been beset by inherent and in-built security problems. Network security tools that are freely available may intercept network transmissions readily and stealthily, making organisations highly vulnerable to attack. Therefore, it is incumbent upon defending organisations to take initiative and implement proactive defences against common network attacks. Deception is an essential element of effective security that has been widely used in networks to understand attack methods and intrusions. However, little thought has been given to the type and the effectiveness of the deception. Deceptions deployed in nature, the military and in cyberspace were …

United States Diplomacy In The Age Of The Internet, Allison S. Greene

Graduate Program in International Studies Theses & Dissertations

The dynamics of international relations are constantly changing, and the origin of an extraordinary amount of that change can be traced to what has been coined the ‘Information Revolution.’ It is a revolution as profound and as significant as Gutenberg's invention of moveable metal type, and may result in social and political consequences of comparable magnitude. One of the most significant and far-reaching implications of this phenomenon is the emergence of the Internet. Since its inception, there have been many claims and assertions about existing and potential repercussions of the Internet within the diplomatic realm.

The purpose of this work …

Report On The Third Acm/Ieee Joint Conference On Digital Libraries (Jcdl), Michael L. Nelson

Computer Science Faculty Publications

The Third ACM/IEEE Joint Conference on Digital Libraries (JCDL 2003) was held on the campus of Rice University in Houston, Texas, May 27 - 31. Regarding the merging of the ACM and IEEE conference series, in the JCDL 2002 conference report published last year in D-Lib Magazine Edie Rasmussen noted, "Perhaps by next year...no one will remember that it wasn't always so" [1]. Judging by the number of participants I met who did not know that the ACM and IEEE used to hold separate digital library conferences, Rasmussen's prediction has come to pass.

Digitization In An Archival Environment, Sally Mckay

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

Introduction

Cultural institutions such as museums, libraries, archives, and historical societies house remarkable collections of cultural artifacts. It is the responsibility of the staff working for those institutions to preserve, protect and provide responsible stewardship for the materials, and to the best of their ability, provide continued long-term access (Russell, 2000).

Advances in technology allow institutions to provide expanded access and education; however, there are important priorities that must be addressed prior to embarking on a digital conversion project.

Digitization in an archival environment includes taking a physical object or analog item, such as an art object, a tape recording, …

Teaching A Multiagent Systems Class With Game Days: Designs And Lessons Learned, Leen-Kiat Soh

School of Computing: Technical Reports

In the Fall semester of 2002, I introduced and taught a class in Multiagent Systems. The class was aimed for seniors (with special permission) and graduate students in Computer Science, covering some breadth and depth of issues in multiagent systems. One of the requirements was participation in four Game Days. On each Game Day, student teams competed against each other in games related to issues such as auction, task allocation, coalition formation, and negotiation. This article documents my designs of and lessons learned from these Game Days. The Game Days were very successful. Through role-playing, the students were motivated and …

Inter-Domain Dynamic Routing In Multi-Layer Optical Transport Networks, Xi Yang, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Next-generation optical transport networks will automatically and dynamically provision end-to-end connections. In this paper, we study the problem of inter-domain dynamic routing under a multi-layer multi-domain network model, which allows the end-to-end connections to be set up not only across multiple routing domains but also through two transport layers: the optical layer and the digital layer. In this model, a connection can traverse the domain boundary either through optical bypass or through optical-electrical-optical (O/E/O) processing. We propose an inter-domain dynamic routing scheme with modest time complexity to address the problem from an algorithmic perspective.

A Novel Fiber Delay Line Buffering Architecture For Optical Packet Switching, Lin Li, Stephen Scott, Jitender S. Deogun

School of Computing: Conference and Workshop Papers

Due to the lack of optical random access memory, optical fiber delay line (FDL) is currently the only way to implement optical buffering. Feed-forward and feedback are two kinds of FDL structures in optical buffering. Both have advantages and disadvantages. In this paper, we propose a more effective hybrid FDL architecture that combines the merits of both schemes. The core of this switch is the arrayed waveguide grating (AWG) and the tunable wavelength converter (TWC). It requires smaller optical device sizes and fewer wavelengths and has less noise than feedback architecture. At the same time, it can facilitate preemptive priority …

A New Efficient Algorithm For Solving The Simple Temporal Problem, Lin Xu, Berthe Y. Choueiry

School of Computing: Conference and Workshop Papers

In this paper we propose a new efficient algorithm, the Δ STP-solver, for computing the minimal network of the Simple Temporal Problem (STP). This algorithm achieves high performance by exploiting a topological property of the constraint graph (i.e., triangulation) and a semantic property of the constraints (i.e., convexity) in light of the results reported by Bliek and Sam-Haroud [1], which were presented for general CSPs and have not yet been applied to temporal networks. Importantly, we design the constraint propagation in Δ STP-solver to operate on triangles instead of operating on edges and implicitly guarantee the decomposition of …

Instance Based Attribute Identification In Database Integration, Ee Peng Lim, Cecil Chua, Roger Hsiang-Li Chiang

Research Collection School Of Computing and Information Systems

Most research on attribute identification in database integration has focused on integrating attributes using schema and summary information derived from the attribute values. No research has attempted to fully explore the use of attribute values to perform attribute identification. We propose an attribute identification method that employs schema and summary instance information as well as properties of attributes derived from their instances. Unlike other attribute identification methods that match only single attributes, our method matches attribute groups for integration. Because our attribute identification method fully explores data instances, it can identify corresponding attributes to be integrated even when schema information …

Developing A Catalogue Of Errors And Evaluating Its Impact On Software Development, Indrit Troshani

Theses: Doctorates and Masters

The development of quality software is of paramount importance, yet this has been and continues to be an elusive goal for software engineers. Delivered software often fails due to errors that are injected during its development. Correcting these errors early in the development or preventing them altogether can, therefore, be considered as one way to improve software quality. In this thesis, the development of a Catalogue of Errors is described. Field studies with senior software engineering students are used to confirm that developers using the Catalogue of Errors commit fewer errors in their development artifacts. The impact of the Catalogue …
