Lightweight Federation of Non-Cooperating Digital Libraries

This dissertation studies the challenges and issues faced in federating heterogeneous digital libraries (DLs). The objective of this research is to demonstrate the feasibility of interoperability among non-cooperating DLs by presenting a lightweight, data driven approach, or Data Centered Interoperability (DCI). We build a Lightweight Federated Digital Library (LFDL) system to provide federated search service for existing digital libraries with no prior coordination. We describe the motivation, architecture, design and implementation of the LFDL. We develop, deploy, and evaluate key services of the federation. The major difference to existing DL interoperability approaches is one where we do not insist on cooperation among DLs, that is, they do not have to change anything in their system or processes. The underlying approach is to have a dynamic federation where digital libraries can be added (removed) to the federation in real-time. This is made possible by describing the behavior of participating DLs in an XML-based language that the federation engine understands. The major contributions of this work are: (1) This dissertation addresses the interoperability issues among non-cooperating DLs and presents a practical and efficient approach toward providing federated search service for those DLs. The DL itself remains autonomous and does not need to change its structure, data format, protocol and other internal features when it is added to the federation. (2) The implementation of the LFDL is based on a lightweight, dynamic, data-centered and rule-driven architecture. To add a DL to the federation, all that is needed is observing a DL\u27s interaction with the user and storing the interaction specification in a human-readable and highly maintainable format. The federation engine provides the federated service based on the specification of a DL. A registration service allows dynamic DL registration, removal, or modification. No code needs to be rewritten or recompiled to add or change a DL. These notions are achieved by designing a new specification language in XML format and a powerful processing engine that enforces and implements the rules specified using the language. (3) In this thesis we explore an alternate approach where searches are distributed to participating DLs in real time. We have addressed the performance and reliability problems associated with other distributed search approaches. This is achieved by a locally maintained metadata repository extracted from DLs, as well as an efficient caching system based on the repository

DSpace Manual: Software version 1.5

DSpace is an open source software platform that enables organizations to: - Capture and describe digital material using a submission workflow module, or a variety of programmatic ingest options - Distribute an organization's digital assets over the web through a search and retrieval system - Preserve digital assets over the long term This system documentation includes a functional overview of the system, which is a good introduction to the capabilities of the system, and should be readable by nontechnical personnel. Everyone should read this section first because it introduces some terminology used throughout the rest of the documentation. For people actually running a DSpace service, there is an installation guide, and sections on configuration and the directory structure. Note that as of DSpace 1.2, the administration user interface guide is now on-line help available from within the DSpace system. Finally, for those interested in the details of how DSpace works, and those potentially interested in modifying the code for their own purposes, there is a detailed architecture and design section

Implementation of a digital workspace

Projecte de final de master realitzat en col.laboració amb l'empresa Bull s.aThis document is the summary of my final assignment project report. In this report, I described my internship, the problems encountered and the solutions chosen. It includes also an analysis of my planning and the budget involved. This project aimed at producing a digital workspace which will provide for all pedagogical and management needs in the educational context. This digital workspace is designed to propose a unique and secure gateway to all on line services offered to the users. It will respect the single authentication principle and each application will manage by itself its own access right to its services. Within the team of developers, I was in charge of the data integration. It included the introduction of new data in the main database through an automated process, the management of data modification and the data forwarding to other application. This central process allows all the application to be synchronized at any moment with the data provided by the government. In the report, I present the functionality expected from the portal, and the requisite express by the client. Then, from a technical point of view, I introduce different portals and explain the reason behind our choice within all available. I also highlight a few technical points about the authentication system and the users management system. In another section of the report, I present my own work related to the data integration. From the extraction by the government to the transfer into the different applications, the data are passed from an application to another through different applications I designed and developed. A presented in-depth analysis of the requisites explains the reason of the design used. In the last part, the Gantt diagram and the budget presentation achieves the presentation of my internship

Design of an Intrusion Detection System (IDS) and an Intrusion Prevention System (IPS) for the EIU Cybersecurity Laboratory

Cyber Security will always be a subject of discussion for a long time to come. Research has shown that there is massive growth of cyber-crime and the currently available number of Cyber Security experts to counter this is limited. Although there are multiple resources discussing Cyber Security, but access to training in practical applications is limited. As an institution, Eastern Illinois University (EIU) is set to start Masters of Science in Cyber Security in Fall 2017. Then the challenge is how EIU will expose students to the practical reality of Cyber Security where they can learn different detection, prevention and incidence analysis techniques of cyber-attacks. In addition, students should have the opportunity to learn cyber-attacks legally. This research proposes a solution for these needs by focusing on the design of firewall architecture with an Intrusion Detection System (IDS) and Intrusion Prevention System (IPS) for the EIU Cyber Security Laboratory. This thesis explores different up to date techniques and methods for detection and prevention of cyber-attacks. The overall outcome of this research is to design a public testing site that invites hackers to attack for the purpose of detection, prevention and security incidence analysis. This public firewall might empower students and instructors with practical cyber-attacks, detection techniques, prevention techniques, and forensics analysis tools. It may also provide the knowledge required for further research in the field of Cyber Security
