An investigation into information security practices implemented by Research and Educational Network of Uganda (RENU) member institution

Educational institutions are known to be at the heart of complex computing systems in any region in which they exist, especially in Africa. The existence of high end computing power, often connected to the Internet and to research network grids, makes educational institutions soft targets for attackers. Attackers of such networks are normally either looking to exploit the large computing resources available for use in secondary attacks or to steal Intellectual Property (IP) from the research networks to which the institutions belong. Universities also store a lot of information about their current students and staff population as well as alumni ranging from personal to financial information. Unauthorized access to such information violates statutory requirement of the law and could grossly tarnish the institutions name not to mention cost the institution a lot of money during post-incident activities. The purpose of this study was to investigate the information security practices that have been put in place by Research and Education Network of Uganda (RENU) member institutions to safeguard institutional data and systems from both internal and external security threats. The study was conducted on six member institutions in three phases, between the months of May and July 2011 in Uganda. Phase One involved the use of a customised quantitative questionnaire tool. The tool - originally developed by information security governance task-force of EDUCAUSE - was customised for use in Uganda. Phase Two involved the use of a qualitative interview guide in a sessions between the investigator and respondents. Results show that institutions rely heavily on Information and Communication Technology (ICT) systems and services and that all institutions had already acquired more than three information systems and had acquired and implemented some of the cutting edge equipment and systems in their data centres. Further results show that institutions have established ICT departments although staff have not been trained in information security. All institutions interviewed have ICT policies although only a few have carried out policy sensitization and awareness campaigns for their staff and students.Te

Web information systems: A study of maintenance, change and flexibility

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Information Systems (IS’s) have provided organisations with huge efficiency gains and benefits over the years; however an outstanding problem that is yet to be successfully tackled is that of the troublesome maintenance phase. Consuming vast resources and thwarting business progression in a competitive global market place, system maintenance has been recognised as one of the key areas where IS is failing organisations. Organisations are too often faced with the dilemma of either replacement or the continual upkeep of an unwieldy system. The ability for IS’s to be able to adapt to exogenous influences is even more acute today than at any time in the past. This is due to IS’s namely, Web Information Systems (WIS’s) increasingly and continually having to accommodate the needs of organisations to interconnect with a plethora of additional systems as well as supporting evolving business models. The richness of the interconnectivity, functionalities and services WIS’s now offer are shaping social, cultural and economic behaviour on a truly global scale, making the maintenance of such systems and evermore pertinent issue. The growth and proliferation of WIS’s shows no sign of abating which leads to the conclusion that what some have termed as the ‘maintenance iceberg’ should not be ignored. The quandary that commercial organisations face is typically driven by two key aspects; firstly, systems are built on the cultural premise of using fixed requirements, with not enough thought or attention being paid to systems abilities to deviate from these requirements. Secondly, systems do not generally cope well with adapting to unpredictable change arising from outside of the organisations environment. Over the recent past, different paradigms, approaches and methods have attempted to make software development more predictable, controllable and adaptable, however, the benefits of such measures in relation to the maintenance dilemma have been limited. The concept of flexible systems that are able to cope with such change in an efficient manner is currently an objective that few can claim to have realised successfully. The primary focus of the thesis was to examine WIS post-development change in order to empirically substantiate and understand the nature of the maintenance phase. This was done with the intention to determine exactly ‘where’ and ‘how’ flexibility could be targeted to address these changes. This study uses an emergent analytical approach to identify and catalogue the nature of change occurring within WIS maintenance. However, the research framework design underwent a significant revision as the initial results indicated that a greater emphasis and refocus was required to achieve the research objective. To study WIS’s in an appropriate and detailed context, a single case study was conducted in a web development software house. In total the case study approach was used to collect empirical evidence from four projects that investigated post-development change requests in order to identify areas of the system susceptible to change. The maintenance phases of three WIS projects were considered in-depth, resulting in the collection of over four hundred change requests. The fourth project served as a validation case. The results are presented and the findings are used to identify key trends and characteristics that depict WIS maintenance change. The analytical information derived from the change requests is consolidated and shown diagrammatically for the key areas of change using profile models developed in this thesis. Based on the results, the thesis concludes and contributes to the ongoing debate that there is a discernable difference when considering WIS maintenance change compared to that of traditional IS maintenance. The detailed characteristics displayed in the profile models are then used to map specific flexibility criteria that ultimately are required to facilitate change. This is achieved using the Flexibility Matrix of Change (FMoC) tool which was developed within the remit of this research. This tool is a qualitative measurement scheme that aligns WIS maintenance changes to a reciprocal flexibility attribute. Thus, the wider aim of this thesis is to also expand the awareness of flexibility and its importance as a key component of the WIS lifecycle

Customizable teaching on mobile devices in higher education

Every teacher struggles with the student’s attention when giving a lecture. It is not easy to meet every single student at its knowledge level in a seminar group, and it becomes nearly impossible in huge university lectures with hundreds of students. With the spread of mobile devices among students, Audience Response Systems (ARS) proved as an easy and cheap solution to activate the audience and to compare the students’ real knowledge base with the lecturer’s estimation. Today, lecturers are able to choose between a huge variety of different ARSs. But as every lecturer has a very individual teaching style, he or she is not yet able to create or customize their individual audience response teaching scenario within a single system. The available systems are quite similar to each other and mostly support only a handful of different scenarios. Therefore, this work identified the abstract core elements of ARSs and developed a model to create individual and customizable scenarios for the students’ mobile devices. Teachers become able to build their individual application, define the appearance on the students’ phones in a scenario construction kit and even determine the scenario’s behavior logic. Two ARS applications were implemented and used to evaluate the model in real lectures for the last four years. A first ARS was integrated into the university’s learning management system ILIAS and provided lecturers with basic question functionalities, whereas a second and more advanced stand-alone version enabled lecturers to use personal scenarios in a variety of lecture settings. Hence, scenarios like quizzes, message boards, teacher feedback and live experiments became possible. The approaches were evaluated from a technical, student and lecturer perspective in various courses of different areas and sizes. The new model showed great results and potential in customization, but the implementation reached its limits as it lacked in performance scalability for complex scenarios with a large amount of students

Annual Report of the University, 2000-2001, Volumes 1-4

Message from the President Thank you for joining me in this look back over the past year at the University of New Mexico. It was a year filled with activity, accomplishment and challenge, and this is our opportunity to reflect back on that year. In 2000-2001 we engaged in a University-wide strategic planning process that called on the energies and talents of hundreds of individuals- faculty, staff, students and members of our broader community. The plan, which will be completed in Fall 2001, will serve as our roadmap for the future and will guide our efforts to capitalize on the opportunities and to meet the challenges of the next several years. This process has encouraged us to examine closely our mission and our values, who we are and what we aspire to become. It has given us reason to be proud of our past and cause to think seriously about how we must change in the future. While this was a year for looking ahead, it was also a year of significant accomplishment. For example, we launched a comprehensive set of programs designed to enrich the academic and social experiences of our undergraduate students. We began the implementation of Freshman Learning Communities where small cohorts of students study and learn together in a common set of courses under the guidance of a senior faculty scholar. We reorganized our advisement systems, we undertook the construction or renovation of student-centered facilities on campus, and we created new support systems to enhance student academic success. It was a year in which our support of faculty, staff and students was our highest priority. Through the support of the New Mexico Legislature, faculty and staff received significant salary increases. A new health benefits plan for graduate assistants was implemented. Our Staff as Students program enabled more than 40 staff members to obtain UNM degrees. And, a Center for Scholarship in Teaching and Learning was established to assist faculty in their efforts to develop more effective teaching skills. Finally, this was a year in which UNM dramatically expanded its role in the local community and throughout the state. Never before has the University been as active or as visible in meeting its public responsibility as it was in 2000-2001. From its active participation in economic development initiatives, to its involvement in K-12 educational improvement efforts, to its significant leadership role in health care delivery, UNM demonstrated its ability to help the state meet its most pressing social challenges. And, as UNM took on a more visible role in supporting the state\\u27s citizens, the support for UNM was returned in kind. This year, annual giving to the University rose to a record 35.3 million dollars, a 40% increase over just two years ago. All told, it has been a gratifying and successful year. However, we cannot allow our past accomplishments to mask the continued challenges facing this University. Neither will we allow these challenges to dominate our thinking and diminish out pride in what the University has achieved. So we will savor our successes and continue to move forward. As always, we thank you for sharing our dreams and for supporting the University of New Mexico. Sincerely, William C. Gordon, Presiden

The evaluation of academic electronic bulletin boards for communication and training : HCI factors in the UK and Saudi Arabia

Electronic networks services have become essential tools for the academic community. One of the services provided has been academic electronic bulletin boards (EBBs), and the use of EBBs has increased dramatically during the last decade. One question concerns the possible application of EBBs as a means both for communication and for remote training. A series of experiments were conducted during 1991, 1992, and 1993 with the aim of examining the use of EBBs for these purposes. The first experiment was carried out to investigate whether users experience problems in using EBBs. The next extended this to see how students evaluated EBBs for communication and training purposes. The main focus of the work was BUBL. After this second experiment, modifications were made to the BUBL data and a further experiment was carried out. A different group of students looked at the modified material, and also compared it with US data using different software. The fourth experiment compared the usability of a menu-based interface (dBase III +) and a hypertext interface (HyperCard) from a student's viewpoint. It was followed by an investigation of icons to find out how well different icons could be recognised and the possibility of using them for language-independent instructions. Finally, the characteristics and problems of GULFNET users were examined. The evaluation has demonstrated the general acceptability of EBBs and their likely value for training purposes. This leads to a discussion of how an EBB might best be developed for use in communication and training on GULFNET
