Texto completo da fonteWith the implementation and continuing research on information systems, such as Information Technology for the 21st Century (IT-21), Navy-Marine Corps Intranet (NMCI), and "Network-Centric warfare," there is little doubt that the Navy is becoming heavily dependent on information and information systems. Though much has been accomplished technically to protect and defend these systems, an important security issue has thus far been overlooked-the human factor. Information Assurance Risk Management (IARM) was a proposal to standardize the way DON personnel discuss, treat, and implement information assurance. IARM addresses the human security aspect of information and information systems in a regimented way to be understandable through all levels of the DON. To standardize the way DON personnel perceive information assurance, they must be taught what IARM is and how to use it. Can an IARM course be implemented in the DON, and if so at what level and to whom should it be taught?

Texto completo da fonteThis study focuses on information flows in the social grant process from a user experience perspective. The study was conducted with the South African Social Security Agency (SASSA), which is responsible for the administration and distribution of social grants to underprivileged citizens. Social grants help poor citizens to attain equitable income on a monthly basis. Grants play an increasingly important role in reducing poverty and inequality in South Africa, but are also subject to challenges like dependency, mismanagement and corruption. Information flow within SASSA is essential for the coordination of the grant process. The success of administering any social grant process depends largely on efficient communication practices and stable information technology. Communication among grant users requires the transfer of relevant information from its point of inception to the next point(s) of use. Government departments are transposing their paper-based systems into digital systems, which pose new implications for grant administration, however. Accordingly, the use of electronic services in government should mean faster information flow and, thus, more effective service delivery. The literature reveals, however, that non-technical aspects like user experience (UX) are essential in designing meaningful e-government systems. With a focus on user experience, this study uncovers the problems that SASSA and grant users face in the grant process and works toward possible solutions to resolve these problems. This research lays an important foundation in terms of gaining a better understanding of information flows, e-government, and user experiences in the grant process. This research is exploratory in nature and adopts a qualitative interpretivist approach. To gain a deeper understanding of the perspectives and experiences of grant users, the researcher employed the „Institutionalise User Experience in Government‟ (IUXG) methodology. The study targeted individuals that had knowledge of the social grants. A purposive sampling technique was used to select the research participants. Furthermore, the researcher adopted a thematic analysis method to code and analyse data. The findings of this study revealed the centrality of user experience in the grant process, notably in terms of the many challenges associated with information flow. The findings also revealed that factors such as social grant awareness, availability and use of information technology, digital divide, and grant accessibility bring enormous impact on grant processes and service delivery. The study contributes a landscape model for depicting the information flows in processing grants, and develops a broader understanding of how technology can help users to better disburse, access, and utilise grants. The study also informs e- government practitioners about the design and implementation of user-centred design with emphasis on information flows. Key Words: Information flows, social grants, e-government, and user experience.

Texto completo da fonteThe last years have seen a growing need of security and privacy in many aspects of communications, together with the technological progress. Most of the implemented security solutions are based on the notion of computational security, and must be kept continuously updated to face new attacks and technology advancements. To meet the more and more strict requirements, solutions based on the information-theoretic paradigm are gaining interest to support pure cryptographic techniques, thanks to their capacity to achieve security independently on the attacker’s computing resources, also known as unconditional security. In this work we investigate how information-theoretic security can be applied to practical systems in order to ensure data security and privacy. We first start defining information-theoretic metrics to assess the secrecy performance of realistic wireless communication settings under practical conditions, together with a protocol that mixes coding techniques for physical layer security and cryptographic solutions. This scheme is able to achieve some level of semantic security at the presence of a passive attacker. At the same time, multiple scenarios are considered. We provide a security analysis for parallel relay channels, thus finding an optimal resource allocation that maximizes the secrecy rate. Successively, by exploiting a probabilistic model checker, we define the parameters for heterogeneous distributed storage systems that permit us to achieve perfect secrecy in practical conditions. For privacy purposes, we propose a scheme which guarantees private information retrieval of files for caching at the wireless edge against multiple spy nodes. We find the optimal content placement that minimizes the backhaul usage, thus reducing the communication cost of the system.

Texto completo da fonteSearch is becoming the primary way in which people get information. In 2010, global Internet usage was over two billion people, with 92% of online adults using search engines to find information. Most commercial search engines (Google, Yahoo, Bing, etc.) provide their indexing and search services at no cost. The DoD can achieve large gains at a small cost by making public documents available to search engines. This can be achieved through the utilization of important design components and effective knowledge management. This thesis examines methods for making information available to search engines at the Naval Postgraduate School (NPS) and the Defense Technical Information Center (DTIC). In a large-scale project, over 200,000 documents were organized on the website dodreports.com. The results of this research revealed improvement gains of 8-20% for finding reports through commercial search engines during the first six months of implementation.
