A risk analysis and risk management methodology for mitigating wireless local area networks (WLANs) intrusion security risks

Every environment is susceptible to risks and Wireless Local Area Networks (WLANs) based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard are no exception. The most apparent risk of WLANs is the ease with which itinerant intruders obtain illicit entry into these networks. These intrusion security risks must therefore be addressed which means that information security risk analysis and risk management need to be considered as integral elements of the organisation’s business plan. A well-established qualitative risk analysis and risk management methodology, the Operationally Critical Threat Asset and Vulnerability Evaluation (OCTAVE) is selected for conducting the WLAN intrusion security risk analysis and risk management process. However, the OCTAVE risk analysis methodology is beset with a number of problems that could hamper a successful WLAN intrusion security risk analysis. The ultimate deliverable of this qualitative risk analysis methodology is the creation of an organisation-wide protection strategy and risk mitigation plan. Achieving this end using the OCTAVE risk analysis methodology requires an inordinate amount of time, ranging from months to years. Since WLANs are persistently under attack, there is a dire need for an expeditious risk analysis methodology. Furthermore, the OCTAVE risk analysis methodology stipulates the identification of assets and corresponding threat scenarios via a brainstorming session, which may be beyond the scope of a person who is not proficient in information security issues. This research was therefore inspired by the pivotal need for a risk analysis and risk management methodology to address WLAN intrusion attacks and the resulting risks they pose to the confidentiality, integrity and availability of information processed by these networks.

Intelligence in 5G networks

Over the past decade, Artificial Intelligence (AI) has become an important part of our daily lives; however, its application to communication networks has been partial and unsystematic, with uncoordinated efforts that often conflict with each other. Providing a framework to integrate the existing studies and to actually build an intelligent network is a top research priority. In fact, one of the objectives of 5G is to manage all communications under a single overarching paradigm, and the staggering complexity of this task is beyond the scope of human-designed algorithms and control systems. This thesis presents an overview of all the necessary components to integrate intelligence in this complex environment, with a user-centric perspective: network optimization should always have the end goal of improving the experience of the user. Each step is described with the aid of one or more case studies, involving various network functions and elements. Starting from perception and prediction of the surrounding environment, the first core requirements of an intelligent system, this work gradually builds its way up to showing examples of fully autonomous network agents which learn from experience without any human intervention or pre-defined behavior, discussing the possible application of each aspect of intelligence in future networks

Fuelling the zero-emissions road freight of the future: routing of mobile fuellers

The future of zero-emissions road freight is closely tied to the sufficient availability of new and clean fuel options such as electricity and Hydrogen. In goods distribution using Electric Commercial Vehicles (ECVs) and Hydrogen Fuel Cell Vehicles (HFCVs) a major challenge in the transition period would pertain to their limited autonomy and scarce and unevenly distributed refuelling stations. One viable solution to facilitate and speed up the adoption of ECVs/HFCVs by logistics, however, is to get the fuel to the point where it is needed (instead of diverting the route of delivery vehicles to refuelling stations) using "Mobile Fuellers (MFs)". These are mobile battery swapping/recharging vans or mobile Hydrogen fuellers that can travel to a running ECV/HFCV to provide the fuel they require to complete their delivery routes at a rendezvous time and space. In this presentation, new vehicle routing models will be presented for a third party company that provides MF services. In the proposed problem variant, the MF provider company receives routing plans of multiple customer companies and has to design routes for a fleet of capacitated MFs that have to synchronise their routes with the running vehicles to deliver the required amount of fuel on-the-fly. This presentation will discuss and compare several mathematical models based on different business models and collaborative logistics scenarios

El tratamiento documental de las fotografías de prensa, ante el dolor de los demás: un estudio comparativo de las fotografías de las portadas El País y The New York Times (2001-2011)

El tratamiento documental de las fotografias de prensa, ante el dolor de los demas. Un estudio comparativo de las fotografias de las portadas El Pais y The New York Times (2001-2011)presentada por Alicia Parras Parras Bajo la direccion de la Doctora Julia Rodriguez CelaEsta tesis doctoral trata de responder a algunas de las cuestiones planteadas en el libro de Susan Sontag Ante el dolor de los demás: ¿por qué en ocasiones se muestra en una fotografía el dolor del otro? ¿influye la distancia a la hora de mostrar ese dolor? Para ello, se comparan las fotografías principales de portada de dos periódicos de referencia: El País (España) y The New York Times (Estados Unidos) desde los terribles atentados del 11-S hasta la Primavera Árabe en 2011, estas fotografías seleccionadas se refieren a conflictos bélicos, ataques terroristas y catástrofes naturales. En cuanto a la metodología de trabajo, la tesis engloba tres estudios diferentes: 1.- Estudio historiográfico del fotoperiodismo y su evolución desde el nacimiento de la fotografía, a través de fuentes archivísticas y bibliográficas, hasta llegar a nuestros días.2.- Estudio sobre la ética en el fotoperiodismo, las leyes y los códigos deontológicos en España y Estados Unidos y un breve repaso a la obra de Susan Sontag Ante el dolor de los demás, en el que además del pertinente estudio bibliográfico, se llevan a cabo entrevistas en profundidad a expertos como fotógrafos (Gervasio Sánchez, Miguel Trillo) o editores gráficos (Marisa Flórez), entre otros.3.- Estudio estadístico-documental de las portadas de El País y The New York Times. Una vez analizadas todas las portadas seleccionadas en el programa informático IBM- SPSS siguiendo las propuestas de análisis documental de Félix del Valle, se procede a la extracción de datos estadísticos y al comentario de los conflictos bélicos, atentados terroristas y catástrofes naturales más representados y representativos. También se introducen brevemente los antecedentes históricos de los eventos comentados para complementar el comentario a través de la consulta de fuentes bibliográficas, como libros y artículos
