    Debido a su escalabilidad, las aplicaciones en la nube tienen una importante ventaja de costes para las empresas. En consecuencia, las empresas quieren tanto externalizar sus datos como obtener servicios de la nube. Sin embargo, dado que la mayoría de las empresas tienen políticas internas y requisitos de cumplimiento para operar y utilizar aplicaciones de software, el uso de aplicaciones en la nube crea un nuevo desafío para las empresas. La inclusión de aplicaciones en la nube equivale a la subcontratación de servicios en el sentido de que las empresas deben confiar en que el proveedor de aplicaciones en la nube aplicará los requisitos de cumplimiento interno en las aplicaciones adoptadas. La investigación ha demostrado que la confianza y el riesgo están estrechamente relacionados y son factores clave que influyen en la utilización de aplicaciones en la nube. Esta tesis pretende desarrollar una arquitectura en la nube que aborde este reto, trasladando la confianza en las configuraciones de cumplimiento del proveedor de aplicaciones en la nube a la cadena de bloques. Así, este trabajo pretende reducir el riesgo de adopción de las aplicaciones en la nube debido a los requisitos de cumplimiento. En esta tesis, la investigación de la ciencia del diseño se utiliza para crear la arquitectura para trasladar la confianza mencionada a la cadena de bloques. Un grupo de discusión determinó el alcance del trabajo. La base de conocimientos de este trabajo se construyó utilizando inteligencia artificial y una revisión sistemática de la literatura, y la arquitectura presentada se desarrolló y prototipó utilizando el método de desarrollo rápido de aplicaciones. Se utilizaron entrevistas guiadas semiestructuradas de método mixto para evaluar el enfoque de la arquitectura presentada y valorar las cualidades de reducción del riesgo de adopción. La tesis demostró que la arquitectura de software desarrollada podía trasladar la confianza del proveedor de la nube a la cadena de bloques. La evaluación de la arquitectura de software propuesta demostró además que el riesgo de adopción debido a las configuraciones de la nube basadas en el cumplimiento podía reducirse de "alto" a "bajo" utilizando la tecnología blockchain. Esta tesis presenta una arquitectura que desplaza la confianza para la implementación de configuraciones basadas en el cumplimiento de la normativa desde el proveedor de la nube a la cadena de bloques. Además, muestra que el cambio de confianza puede reducir significativamente el riesgo de adopción de las aplicaciones en la nube.Administración y Dirección de Empresa

    Unmanned Vehicle Systems & Operations On Air, Sea, Land is our fourth textbook in a series covering the world of Unmanned Aircraft Systems (UAS) and Counter Unmanned Aircraft Systems (CUAS). (Nichols R. K., 2018) (Nichols R. K., et al., 2019) (Nichols R. , et al., 2020)The authors have expanded their purview beyond UAS / CUAS systems. Our title shows our concern for growth and unique cyber security unmanned vehicle technology and operations for unmanned vehicles in all theaters: Air, Sea and Land – especially maritime cybersecurity and China proliferation issues. Topics include: Information Advances, Remote ID, and Extreme Persistence ISR; Unmanned Aerial Vehicles & How They Can Augment Mesonet Weather Tower Data Collection; Tour de Drones for the Discerning Palate; Underwater Autonomous Navigation & other UUV Advances; Autonomous Maritime Asymmetric Systems; UUV Integrated Autonomous Missions & Drone Management; Principles of Naval Architecture Applied to UUV’s; Unmanned Logistics Operating Safely and Efficiently Across Multiple Domains; Chinese Advances in Stealth UAV Penetration Path Planning in Combat Environment; UAS, the Fourth Amendment and Privacy; UV & Disinformation / Misinformation Channels; Chinese UAS Proliferation along New Silk Road Sea / Land Routes; Automaton, AI, Law, Ethics, Crossing the Machine – Human Barrier and Maritime Cybersecurity.Unmanned Vehicle Systems are an integral part of the US national critical infrastructure The authors have endeavored to bring a breadth and quality of information to the reader that is unparalleled in the unclassified sphere. Unmanned Vehicle (UV) Systems & Operations On Air, Sea, Land discusses state-of-the-art technology / issues facing U.S. UV system researchers / designers / manufacturers / testers. We trust our newest look at Unmanned Vehicles in Air, Sea, and Land will enrich our students and readers understanding of the purview of this wonderful technology we call UV.https://newprairiepress.org/ebooks/1035/thumbnail.jp

    Not invented here: Power and politics in public key infrastructure (PKI) institutionalisation at two global organisations.

    This dissertation explores the impact of power and politics in Public Key Infrastructure (PKI) institutionalisation. We argue that this process can be understood in power and politics terms because the infrastructure skews the control of organisational action in favour of dominant individuals and groups. Indeed, as our case studies show, shifting power balances is not only a desired outcome of PKI deployment, power drives institutionalisation. Therefore, despite the rational goals of improving security and reducing the total cost of ownership for IT, the PKIs in our field organisations have actually been catalysts for power and politics. Although current research focuses on external technical interoperation, we believe emphasis should be on the interaction between the at once restrictive and flexible PKI technical features, organisational structures, goals of sponsors and potential user resistance. We use the Circuits of Power (CoP) framework to explain how a PKI conditions and is conditioned by power and politics. Drawing on the concepts of infrastructure and institution, we submit that PKIs are politically explosive in pluralistic, distributed global organisations because by limiting freedom of action in favour of stability and security, they set a stage for disaffection. The result of antipathy towards the infrastructure would not be a major concern if public key cryptography, which underpins PKI, had a centralised mechanism for enforcing the user discipline it relies on to work properly. However, since this discipline is not automatic, a PKI bereft of support from existing power arrangements faces considerable institutionalisation challenges. We assess these ideas in two case studies in London and Switzerland. In London, we explain how an oil company used its institutional structures to implement PKI as part of a desktop standard covering 105,000 employees. In Zurich and London, we give a power analysis of attempts by a global financial services firm to roll out PKI to over 70,000 users. Our dissertation makes an important contribution by showing that where PKI supporters engage in a shrewdly orchestrated campaign to knit the infrastructure with the existing institutional order, it becomes an accepted part of organisational life without much ceremony. In sum, we both fill gaps in information security literature and extend knowledge on the efficacy of the Circuits of Power framework in conducting IS institutionalisation studies
