    Propuesta ChatBot para la empresa Acai Spa con enfoque en Ciberseguridad

    No full text
    La presente propuesta aborda un problema crítico en Acai SpA relacionado con la seguridad del sistema de atención automatizada mediante chatbot. Lo que conlleva una carga laboral adicional de funciones de algunos colaboradores dentro de la organización. En la actualidad, esta herramienta opera sin medidas de ciberseguridad suficientes, exponiendo información sensible de clientes a riesgos significativos como robo de datos, suplantación de identidad y ataques a la infraestructura. Mediante un análisis de vulnerabilidades y el uso de marcos normativos como ISO/IEC 27001 y NIST SP 800-53, se diseña una solución de ciberseguridad que considera controles técnicos (TLS, MFA, cifrado de datos), organizacionales (políticas, roles, respaldo) y metodológicos (Scrum, ciclo PHVA). Este enfoque asegura una respuesta progresiva y estructurada, optimizando la protección de datos y el cumplimiento legal. Se complementa con un análisis económico que estima un bajo costo mensual frente a los beneficios proyectados en prevención de incidentes. La propuesta entrega una hoja de ruta viable y alineada a las necesidades de seguridad, eficiencia y trazabilidad de la organización. Hoy podemos ver que las empresas que operan bajo el modelo Software como Servicio (SaaS), como es el caso de Acai SpA, enfrentan crecientes desafíos en materia de ciberseguridad, especialmente cuando interactúan con los clientes a través de interfaces automatizadas como los chatbots. Acai SpA es una organización chilena de mediana escala dedicada a servicios de atención al cliente y soporte digital. Su infraestructura tecnológica incluye un chatbot web como canal principal de comunicación con usuarios, implementado mediante una API REST y conectado a una base de datos en la nube. Este chatbot gestiona una amplia gama de datos sensibles: nombres, RUT, correos electrónicos, preferencias de servicios y registros de conversaciones, sin contar con controles robustos de seguridad. Actualmente, el entorno del chatbot presenta múltiples debilidades estructurales y procedimentales que elevan el nivel de exposición a incidentes de ciberseguridad. Entre las principales vulnerabilidades detectadas destacan: la ausencia de cifrado en tránsito y en reposo, la falta de autenticación multifactor (MFA) para accesos administrativos, la inexistencia de segmentación de red, el almacenamiento de registros (logs) en texto plano y sin políticas de retención, y una API que no valida adecuadamente las entradas, lo cual habilita vectores de ataque como inyecciones de código y secuestro de sesión. El análisis efectuado evidencia que la arquitectura tecnológica no implementa prácticas de seguridad alineadas a estándares internacionales como ISO/IEC 27001, NIST SP 800-53 o los lineamientos de OWASP para APIs. Además, el manejo de datos personales se encuentra en incumplimiento de las normativas chilenas, como la Ley 19.628 sobre protección de datos personales y la Ley Marco de Ciberseguridad (Ley 21.719). Dado este panorama, el presente proyecto propone el diseño de una solución integral de ciberseguridad orientada específicamente al chatbot, mediante la incorporación de controles técnicos (TLS 1.3, AES-256, MFA, validación de entradas, monitoreo de logs), organizacionales (políticas de seguridad, gestión de incidentes), y procedimentales (respaldo automatizado, control de acceso basado en roles). Esta intervención se enmarca dentro de un enfoque ágil basado en Scrum y en el ciclo de mejora continua PHVA, asegurando así una implementación iterativa, auditable y alineada a las necesidades reales de la empresa. El fortalecimiento del chatbot no solo mejora la postura de seguridad de Acai SpA, sino que también protege la confianza de los clientes, mitiga riesgos legales, y eleva el nivel de madurez tecnológica de la organización frente a amenazas persistentes en el entorno digital actual

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
