Mobile Application Security Scenario for the BUTCA Education Platform
No full textThis thesis focuses on the design and implementation of two educational scenarios aimed at mobile application security, intended for use within the BUTCA (Brno University of Technology Cyber Arena) training platform. The first scenario targets penetration testing of a deliberately vulnerable Android application, demonstrating common security flaws based on the OWASP Mobile Top 10 methodology. The second scenario addresses incident handling and mobile application security analysis using forensic tools, malware detection, and network traffic analysis. The thesis also includes a theoretical overview of current mobile security threats, methodologies, and testing techniques. The proposed scenarios were designed to support practical, hands-on learning and enhance cybersecurity training. Following implementation, the scenarios were tested and evaluated using analytical tools available in the BUTCA platform. The results demonstrate their value in cybersecurity education, particularly in developing students’ ability to identify, analyze, and respond to mobile application threats effectively
Mobile Application Security Scenario for the BUTCA Education Platform
No full textTato diplomová práce se zabývá návrhem a implementací dvou výukových scénářů zaměřených na bezpečnost mobilních aplikací, které jsou určeny pro školící platformu BUTCA (Brno University of Technology Cyber Arena). První scénář je zaměřen na penetrační testování zranitelné Android aplikace, přičemž jsou demonstrovány nejčastější zranitelnosti podle metodiky OWASP Mobile Top 10. Druhý scénář se věnuje bezpečnostní analýze a reakci na incidenty v prostředí mobilních aplikací, s využitím nástrojů pro forenzní analýzu, detekci malware a analýzu síťového provozu. Součástí práce je rovněž teoretická část, která popisuje aktuální hrozby, metodologie a techniky používané v oblasti mobilní bezpečnosti. Výukové scénáře byly navrženy s důrazem na praktičnost, použitelnost ve výuce a podporu interaktivního učení. Po jejich implementaci proběhlo testování a vyhodnocení efektivity prostřednictvím analytických nástrojů platformy BUTCA. Výsledky potvrzují přínos scénářů pro vzdělávání studentů v oblasti informační bezpečnosti, zejména při rozvoji jejich schopností identifikovat, analyzovat a řešit bezpečnostní hrozby v mobilních aplikacích.This thesis focuses on the design and implementation of two educational scenarios aimed at mobile application security, intended for use within the BUTCA (Brno University of Technology Cyber Arena) training platform.

Access control system for carsharing application
No full textThe bachelor thesis is devoted to access systems with an emphasis on carsharing applications, both from a theoretical point of view, where it analyzes their advantages and disadvantages and uses cryptographic primitives, and also from a practical point of view, where the practical part includes the design of an access system and its subsequent implementation. Bluetooth Low Energy technology and Near field communication are also used in the bachelor thesis, which is again described from a theoretical point of view, especially the key concepts of these technologies, as well as its practical use for access systems

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
