Threat Modeling based Penetration Testing: The Open Energy Monitor Case study
No full textCurrently, the widespread diffusion of intelligent objects connected to the Internet and continuously interacting with people is a fact. However, such a paradigm has a side effect in terms of privacy and security: personal data and the control of critical devices (eg. boiler, air conditioning, video surveillance, controlled gates, ...) are often demanded to home automation systems, often managed by non-expert users and, consequently, likely exposed to multiple security threats. This article follows a research line that aims to offer a systematic way to identify threats in the Internet of Things systems, and consequently plan penetration testing procedures, automated as much as possible, that outline possible security holes and help to gain awareness on the issues related to this new technologies. In this paper, we addressed a typical home system, the Open Energy Monitor, to demonstrate our methodology. In this analysis we focus on the MQTT protocol, commonly used for communication between IoT devices, proposing a complete Threat Model for this protocol. The main innovative contribution of this paper relates to the catalog of threats made available for MQTT-based devices (highly reusable in different environments) and on the planning of penetration tests, that relies on the adoption of a cyber threat intelligence database that collects common attack patterns, offered by MITRE
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Advancing ESSecA: a step forward in Automated Penetration Testing
No full textThe growing importance of Information Technology (IT) services is accompanied by a surge in security challenges. While traditional security tests focus on single applications, today's interconnected systems require a broader evaluation. Vulnerability Assessment and Penetration Testing (VAPT) is a method to tackle this, aiming to assess whole systems thoroughly. However, performing VAPT manually is time-consuming and costly. Therefore, there's a strong need for automating these processes. In response to these challenges, a novel methodology, named ESSecA built upon existing literature to guide the penetration testers during the assessment of a system based on threat intelligence mechanisms. This paper presents enhancements to the ESSecA methodology, including a formal Penetration Test Plan (PTP) model, a taxonomy for Penetration Test phases, and an innovative pattern match system integrated with a Tool Catalogue knowledge base used to improve the Expert System. These developments culminated in an algorithm facilitating the automatic generation of Penetration Test Plans, thus advancing the automation of security assessment processes
Variations on the Author
Full text link“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 linkWe 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 linkWe 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 textWe 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
