Generating historical network logs for cyber range exercises
Get PDFCyberangrep blir stadig mer vanlige, og studier viser at trusler fra Advanced Persistance Threats (APT'er), øker eksponentielt. Trening av cybersikkerhetsprofesjonelle i realistiske miljøer er avgjørende for å være forberedt på å håndtere en virkelig hendelse. Disse treningsmiljøene kan kalles Cyber Ranger (CR); hvor deres hensikt er å tilby et trygt og isolert miljø der cybersikkerhetspersonell kan øve uten fare for å påvirke relaterte produksjonssystemer.
En CR består av en infrastruktur av klienter og servere som etterligner en virksomhet eller organisasjon. En del av å gjøre scenariet realistisk er å ha realistiske nettverkslogger for cybersikkerts-personellet å analysere under øvelser i Cyber Rangen. Forskningen i denne oppgaven omfatter metoder og teknikker for å generere historiske nettverkslogger, da dette emnet ikke er omfattet i tidligere publisert forskning. Denne prosjektet presenterer en løsning til generering av nettverkslogger for cyberøvelser, med evnen til å produsere logger som spenner over en lang periode, generert på betydelig kortere tid.
Ved å følge forskningsmetodikken Design Science Research (DSR), definerer prosjektet kravene til en nettverkslogggenerator. Til slutt presenterer den en utviklet generator for nettverkslogger som genererer logger med nevnte funksjonalitet. Det utviklede generatoren manipulerer systemklokken til å gå raskere enn normalt og simulerer brukeratferd ved hjelp av nettleseremulering på systemet for å generere trafikk, alt mens generatoren fanger all trafikken på nettverksadapteren. Artifakten er testet i et lukket nettverksmiljø med et gitt antall andre klienter på nettet, og resultatene fra loggene er analysert og sammenliknet med normaltrafikk generert på normalt vis. Nettverkslogg-generatoren, som er den ferdige artifakten etter dette prosjektet, kan generere nettverkslogger som PCAP-filer for cyberøvelser med tilpassbare start- og stopptider, forskjellige arbeidsplaner for trafikkdistribusjoner, og en hastighet på generering som varierer fra 10 til 30 ganger raskere enn sanntid.Cyber attacks are increasingly more common, and studies show that threats from Advanced Persistence Threats (APTs), are increasing exponentially. Training cybersecurity professionals in realistic environments is crucial to be prepared for handling a real incident. These training environments can go by the name Cyber Range (CR); whose intention is to provide a safe and isolated environment where cyber security personnel can exercise without risk of affecting any related production systems.
A CR consists of an infrastructure of clients and servers emulating a business or organization in a realistic manner. A part of making the scenario realistic is to have realistic network logs for a blue team to analyze. The research contributions of this thesis include investigating methods and techniques for generating historical network data, as this topic is highly lacking in current literature. This thesis presents an approach to a generator for creating network logs for cyber exercises, with the capability of producing logs spanning over a long period of time, generated in a significantly shorter time.
Following the Design Science Research (DSR) methodology, the thesis defines the requirements for a network log generator and presents a developed artifact that successfully generates logs with said functionality. The developed artifact utilizes system clock manipulation and simulates user behavior using browser emulation on the system to generate traffic, all while the generator captures all the traffic on the network interface. The proposed artifact was tested in a closed environment with several other clients, with its results analyzed and compared to a baseline of normally generated traffic. The artifact can successfully generate network logs as PCAP files for cyber exercises with customizable start and stop times, different work schedules for traffic distributions, and a speed ranging from 10 to 30 times faster than in real time
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn 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.
