En studie av inbyggda brandväggar - Microsoft XP och Red Hat Linux

Detta kandidatarbete utreder hur väl två operativsystems inbyggda brandväggar fungerar i symbios med en användares vanligaste tjänsteutnyttjande på Internet, samt att se hur likartade de är i sitt skydd från hot. De två operativsystemen som vi utgick ifrån var Microsoft Windows XP samt Red Hat Linux 8.0. Den hypotes vi arbetat kring lyder enligt följande: De två inbyggda brandväggarna är i stort likartade rörande skydd från hot på Internet och uppfyller användarnas tjänsteutnyttjande. De metoder vi använt, för att svara på vår frågeställning, har delats upp i ett funktionalitetstest och ett säkerhetstest. I funktionalitetstestet provades de vanligaste Internettjänsterna med den inbyggda brandväggen och ifall det uppstod några komplikationer eller ej. De två inbyggda brandväggarna genom gick i säkerhetstestet skannings- och svaghetskontroll via ett flertal verktyg. Genom resultatet kan vi konstatera att de inbyggda brandväggarna klarar av de vanligaste tjänsterna på Internet, men att en skillnad föreligger hos dem vad gäller exponeringen ut mot Internet.

Dataspel, en naturlig del av folkbibliotek? ? En fallstudie på Helsingborgs stadsbibliotek

This paper aims to investigate how Helsingborg?s city library?s visi-tors feel about computer games being available for lending and in which way computer gamers see Helsingborg?s city library as a resource. This was examined first with a study of 100 of the library?s visitors and then with five interviews with computer gamers and an interview with the librarian responsible for purchasing games.The study showed that most visitors were neutral to having games at the library and of the ones that were not neutral many more were positive than negative. Of the five gamers who were inter-viewed, there were several who had borrowed games in the past.

Säkerhet och integritet i närfältskommunikation

Context. In today?s society we use smart cards in many areas, NFC is a smart card technology that allows contactless interaction between a reader and the tag, the tag is often in the form of a card. NFC can be used for various payment methods or as access card to a building which makes life easier. In previous studies, the technique has proven to be weak to attacks using an NFC reader connected to a computer.

Kommunikativ interaktion i den synkrona elektroniska referenstjänsten : Den interpersonella kommunikationen mellan användare och bibliotekarie

The aim of this master thesis is to gain greater knowledge of interpersonal communication. This study explores on one hand how interpersonal communication can be used as an important part of reference work in a Swedish electronic synchronous reference service, and on the other how interpersonal communication affects the relationship between user and librarian. By using communication theory and establishing a positive relational contact with the user in the electronic environment, the outcome of the reference encounter can be successful for both the librarian and the user. Furthermore, the importance of recognising relational barriers is of great relevance to the relational contact. The scope of this master thesis is to find what relational factors are used and can be used in the interaction between user and librarian.

??Auktorisation och ackreditering inom Försvarsmakten : En studie i nyttan av en standardiserad process för att hantera informationssäkerhet

???Information Technology is an essential part of the society today, not least in large ???organisations dealing with sensitive information. An example of such an organisation is the Swedish Armed Forces which indeed is in the need of ways to ensure information security in their Information Technology systems. The means which is used is an authorisation and accreditation process.All Information Technology systems go through a life cycle which includes realisation, usage, development and liquidation. In the Swedish Armed Forces the lifecycle is an authorisation process.

Vem styr mitt arbete? Förändrade arbetsuppgifter vid datorisering av körschema

Abstract This report is our bachelor thesis. Our work has taken place at a galvanising company in Sölvesborg. The company faced major changes, of which one was a computerisation process. The new system could involve changes in work practice and in specific tasks, affecting the workers. If the coming system was to support work, from the production personnel?s perspective, we felt a legitimate participation in the development and design of the future work practice, was a requirement that was not met. During our ethnographical studies we noted that conflicts arose between production and administrative -personnel.

Ledarskap inom ramen för ett systemutvecklingsprojekt - fokus på en arbetsprocess med stöd i Vattenfallsmodellen

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

Datorspel - en lek eller sport? : En studie om hur tre svenska dagstidningar framställer e-sport och datorspel 2000-2013

This essay examines how three big Swedish newspapers depicts e-sports and computer gaming and how the depiction change during 2000-2013. The study will also examine whether e-sports is being portrayed as competitive sport. The purpose is to investigate which attitudes that can be identified towards computer gaming and its culture in major newspapers such as Aftonbladet, Dagens Nyheter and Svenska Dagbladet and how these attitudes eventually changed over time. The sources that will be used in both the quantitative and qualitative analysis are based on web articles, mainly because the paper editions does not provide much, if any, information about computer gaming and e-sports and also because of the convenience of being able to quickly find articles to study. Results indicate that computer gaming is being depicted in a clear negative fashion during 2000-2006, and that the depiction of e-sports is somewhat positive but not as glorifying as for the years 2007-2013. During this period, there is a apparent tendency of e-sports being introduced to readers who are unfamiliar with the gaming culture. As for the attitudes towards computer gaming, the depiction is still somewhat negative, mainly because the debate about computer games and violence was revived because of several acts of violence in shape of school massacres and mass murder.

De autistiska barnens dataprogram - hur bör de vara?

This report presents a study of the basic criteria for computer programmes that may be consideredadequate for aiding children with autism in their education and upbringing. I have based thisstudy on descriptions, opinions and proposals from people who deal with treatment and/orother issues concerning children with autism, as well as relevant literature.The study has been carried out in a major Swedish metropolitan municipality. The intervieweeswere civil servants from this municipality and representing different institutional endeavourson the issue of autism.I used a combination of both quantitative and qualitative techniques, as there was need for bothstandardization and qualitative variation. The main aim of the study was to seek suggestionson how computer programmes should be. That is, if they are to be considered appropriate föraiding children with autism develop their personality.The general conclusion of this study is that computer programmes, that may be consideredappropriate for the above mentioned purpose, should have certain characteristics of whichpedagogic usefulness and user suitability are of primary importance..

Autentisering i programvaruapplikationer

Dagens människa är ytterst beroende av webbtjänster och med tiden har det blivit fler och viktigare tjänster som startat upp på internet. Viktiga tjänster som internetbanker. Oftast är det bara ett användarnamn och ett lösenord som krävs för att bli autentiserad så man skulle kunna tro att användarna håller hårt i sina lösenord och att de väljer starka/unika lösenord. För många verkar det dock, enligt källor, vara ett besvär. Borde man ha associeringar för att lätt komma ihåg sitt lösenord eller är det för riskabelt? Det har visat att många tycker om att använda ord som förknippas med webbsidan.

Elektroniskt publicerad litteratur: Beskrivningen av dess för- och nackdelar i svensk bibliotekspress 2000-2004.

During the changes of time, the stipulations for the existence of books and libraries also change. With technical advances come new possibilities, and the option to publish literature electronically is one of them. The purpose of this Master's thesis is to answer the question how the advantages and disadvantages of electronically published literature is described and constructed. To further deepen the analysis these questions were asked: What aims are the electronically published literature said to achieve? Why are the electronically published literature said to achieve these aims? And who are favoured/disfavoured by electronically published literature? The analyzed publications are four Swedish library related publications: Biblioteksbladet, Dik-forum, Ikoner and Nya Ciceron.

Metadata för det digitala biblioteket : Objektbeskrivning av elektroniska resurser

Cataloguing electronic documents makes new demands on libraries. This thesis discusses the metadata formats Dublin Core and MARC which are, individually or in combination, commonly used for object description in the digital library.The formats are studied with particular emphasis on characteristics such as underlying reasoning (ambitions during the development of the formats), flexibility (possibilities of expansion and adaption to new demands) and interoperability (cooperation between different metadata formats). The formats are dealt with in their context, i.e. we discuss what types of documents the formats are meant to describe, what environment they were originally created for, what functions they are meant to fill (to find, identify, select and acquire/obtain entities), and also how these factors are related. The Swedish projects SAFARI (which uses Dublin Core) and NetSök (which uses MARC) are presented briefly.

Den gemensamma utrikes och säkerhetspolitiken- Ett neo-funktionalistiskt perspektiv

This essay aims to explore the development of the common foreign and security policy within the European Union as well as the recent addition of the post of High representative in the field of the common foreign and security policy. This essay will attempt to achieve this trough exploring the questions; how have the aim of the European foreign policy developed, how the forms of cooperation has within this field developed and finally what impact will the recent addition of a high representative for the common foreign and security have. My aim is to answer these questions with the help of neo-functionalism.The results that came out of this essay point to the direction that the neo- functionalist premise about spill over effects and the notion about increased supranational influence turn out to have some validity in them. The study has shown that during the time the cooperation within the field of foreign and security policy have developed it is possible to see that supranational institutions will gain influence when the scope of integration within a policy area widens and deepens..

Uppförsäljning - en väg till ökade snittköp

The Swedish consumer electronic industry has recently experienced an increasingly intensive price war. The price war has forced some operators in the business to declare bankruptcy, as the only way to compete has been by driving down prices. A challenge that retail chains in the consumer electronics industry is facing is to increase their margins. If store personnel can success with upselling, the companies will increase their profits. The purpose of this paper is to examine if the sales people in the consumer electronic industry can influence the customer to buy a more expensive product and what the effects the upselling has on the customers' attitudes.
