DNSSEC en säkerhetsförbättring av DNS : en studie om Svenska kommuners syn på DNSSEC
Syftet med uppsatsen är att undersöka varför få svenska kommunerna valt att installera DNSSEC på sina domäner. DNS är en av de viktigaste protokollen på Internet och behövs för att sammanlänka IP-adresser med mer lättförståeliga adresser för oss människor. DNS skapades utan att tänka på säkerheten, för att kunna göra DNS säkrare utvecklades ett säkerhetstillägg till DNS detta fick namnet DNSSEC.Vi har använt oss av litteraturstudie, experiment och intervjuer för att skapa en djupare kunskap och förståelse om hur DNS och DNSSEC fungerar samt besvara varför få kommuner har valt att installera DNSSEC.Under vår litteraturstudie läste vi om flera sårbarheter i DNS och hur dessa kan utnyttjas för att utsätta en organisation för attacker såsom cacheförgiftning och MITM. Vi testade dessa sårbarheter och bekräftade det. Efter installationen av DNSSEC kunde inte angreppen längre genomföras i vår testmiljö.Under intervjuerna kom vi fram till att den vanligaste orsaken att kommuner inte väljer att installera DNSSEC är okunskap om tillvägagångsättet för en installation och att de tycker deras nuvarande DNS fungerar bra, det blir då ingen prioriterad fråga.
Riskanalys inom intrångsäkerhet på webbplatser
Attacker och intrång på webbservrar är idag vanligt förekommande. Webben gör
det lätt för hackare, knäckare och andra inkräktare att hitta sårbara servrar,
och det finns gott om tips att hämta för den som vill lära sig hur man gör
intrång. Det finns ett flertal olika intrångsmetoder som utnyttjar olika typer
av svagheter i datorsystemen. Denna uppsats inriktar sig på svagheter i
webbplatsernas serverskriptsystem, dess skriptkod och konfiguration. Syftet är
att undersöka huruvida intrång kan göras med endast en webbläsare via
webbplatsens offentliga webbsidor.
Genom att kombinera tre olika metoder - litteraturundersökning, en enkät och
ett experiment - undersöker uppsatsen hur serverskriptintrång fungerar.
IT för att bygga nätverk : Att komplettera personliga relationer med IT
Globalization has lead to evolvement of teamwork between companies and their customers. One reason for this change is the growth of the IT community and the propagation of the Internet. This in turn has lead to faster communication within business networks and also a higher degree of integration between companies.The purpose of this thesis is to describe IT can be used to develop and support networks formed around IT corporations. IT also aim at describing what impact usage of IT within personal networks has on usage of IT within business networks. The thesis is limited to IT-companies using IT artifacts, not only for communication within its organization, but also communicating with its customers and other IT-companies.
Webbsystem för matprisjämförelser
This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.
FRÅN ÖPPENHET OCH NÄRVARO-TILL DISTANS OCH KONTROLL : Att medicineras och att administrera ur ett patient- och sjuksköterskeperspektiv
Title: From openness and presence to distance and control: to be medicated and to administrate from a patient and nurse perspective.Background: Within forensic psychiatric care the patients are admitted against their will, under heavy security with long term treatments. Self-care seems, based on scientific studies, to be dependent on what the nurses involved can provide. Emphasis should focus on a humane and respectful approach when the patient is exposed to coercive measures.Aim: From a patient and nurse perspective describe experiences of beeing medicated with and to administrate antipsychotic drugs within the psychiatric inpatient care.Method: Interviews with patients and nurses, which were analyzed using qualitative content analysis with an inductive approach.Results: Patients experience frustration over not beeing able to participate in or influence descisions made regarding their neuroleptic treatment. The neuroleptic treatment is described as a coercive measure and is characterized as an experience of losing control and independence. Nurses? experiences of administering antipsychotics were described as having to do what is needed for the long term benefit of patients? well-being.
Remburser och andra säkerhetsarrangmang vid internationell handel
AbstractWe live in a world today that is characterized by the Internet. We can get hold of people on the other side of the globe whenever we want and we can purchase what ever we want, from who ever we want, anytime we want. This development has made it important to find systems of dealing with the payment in a safe and secure way, both for a private person as well as for a company, when you do transactions with people far away, and those systems is the core of this essay. As a private person you sometimes need to transfer money to family members who live abroad and you can then use clean payments. This means that banks all over the world has systems which makes it easier when their customs wishes to transfer money abroad.
Liv i den övergivna trädgården? : Tro och sekularisering i Sverige, speglad mot dominerande teorier om sekulariseringsprocesser
This master thesis summarizes contemporary theories on secularization processes in the Western world, and compares these with the example of Sweden, which by many scholars is considered to be the most secularized country in the Western world.I do this by dividing the most influential theorists in five different groups. In each group I explain how the theorists formulate and motivate their positions. These groups are:1) The secularization paradigm, where secularization always accompanies modernization. (Therorists: Steve Bruce and Peter Berger (in the 1960s)2) The paradigm basically accepted, but revised to depend on existential security, rather than modernisation as such. (Pippa Norris and Ronald Inglehart)3) Religion returned in the public sphere.
Generationsskifte : Särskilt om gåva och blandade fång
All small- and medium-sized family owned enterprises need to sooner or later undergo a change of ownership. When the elder generation is approaching their retirement they have to make a choice; either hand over the business to the younger generation or sell it to an outsider. The succession of the family owned business can create a life long dilemma for the entrepreneur. From the view of taxation there are, according to current legislation, no reasons to plan the succession to the younger generation. If no preparation has been done, the optional law system concerning inheritance will divide the property left.
Ekonomiskt bistånd : Ett geografiskt lotteri?
Denna studie syftar till att granska variationer i bedömningar och beslut om ekonomiskt bistånd utifrån vilken betydelse den enskilda organisationens riktlinjer har för dessa. Utifrån syftet, och med stöd av tidigare forskning på området, valdes vinjettstudien som metod. Ett identiskt typfall, gällande en fiktiv ansökan om ekonomiskt bistånd, skickades ut till samtliga kommuner i Västra Götalands län, med undantag för Göteborgs kommun. Vinjetten riktades till socialsekreterare som i sin vardag arbetar med handläggning av ekonomiskt bistånd och totalt erhölls svar från 16 olika kommuner. Resultatet påvisar stora skillnader i både bedömningar och beslut mellan de olika kommunerna vilket verifierar de tidigare studier som gjorts.
Journalistik på liv och död En kvalitativ studie om journalisters syn på medias roll i asylprocesser!
The main purpose of this thesis is to explore journalists? views of the role of journalism in the asylum processes. The potentially problematic phenomenon is growing, and its spread will affect the way publishing decisions are made in the future. The subject is new and foreign to many journalists, and little to no research has previously been done on the subject. Our study will therefore provide new insight in the field of journalism ethics.We have conducted a qualitative study based on interviews with eight Swedish journalists who in oneway or another have reported on threatened asylum seekers.
Materialhantering till och från robot
Material handling is a term that includes all kinds of handling of material from a raw product to a finished one. ABB is active in the following segments; foundry, packaging and palletizing, metal industry and plastics industry.The demands for efficiency and reliability have been set very high in the industrial sector. Optimizing of the material handling will give the company higher cost-effectiveness. Around the robot there are different kinds of material flows, to optimize the cycle time, consisting of carriages combined in different ways.Motion Control is a complex system with main functions such as; positioning, synchronizing, indexing and more. The products in the system need to cooperate to make these functions possible therefore integration of motor- and servo products are important.
Pedagogers föreställningar om krigsdrabbade flyktingbarn
According to the immigration service forecasts Sweden faces large refugee influxes in the coming years. This means that educators in the kindergarten, preschool and school, will meat children from the war torn countries. In this study, the purpose is to find out the educators different conceptions of war-affected refugee children, because my theory is that their beliefs influence their actions. I wanted to get answers to their beliefs about the difficulties or challengers that children and educators may be faced with. Furthermore, I wanted to know what educators envisioned about their own role?s importance to the war affected refugee children and their perceptions of the Swedish culture, environment, language and school.
Kvinnors drivkrafter för att lämna en kriminell livsstil : val, uppbrott och förändring
The purpose of this essay is to analyse the descriptions of young girls' experiences of internet contacts, which have led up to sexual abuse. The aim is to give additional understanding and knowledge concerning grooming. Grooming means that somebody gets in contact with someone else with the intention of committing sexual violations at a later stage. In most cases this concerns adults who contact children. We have chosen to confine ourselves to focusing on the grooming on internet that has happened to girls. By means of thematic analyses of texts from the books Jag kände mig speciell, grooming på internet, 2012 and Alexandramannen, vår tids största nätsexhärva, 2009, we have found certain themes and linked them up with previous research-work and also theory of social psychology.

?Å ena sidan, så är vi helt oumbärliga, å andra sidan så behöver vi ingenting? : En kvalitativ studie av hur fritidspedagoger upplever att deras yrkesroll påverkats av att fritidshemmet blivit en del av skolan
In the early nineties leisure-time pedagogic establishments moved in to school. The aim of the study is to try to find out how leisure-time pedagogues, who have been working for a long time, experience the moving of their establishment in to school and how this affect their practical work and their profession.The study is based on interviewes with four leisure-time pedagogues, who all have been working before?and therefore have experienced the time before?during and after their establishment moved in to school.These interviewes were recorded and later fully transcribed in preparation of analysis. Data was analysed with the help of the sociology of Pierre Bourdieu as a basis. Findings of the study suggest that the leisure-time pedagogues find it positive to be able to cooperate with teachers and other professional groups working in school, they explain how it enabels themselves to see pupils from a different angle and for others working in school to see pupils from a leisure-time pedagogue angle.Some of the pedagogues explain that they find it hard to work with big groups of pupils, or in small surfaces, which they did not have to do before their establishment moved into school.
