Att skydda sin IT-miljö mot olika typer av intrång och attacker som till exempel trojaner,skadliga Java applets eller DoS attacker med hjälp av brandväggar och antivirusprogramär två viktiga lager i skalskyddet.I den här uppsatsen undersöks hur väl ett Intrusion Prevention System skulle kunna fungera som ett ytterligare lager i skalskyddet. Fokus ligger på hur väl IPS-systemet klarar av att avvärja attacker, hur mycket tid som går åt till konfigurering och drift för att få ett fungerande IPS samt hur prestandan i nätverket påverkas av implementationen. För att mäta hur väl IPS systemet klarar av att upptäcka och blockera attacker utförs två experiment där ett mindre nätverk attackeras på olika sätt. I det första experimentet skyddas infrastrukturen av en brandvägg och klienterna är utrustade med antivirusprogram. I det andra experimentet genomförs samma attacker igen fast med ett Snort IPS implementerat i nätverket.Resultatet av de genomförda experimenten visar att en IPS klarar att blockera ca 87% av attackerna, men nätverksprestandan påverkas negativt.

Saab Bofors Dynamics AB is looking for ways to let the employees work wireless in the future. The security in Wireless Local Area Networks (WLAN) has not been considered very reliable, but new standards and protocols have been developed to enhance the security in WLAN. Since most wireless components soon will have built in support for wireless communication, it is important to have a model to deal with secure wireless communication ready. This is necessary because it is important to protect the company?s information related systems, ensure contingency in the daily work and maintaining the trust of the market and the authorities.

Corporate Social Responsibility is a concept whereby companies integrate social and environmental concerns into their core business and in their interaction with stakeholders on a voluntarily basis. The purpose with our thesis is to study how Swedish insurance companies work with Corporate Social Responsibility and to analyse the underlying strategies of the companies? social, environmental and economical activities. We will analyse where, how and for whom value can be created with CSR. Where does the value creation take place, how can it be created through these activities and who will benefit from Corporate Social Responsibility? Theories point out that companies need to assemble and value the total package of benefits to be able to create successful corporate initiatives.

Denna studie belyser svårigheten för teknik och virtuell geografi att nå ut till mottagaren genom en kartläggning av e-postens geografi. För att skapa förståelse och fånga den osynliga processen bakom e-postens geografi  utgår uppsatsen dels från teorin Actor Network Theory (ANT) och dels från intervjuer.Under studiens gång uppstod ny förståelse för e-postens komplexitet och ledde fram till en reviderad syn. I början av uppsatsarbetet betraktades e-posten enbart utifrån sin funktion som aktant och intermediarie men i takt med att undersökningen fortgick framkom att den samtidigt, utöver dessa funktioner, fungerar e-posten som ett heterogent nätverk med betydelsefulla komponenter såsom aktörer och aktanter. Enligt uppsatsens konklusioner är e-postens trajektoria beroende av den strategi som producenten använder under skapandet av elektroniska meddelanden. Ett kontinuerligt arbete mellan producent och konsument krävs för att e-postens trajektoria ska upprätthållas och leda fram till att det elektroniska meddelande som löper igenom det virtuella nätverket når sitt syfte..

Knowledge is of great importance for organizations and it is seen as an important competitive advantage to effectively preserve knowledge within an organisation. The upcoming retirement of employees born in the 1940s poses a threat because it is believed to result in a knowledge drain. The problem of preserving knowledge within the organization lies in the fact that it is partly tacit, and therefore not possible to write down or communicate in words. The purpose of this thesis is to investigate how tacit knowledge is created in the Swedish Ministry for Foreign Affairs and the implications thereof. We examine the following research questions: Of what significance is the creation and reproduction of tacit knowledge for the Swedish Foreign Ministry? Which factors influence the creation and reproduction of tacit knowledge and why? A case study of the Swedish Ministry for Foreign Affairs has been conducted.

Utifrån rapporter från bl.a. Riksidrottsförbundet (2007) går det att fastställa att aktivitetsytor som planeras för barn och unga idag inte används jämlikt. Dagens planering tenderar att gynna killar i högre utsträckning än tjejer. Examensarbetet Breaking the Habitual ? Ett gestaltningsförslag för Hagebys nya aktivitetscentrum ställer sig kritiskt till detta och strävar efter att bryta denna planeringsstruktur.

This report explains the need to develop a configuration manager that handles transmission equipment which exists in the Swedish Defence telecommunications network. The configuration module will display the configurations and compatibility among the equipment and their software which are all part of the network.Also included in this report are tools, methods and results for the development of a prototype for the configuration manager. The prototype consists fundamentally of a database assisted by a user friendly website.The transmission equipment handles a lot of important transmission of information and is in the hands of a department of SAAB, OFGCA, by orders from the Swedish Defence Materiel Administration (FMV). Within the work included in this order exists a continuous update of both software and hardware which the equipment consists of. Therefore it?s highly important that there is a monitoring of which of the software and hardware is compatible with one another, ensuring that the functions of the system work properly.The consistent updating has resulted in compatibility issues between components and because of this, a need for a configuration manager has arisen..

The community Vessigebro, in Falkenberg and its surrounding areas housing one percent of all dairy cattle and two percent of all pigs in Sweden. This means that there is a large amount of manure as a basis for producing biogas in the area. A number of farmers have therefore formed a cooperative named Vessigebro biogas and started the project Green Vessigebro, with the goal of creating the conditions for a more profitable and more sustainable agriculture production.The study deals with the conditions and sale opportunities of the feasibility study Green Vessigebro. The study has looked at the work that was previously carried out for the biogas that could be produced on the farms in Vessigebro, The main pipeline for natural gas on the Swedish west coast and its operators, the Swedish Competition Act , Electricity Act , Natural Gas Act, the District Heating Act , Sustainability Act , previously proposed measures, municipality interest in biogas from Vessigebro , possible collaborations, possible sale opportunities and perform calculations with data from the municipality Ljungby for a suggested transportation of biogas between Vessigebro and Ljungby.The study shows that there are several interesting sale opportunities for biogas from Vessigebro. The production and use of biogas in Sweden is increasing and the trend seems set to continue.

Detta kandidatarbete undersöker hur digitala spel kan skapas med någon annans synsätt. Vi ville se vad som hände om vi försökte göra spel på ett posthumanistiskt sätt och om detta hade förändrat något. Det har uppkommit speciella möjligheter och konsekvenser under processen, det har även dykt upp frågor. En av dessa frågor är hur skapandet av varelser inom digitala spel kan utföras. Likväl har det under projektet skett diskussioner och tester runt hur ett verktyg för detta ändamål skulle kunna fungera.

Due to poorly functioning local and regional markets, the smallholders in San Francisco, Petén, were dependent on intermediaries that took advantage of the smallholder?s distance to markets. In an attempt to secure income and strengthen their bargaining position, 189 smallholders joined forces through the creation of a social smallholder network, held together by a community based enterprise. This enterprise was initiated in 2011 with the help of government incentive programmes and NGOs that within a few years will leave the enterprise to auto regime. This study treats the sustainability of a community forest based enterprise, Chachaklum, in northern Guatemala. The study identifies factors that enable smallholders to organize themselves in order to obtain business practices that support an improved standard of living.

The acquisition process as an object for research and empirical studies have increased in importance during the past decade. The purpose of this thesis is to investigate this process further. This was done by reviewing previous research covering the area of mergers and acquisitions. Seven key factors that should be considered in an acquisition process emerged; acquisition project management, planning, communication between the acquirer and the potential target, goal alignment within management, company-cultures, a trade-off between a certain speed in integrating the companies and consideration of the employees, and finally the follow-up. These factors have been shown to increase the likelihood of value creation in acquisitions.

The subject of this two year Master's thesis in Library and Information Science is the information practices of illiterate immigrants in everyday life. The purpose is to examine how immigrants seek, identify, understand and value information sources and information, and how the practices have changed with their arrival in Sweden. It furthermore focuses on the barriers that illiterate immigrants meet in accessing and understanding information. It moreover investigates the strategies they use to overcome them.For this purpose twelve qualitative research interviews were carried out, with illiterate immigrants as well as with service providers. The theoretical concepts of the essay is information practices, which means that the information process is within a context, and information poverty, that people in different context do not have adequate and equal access to information and information sources.Using McKenzie's model of information practices, the essay concludes that illiterate immigrants are active in their information process, especially when they interact with information.

Under sex veckor har jag jobbat på Stillfront AB och varit delaktig i skapandet av ett webbaserat vilda västern spel, den här rapporten kommer handla om min tid på företaget. Uppsatsen är framförallt en undersökning om hur man skapar en karaktär för ett webbaserat spel, men fokus kommer också finnas på mindre arbetsuppgifter och hur det är att jobba i projektform på ett mindre företag..

In this essay, a search strategy for citation index is studied. The strategy, which is essentially a citation cycle, starts with documents retrieved by a subject search, wherefrom new documents are identified following the network of citations backwards and forwards in time. Based on the theory of polyrepresentation, the strategy exploits overlaps between cognitively different interpretations of the same documents in order to automatically select references seed documents used as a starting point for the forward chaining. The purpose of the investigation is to evaluate the retrieval effectiveness of the search strategy and to find out whether the strategy can be used to expand a subject search with the help of the network of references in order to retrieve new relevant documents. Two questions are formulated: 1a.
