Allmänhetens säkerhetsmedvetenhet med avseende på trådlös kommunikation
Offentliga trådlösa nätverk finns idag mer tillgängliga än någonsin. Samtidigt haralla dessa nätverk något gemensamt ? de går alla att avlyssna och risken finns attanvändarens information kan komma i fel händer. Uppsatsen behandlarallmänhetens säkerhetsmedvetenhet med avseende på denna typ av nätverk genomtvå undersökningar. Den första undersökningen sker via ett tekniskt experiment därdet på flera geografiska platser har erbjudits ett trådlöst nätverk till allmänheten.
Människan och lärarprofessionen : En livsberättelse
The aim of this essay is to get a deeper understanding of a teachers' profession and to get knowledge of how earlier experiences can influence you as a teacher. I have interviewed a female teacher, Pia to get this understanding. As a tool to get the teacher's whole story I used the life story method. In her profession she is influenced by her own importance of security as a child.Her own needs of security has given her an deeper understanding for pupils like herself during the childhood; insecure and afraid. Her understanding for all kinds of behavior among the children has increased by her own experiences.The story shows that Pia is frustrated by the fact that she can't control her own working time.
Koncern som tillväxtinkubator för småföretag : ? En fallstudie i ett shared service centers möjligheter attstödja entreprenöriella småföretag
???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.
Veto: En motivanalys av FN:s säkerhetsråds fem permanenta medlemmars agerande i konflikten i Syrien.
Aim: The aim of this study is to analyse the possible motives behind the actions of the five permanent members of the UN Security Council in relation to the conflict in Syria. The background of this aim is the Arab Spring and the protests and violence that have followed the uprising. While, in Libya, the UN Security Council adopted resolutions that allowed sanctions against the Libyan government, no such resolutions have been adopted yet in Syria.Theory: The principal theory of the analysis is Stephen D. Krasner´s theory on sovereignty.Method: I have researched various resolutions and statements done in the Security Council, together with official statements from the actors, through Hadenius´ motive analysis methodology and Gilje & Grimen and Ödmans theories on hermeneutics.Conclusion: The conclusion of the analysis is that there, in the case of Syria and Libya, are two different parties in the Security Council. One that stands for sovereignty and one that stands for intervention.
Att tyda tecknen -En alternativ syn på förändringarna av Japans säkerhetspolitik
Japan's foreign and security policy has seen some substantial changes as a result of events like the first Gulf war and 9/11th. This has been taken as proof, by some, that Japan is abandoning its antimilitaristic stance and pursuing a more traditional hard power role through military means. This essay aims to explore if these shifts have coincided with any substantial shifts away from antimilitarism, which has had a strong influence on the country's security policy since the end of WW2.To do this I use constructivist theory, specifically regarding the impact of norms and identities on states security policy and briefly look into the problem of actor designation. The thematic focus is on security policy, from a narrow perspective, and thus I examine areas like the input and output to the Japanese military and the actual applications of this force. State identity is used to explore the prevalence of nationalistic sentiments and support for anti militarism in the public opinion and the political elite.The result of this study points to the further relevance of constructivist theory and especially the application of norms and identity.
Trådlösa Nätverk : säkerhet och GPU
Trådlosa nätverk är av naturen sårbara for avlyssning för att kommunikationen sker med radiovagor. Därfor skyddas trådlosa nätverk med kryptering. WEP var den första krypteringsstandarden som användes av en bredare publik som senare visade sig innehålla flera sårbarheter. Följden blev att krypteringen kunde förbigås på ett par minuter. Därför utvecklades WPA som ett svar till sårbarheterna i WEP.
ISIT-modellen : Vägledning för att realisera en verksamhets informationssäkerhetsmål
The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to realize their information security goals. In spite of this standard, studies show flaws regarding information security in organizations. In particular flaws regarding overall view, knowledge and clear roles and responsibilities have been observed. The ISIT (Information Security Integrated Three level) model and its guidelines, developed in this thesis, help organizations to identify the required processes and procedures as well as the logical process flow. The thesis is based on theoretical studies and a case study within a multinational company.
Design och implementering av enhandsburen RFID-läsare
Radio frequency identification (RFID) is a versatile wireless technology usedworldwide. The fields of applications are many and its popularity constantlygrows due to smaller in size, better and less expensive components. RFID isused to identify, track or share information about an object using radio waves.This master thesis describes the process of designing and implementing ahandheld UHF RFID reader. The goal was to, based on a UHF RFID-chipdesign a fully functional, small in size and power efficient device. Amicrocontroller provides the user interface and is also used to control theRFID-chip and a Bluetooth device.
Business Potential of Software Defined Radio Technology
The business potential of software defined radio (SDR) technology is studied by evaluating whether or not its characteristics correspond to those particular to a disruptive technology. The maturity of the SDR technology concept is illuminated by analyzing the opinions and perspectives of a selection of representatives for different stakeholders in the wireless communications market. Characteristics as, for example, the degree of consensus about the utility of SDR technology and the awareness of features and limitations are studied by application of the theory of technological frames. This theory helps us understand how and when technology evolution takes place. Finally we describe the value network structures of some potentially viable application areas for SDR and suggest some possible business opportunities based on SDR technology.This thesis is carried out as a case study and the research data is obtained from secondary sources, such as literature and Internet publications as well as interviews with people well experienced in the field of wireless communications.
Förväntningar på Framtida Mobila Tjänster
Today?s society is very focused around technology and something that is very popular is the usage of mobile devices such as Smartphones or Tablet computers. One of the reasons why these devices are so popular, is because of the large amounts of services or ?apps? that they can provide for the user. They can do a lot of things that makes everyday living easier for the users.The focus of this study is to find out what kinds of mobile services the users of these devices are expecting and/or wishes to see in the future and what is required to be able to develop and use these services in a good way.We started of the study by searching for earlier studies on the same or similar subjects.
Staters förhållningssätt till Human Security i teori och praktik : En jämförande fallstudie om kriterierna för verkställighetshinder till Syrien hos Sveriges och Norges migrationsverk
Den här uppsatsen handlar om staters förhållningssätt till human security i teori och praktik. Syftet med uppsatsen har varit att undersöka om den kanadensiska definitionen av human security används som referensobjekt i policydokument från Norges och Sveriges nuvarande regeringar samt hos ländernas kriterier för verkställighetshinder av syriska medborgare. Uppsatsens metod är en jämförande fallstudie där verkställighetshinder och utvalda policydokument utgör analysenheterna. För att analysera dokument och ställningstaganden används kvalitativ textanalys.Fallstudien visar att båda länderna ser sig själva som föregångsländer inom human security, bland annat genom skapandet av strategier och handlingsplaner. Vidare visar studien att migrationsverken har olika tillvägagångsätt för verkställighetshinder till Syrien.
Trådlösa nätverk, säkerhet och kryptering
Användandet av trådlösa nätverk breder ut sig mer och mer både bland företag och privatpersoner. För privatpersoner kan det vara skönt att slippa sladdarna som ett vanligt nätverk för med sig och för företag kan det trådlösa nätverket fungera som ett komplement till det vanliga i miljöer där man inte kan eller vill använda vanliga nätverk. Det är ett smidigt sätt att koppla upp sig mot ett nätverk utan att vara fysiskt ansluten till det. Smidigheten har dock ett pris i form av att det är lättare att avlyssna trådlösa nätverk i och med att kommunikationen går genom etern och det saknas fysiskt skydd i form av byggnader och lås som finns för traditionella nätverk. Med tanke på detta är det viktigt att man säkrar nätverket på ett ordentligt sätt.
I detta arbete har jag studerat trådlösa nätverk; hur de fungerar, vilka hot som kan finnas och vad man kan göra för att skydda sig.
Vikten av säkra nätverk
The purpose of this thesis is to show how to use vulnerability testing to identify and search for security flaws in networks of computers. The goal is partly to give a casual description of different types of methods of vulnerability testing and partly to present the method and results from a vulnerability test. A document containing the results of the vulnerability test will be handed over and a solution to the found high risk vulnerabilities. The goal is also to carry out and present this work as a form of a scholarly work.The problem was to show how to perform vulnerability tests and identify vulnerabilities in the organization's network and systems. Programs would be run under controlled circumstances in a way that they did not burden the network.
Kampen om ett föränderligt Arktis : En jämförande studie av Rysslands och Kanadas agerande i Arktis och Arktiska rådet.
The Arctic region is rich in natural resources such as oil, gas, minerals and fish. Climate change causes the Arctic ice melt, making resource extraction possible as well as opening up new transport routes through the Northwest Passage and the Northeast Passage. This has led to competition and cross-border strife among the Arctic States. The two largest states in the Arctic are Russia and Canada, which are also members of the Arctic Council. Russia and Canada are at the moment involved in several disputes regarding the Arctic territory where the ownership of the North Pole is one example.
