International organizations are important actors on the stage of world politics, and how these actors securitize the climate change issue is of importance for how it will be tackled by actors on global and national levels. The purpose of this study is to contribute to research on climate security discourses and how climate change is defined as a security concern amongst different actors. This study, in contrast to previous research, focuses on systematically mapping the definitions made by different international organizations by asking: whose security is at stake; who is responsible for responding to the threat; how is the nature of the threat defined; and what responses are suggested? By analyzing material consisting of a variety of documents and statements from five international organizations, I aim to identify differences between these actors ? in how the climate change issue is conceptualized from a security perspective. The result of the study shows that only one of the organizations shows clear elements of the national/geopolitical security discourse, while all of the other actors primarily use the human security discourse.

ABSTRACT The main purpose of IT security policies is to protect companies against intrusion and unwanted spread of information. Statistics show that IT related crimes tend to increase and because of that it is important, from the company?s side of view, to be well prepared. The IT security policy is an important part of that preparation. A lot of the crimes related to IT can be deduced indirectly to employees at the companies where the crime takes place.

The concept of national security has been a matter for debate during recent years, especially in academic fields. Criticism has surfaced since the end of the cold war, directed towards the traditional perspective's dogmatic focus on armed threats and interstate war. Questions concerning an oncoming paradigm shift have been raised, regarding a widening of the security agenda among national states to also include alternative threats, such as environmental hazards. In this thesis, the focus lies on the effects that climate changes have caused in the Swedish national security agenda during the last 15 years. Swedish policy documents show that there have been some major changes, not only the widening of the security agenda but the entire security domain seems to have changed.

This essay conducts a descriptive analysis of the ideas expressed by NATO´s official security strategy "Strategic Concept" from 2010 and the European Union?s security strategy "A Secure Europe in a Better World" from 2003. The purpose of this analysis is to examine whether the ESDP and NATO are compatible with each other when it comes to the role of security policy actor. To do so, I´ve chosen to analyse the actors' security strategies based on three dimensions. These dimensions are: Their view of the international scene, their views on cooperation and their views on how to reach security.

The emphasize of this study is to evaluate security issues for home users having a personal computer connected to the Internet. It focus on the usage of advantages and disadvantages when using a firewall while connected to the Internet. The hypothesis is that it gives a better protection to install and use a firewall compared not to do so, due to security flaws in the operating system. The prediction was tested on a home user's personal computer. The testwork was divided into two major tests, each of them performed with, respectively without, a firewall.

AbstractThe thesis investigates how the European Union promotes stability and security in the Mediterranean region. The aim is to analyse the European Union?s security ambitions with Euro-Mediterranean Partnership, the Barcelona Process. An analytical framework with five sectors (military, political, economic, environmental and societal), based on the Copenhagen School?s theories about security sectors and securitization, is used for the analysis.

The theory of ?security communities? is generally understood as ?dependable expectations of peaceful change? between groups and whether or not the African Union can be said to meet that criteria has been contested in the research community. One of the central disagreements lie in the nature of the region?s conflicts, of which a majority are intrastate but with tendencies of transnational involvement. This paper seeks to understand how extensive this involvement is and how it affects the possibility of classifying the African Union as a security community.

In the post Cold-War era, world politics was transforming itself through its emerging complex issues such as terrorism and influential and interdependent actors such as the European Union. In this new era, the European Union was developing its Common Foreign and Security Policy pillar both to present a coherent and unified EU policy and to prove its political potent in order to become an influential actor on world politics. On the other side, security environment was also transforming its content through emerging actors and issues. As one of the most prominent actors of the world politics, the EU was influenced by the transformation of security environment, whose economic ?soft power? proved necessary but insufficient for being a global power in this emerging security environment.

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.

This paper focuses on the Swedish migration discourse and investigates if and to what extent it is dominated by a security perspective. Analysing a number of official texts and documents I want to show how the discourse describes migrants and what implications this carries with it for the migrants and for the Swedish migration politics. Through discourse analysis I have analysed whose security that is prioritised, the Swedish or the refugees, who is the refugee and the asylum seeker, and who is the illegal migrant in the Swedish official migration discourse. As a theoretical frame for the analysis I have used theories on migration and security. These include theories on the securitisation of politics, the globalisation and the creation of political identity from the nation state perspective and theories on the connection between migration and security.My results show that a security discourse is dominating the Swedish official migration discourse and is therefore defining our reality and the identities of refugees, asylum seekers and illegal migrants.

Business and organizations use computer network in a greater extension than ever before, especially for business-critical use. That increase the demand of security for all systems, both against internal and external threats. The demand on the authentication method used today increases. Today they normally uses password or some kind of smart card. I will performa literature study that will investigate the possibility to increase the security in authentication of users without the use of extra hardware.

The systems environments of today are often distributed and heterogeneous. These kind of systems have several advantages but also disadvantages. One problem is how to keep them secure.The security problems in these environments are mainly due to the communication between the connected computers. It is relatively easy to tap these communication channels from information. There is also a need for the possibility to secure these channels from modification of sent information and to be able to verify the sender and receiver of information in a secure manner.

Container Security Initiative was launched in 2002 by the US Customs and Border Patrol in order to secure the global flow of containers destined for USA. This thesis attempts to analyze Container Security Initiative in relation to a possible future scenario made by the weapons industry where the state's global traderoutes are being subject to militarization. A development which is partly based on the threat posed by global illegal trade. The latter is discussed and defined based on current research made by Carolyn Nordstrom, Moíses Naím and theories on the cosmopolitan perspective made by Ulrich Beck. Strategy documents concerning Container Security Initiative are then analyzed in terms of discourse to try to say something about what the program indicates.

This report presents a method for modelling a computer system from a security perspective. The questions that are going to be treated are:? What defines a secure system and how does the company relate to these factors?? What are the threats today based on hardware/software, human factors and company routines/policies?? What measures should be taken for the organisation to reach a higher level of security for their systems?? How do we develop a method for classification of security and what components should it contain?? What changes are reasonable and necessary with the respect to the company?s resources?The report has been done through interviews and analysis of existing systems on Fla?kt Woods AB. From analysis of material, the aspects judged relevant to the subject and to the company?s needs, have been compiled to a document.

The number of wireless networks has increased rapidly among both home users and companies in just a few years. That has brought a lot of good things with it, for example the possibility to connect wireless equipment to the network or Internet from an arbitrary position within range of the accesspoint. But since the transmissions take place through the air some new security risks appear. It?s difficult to restrict the signals to a specific space and thereby a lot easier for unauthorized to eavesdrop or disturb the signals compared to a traditional wired network.
