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 purpose of this study is to examine which security approach dominates Sweden?s strategy for combating human trafficking. The two approaches covered in this essay are the state- centred perspective, and the individual-centred perspective. These approaches are being used because those two approaches are on each end of the security spectrum, and it is important to discover from what approach Sweden is working. This is important because it might help us to get a bigger understanding on why certain policies are being made.

This master?s thesis investigates the technology and security awareness associated with wireless networks (WLAN). It has been stated by the media and theories that many wireless networks are unprotected. This has sparked an interest to investigate the phenomenon in the Jonkoping region. The study is based on the following research questions:- What security weaknesses are present with the WLAN-technology and how can these be avoided?- How does the wireless infrastructure in the Jonkoping region look like?- Why do companies implement the WLAN-technology?- Are the companies aware of the risks involved with WLAN?We conducted this study in three steps; the first step was to hack a wireless network in a controlled environment in order to investigate the weaknesses of the commonly used security measures.

The use of Web applications is a growing area. While the possibilities and functionalities are increasing, so is the complexity of them, together with the threats against them because the complexity also opens up the application to vulnerabilities. It is therefore important for developers to know how a web application can be developed with security in mind.This study?s intention has been to create an introductory documentation of what kind of techniques that exists which can produce higher security, which methods there can be within the development process and what to think about when programming secure web applications. In this paper we have investigated how theoretical manuals in the IT security department handles that area, and interviewed two developers from two different companies to see how they use security in their web applications.The study has an exploratory technical perspective and does not explain how to practically use and interconnecting different security-enhancing technologies, but is more suppose to give a first glance at what is available and sow a seed for those interested to continue reading further about the subject.

The purpose of this study was to examine and explain Sweden?s defence and security policy during the twenty-first century. The method that was used in this research was a case study. The material that was used were government documents focusing on this area of policy, and numerous books concerning the theoretical perspectives on international relations and defence security policy. The study is of an explaining art and the analysis explains Sweden?s security and defence policy during the twenty-first century. The analysis explains this by testing it against a liberal and a realist view on international relations. The conclusion of the study is that Sweden?s defence and security policy has been liberal during this time period ? and still is.

Voice over IP (VoIP) is a relatively new technology that enables voice calls over data networks.With VoIP it is possible to lower expenses, and increase functionality and flexibility. FromSwedish Armed Forces point of view, the security issue is of great importance, why the focus inthis report is on the security aspect of the two most common open-source VoIP-protocols H.323and SIP, some of the most common attacks, and counter-measures for those attacks.Because of the level of complexity with a network running H.323 or SIP, and the fact that it hasyet to stand the same level of trial as of traditional telephony, a VoIP-system includes manyknown security-issues, and probably at present many unknown security flaws.The conclusion is that it takes great knowledge and insight about a VoIP-network based onH.323 or SIP to make the network satisfyingly safe as it is today, and is therefore perhaps not asuitable solution for the Swedish Armed Forces today for their more sensitive communications..

The e-commerce in Sweden has increased each year for the past several years, but still just over half of all the consumers feels worry about payment security. This could be the reason why over half of the consumers just shopped about one time on the Internet during the whole year of 2009. Another reason could be that the many consumers have a lack of trust to the different payment methods that are available during payment on the Internet, because they might don't possess enough knowledge regarding the payment methods and their security. If the consumers were to gain more knowledge about the payment methods and their security, it may lead to that the they would feel more comfortable when shopping online, and do it more frequently. It is this that will be investigated in this paper.The purpose of the paper  is to research if consumers believed knowledge concerning the different payment methods available on the web and their security influence the consumers trust in the payment methods.

In the world after the Cold War, internal and ethnic conflicts have been predominant. Ethnic conflicts have their own theories on why they erupt and what can be done to solve them. This essay seeks to analyze how the Ethnic Security Dilemma can explain the causes, and possible solutions, of today´s armed ethnic conflicts.By making an ideal types typology over different types of ethnic conflicts, and then analyzing the Ethnic Security Dilemma´s impact on each conflict type.

Smartphones have become more common as business tools within the workplace. With its many features and great flexibility, the smartphone has stormed the business world and become an alternative or complement to the laptop. As these mobile units' popularity has increased, the interest of businesses to invest in this new technology has increased, but has security kept up with the technology developments?This study aims to conduct a study to see if the companies in the IT industry have the same safety awareness for smart phones to laptops.The study shows that companies have greater safety awareness and higher safety requirements for laptops than smartphones. Meanwhile, both end-users and management are well aware of the risks and threats that the smartphone is facing..

Background: Risk Management plays an important part of the enterprises strategic business activity.

Corporations have realized the importance of the information which is stored in the IT systems. IT is the tool for businesses future progress and growth and therefore a source of risks.

The terror attack in New York year 2001 was a turning point in international politics. New policies were reformed in both USA and EU to secure their citizens from terrorism. The power of the institutions has developed and the question is; how does the new security policy affect people?s freedom? Is it the agencies new policies that are restricting the freedom or the actions of a terrorist? The purpose of this study is to examine if the security policies in USA and EU are protecting their citizen?s freedom. Many individuals are not aware of how much the security policies are affecting their lives.

Information security is an essential part of all information systems; especially in large organizations and companies dealing with classified material. Every large information system has an architecture that includes many parts that together form an Enterprise Architecture. The aim of this thesis is to study how to describe several security functions in an Enterprise Architecture and also how to ensure accountability between requirements and the implementation of the security functions. The description is for stakeholders on a conceptual level rather than a technical level. The study has been carried out by comparing the theoretical framework that has been formed by a study of the literature, and the empirical framework that has been formed by a group discussion and interviews with Information Security Consultants from Combitech AB.
