Analys av datakommunikationssäkerhet för VoIP-protokoll
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..
En undersökning i datasäkerhet för hemanvändare - Är det nödvändigt att använda brandvägg?
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. These major tests were divided into five smaller semi
tests. The first semitest without a firewall suffered from a virus or worm
attack resulting in loss of data and log files.
När Arktis isar smälter tinar världen upp? : En kvalitativ analys av det vidgade säkerhetsbegreppet i den svenska strategin för den arktiska regionen
This study is called When the ice of the Arctic melts is the world defrosting? and written by Rebecca Fröling.The purpose of the study is to investigate how the concept ?security? is used in the Swedish arctic strategy and why the concept is described in that way. The debate of the concept ?security? has been going on for years, but the debate is still present today. What we put in to the concept is operative for how we regard and discuss security and security politics.To analyze the strategy I used two theories, one with a traditional approach and one with a critical approach to security: Realism and Copenhagen School.The method that has been applied to the study is qualitative content analysis, to be able to analyze the text on the depth.
Livsmedelssäkerhet, konflikt och hållbar fred - en teoriutvecklande studie om matens makt
In our world, more than two billion people are living under insecure food conditions and more than eight hundred million people are estimated to be starving. The majority of these people live in developing counties which are poor and often subject of civil war. The past fifty years the main subject of security analysis has been the sovereign and rational state and the threats have been viewed in terms of military and weapons of mass destruction. This has come to change over the last decades and security as a concept has broadened, which better represents the reality of today. Within this broader conceptualization of security the main referent of security is the individual, rather than the state, and threats are not only analyzed from a military point of view, but also seen as threats against human rights and freedoms.
Betalningssätt via webben : En studie om konsumenters ansedda kunskap angående olika betalningssätt via webben och deras säkerhet
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.
Human Security in Serbia: A Case Study of the Economic and Personal Security of Internally Displaced Persons
The aim of this study was twofold; firstly it sought to describe the human security situation of Roma IDPs and IDPs living in collective centers, secondly it tried to create an understanding for how the human security situation can affect IDPs capabilities to develop. The findings of the study were mainly based on a field study conducted in Belgrade, Serbia for two months.

Roma IDPs suffer from the same insecurities, but in addition also has poor human security in basic education and personal safety. Their stagnant human security situation proved to be the result of the inability to help IDPs by the actors involved in the relief work.

En känsla av trygghet : Patienters perspektiv inom palliativ vård
Background: Every year 56 million people die around the world and it is estimated that 60% of these people are in need of palliative care. It has been shown that patients in the palliative care experienced their situation as uncertain. When life no longer was certain, the patients tried to live their life day by day and make the best of it.

Therefore patients with a palliative diagnosis could be in need of experiencing feelings of security.
IT-säkerhetspolicy ? efterlevs den av anställda?
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.

Säkerhet till varje pris : En jämförande studie om utvecklingen av privat säkerhet från Kuwaitkriget till Irakkriget
The purpose of this essay is to examine the development of the use of private securitycontractors in Iraq. The reason is that there has been a considerable increase of the number ofprivate security firms operating in Iraq during the last couple of years. The legislation in thefield of private military and security is indistinct and my hypothesis is that the lack of nationaland/or international legislation can be connected to the increased globalization. To come toany conclusions about this I have chosen to make a comparative study between the two casesthe Gulf War and the War in Iraq which started in 2003. In this comparison, I ask thefollowing questions: 1) Are there any signs of anarchy in the field of private security duringthe Gulf War respectively the last War in Iraq? 2) In what way has the use of private securitycontractors changed from Case 1 to Case 2 ?According to my research, there were signs of anarchy in the field of private security bothduring the Gulf War and during the latest war in Iraq.
Privata säkerhetsföretag - Våldet som handelsvara
This essay tries, in different levels, to explain and create a deeper understanding for the phenomena ?private security companies?. By using Mary Kaldors theory about new wars, I will come to the conclusion that the insecurity that these wars create is an important part in understanding the emergence of a security need that these private security companies can provide. Later I investigate and explain howthe neoliberal privatization policy that is spreading through the world today has laid ground for development of the private security industry. When I have answered these questions I analyze how the private security companies can affect the state, war and peace both positively and negatively.
Säkerhetstänkande integrerat i systemdesign via formaliserade metoder
Systems development methods mirror different organizational perspectives, and not all methods are formalised, but what they have in common is the purpose of structuring and supporting systems development processes. Which method would be the most suitable may be determined by the systems development context at hand, because every systems development context is unique. Information is a valuable asset in today?s organizations, and it needs to be protected against both internal and external security threats. In our essay we aspired to find and present suggestions as to how systems developers can include security in the very design based on formalised systems development methods to create systems that are better prepared to meet the security challenges of today.
