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.

The purpose of this study has been to investigate how psychosocial support for families where a parent suffers from a life threatening illness can be constructed. The intent was also to explore how the child's perspective is protected and what barriers and opportunities there are for family oriented support. The study has a qualitative approach and includes interviews with four social workers. The interviews were analyzed with a systems theory and attachment theory. The conclusions are that the whole family suffers psychological and social pressures when a parent is sick.

This paper examines and compares several different sites in Sweden in addition to one in Mexico regarding whether the ecological requirements theses sites have had during planning and construction has affected the design in any way. Is it possible that, for different reasons, one thinks ?like nature? when one thinks of ecology and, if true, how does this reflect on the spatial and structural design? This paper tries to identify if some sort of general design expression is used in projects with requirements on ecological sustainability. In total, five projects have been compared in different areas such as choice of materials and their composition. These projects have an ecologically sustainable processing of water in common, although most also have ecological consideration in other areas as well.

The purpose with our essay was to increase our knowledge about what social workers, with experience from working with drug addicts, perceive as the explanations to a person stopping the abuse and succeed in staying drug free. Our framing of the question was:- How do social workers define the term drug free?- How big a roll do the social worker believes she/he has in the process in which a person stops abusing drugs?- How do the social worker work with a person towards getting that person drug free?- What do the social worker believe to be the reason why a person stops abusing drugs?- What do the social worker perceive as helpful for a person to stay drug free?We did qualitative interviews with six social workers. Our main conclusion was that it is difficult to define the term drug free. The reason for stropping the drug abuse can vary, it can be the family situation, "hitting rock bottom", finding love or tiring.

Internet is growing every day and this is leading to an address depletion of the current IPv4 addresses. A new version of IPv4, called IPv6, is the protocol for addressing computers that will deal with this problem. IPv4 and IPv6 are unfortunately not compatible with each other. IPv4 and IPv6 have to co-exist for a long time until IPv6 will be the dominant protocol.The purpose of this thesis is to examine how a transition could be done or more correctly, how to deploy IPv6 in an already existing IPv4 network. After that part of the report a case study at the local Internet service provider Junet AB will be conducted.

The connection between rune stones and churches is a known phenomenon. Unfortunately, very little is known about the previous function of the church sites, and consequently very little is known about what the connection between rune stones and churches means. The purpose of this study is to examine the rune stones connected to churches in the administrative province of Jönköping, in an effort to ascertain their purpose, symbolism and function. The aim is to find out if the rune stones connected to churches were primarily or secondarily placed on the site where the church was later built, and why some rune stones were built into the churches. Further, the inscriptions and iconography of rune stones have been analysed, and also their relation to their immediate surroundings.

The residential area Pennygången in Gothenburg is planned to be restored in a very expensiveway. As a consequence the rents will increase dramatically and about 80% of the peopleliving there today will have to move. Excisting social networks might be disrupted.The aim of this project is to illustrate a part of the present social network at Pennygången inthe form of a photobook.I have photographed 12 families in their homes. These families know each other in 36different ways. The final photobook illustrates all these friendships by presenting the familiesknowing each other in pairs..

The purpose of this study is to increase the understanding of how venture capitalists can use their network in order to reduce information asymmetries between themselves and the venture management team. A qualitative approach with semi-structured interviews, consisting of open questions, have been used to receive gradate information in order to reach our explorative purpose. Our theoretical framework consists of relevant studies made on the dynamics of networks and the problems that can arise in the complex relationship between a principal and an agent. We have been interviewing two venture capital firms and therepresentatives from two business angel networks. We also made an additional interview with an influential financial actor in order to try to verify our conclusions Our conclusions are that an extensive network can be used by venture capitalists in order to; verify ventures? technologies, complement the competences in the venture management team, and arrange co-investments, resulting in reduced information asymmetries between themselves and the venture management team.

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..

Outages in the electric grid can be costly for society. Because of this, reliability is one of the parameters used to regulate network companies. Reliability in electrical grids can be measured with SAIDI, system average interruption duration index, which for Fortum Distribution has increased in Stockholm?s distribution network (11 kV) in the early 2000?s.By using outage data for Stockholm from 2011-2013, sets of parameters to be used for reliability calculations in the network information program Tekla NIS were derived. Two different options for investment were then analysed: changing old cables with high fault frequencies, and installing automatic switching in distribution substations.

Thesis purpose: The purpose of this master thesis is to investigate the expectations of roles between supplier sales representatives and retailer store personnel in relation to in-store campaigns, this in order to enhance effectiveness of these functions creating an increase in consumer response. Methodology: The researchers believe that social phenomenon and their meanings are continually being accomplished by social actors, hence a study of individuals? expectations must have a point of departure in these people?s social reality. Store personnel and supplier sales representatives are to a certain degree affected by the structural power relationships within the organizational network, thus the researchers combine an interpretative and radical structuralist paradigm. Theoretical perspective: The researchers investigate expectations of roles through examining interaction between parties involved.

This paper deals with the early mesolithic sites in Gladö, a part of Hanveden situated south of Stockholm. It tries to explain the big amount of sites, why people came to these islands and what they were doing there. The large shore displacement together with the topography of the mesolithic islands resulted in a rapid change of suitible areas for camping. The prime occupation was sealhunting on the ice of the Ancylus lake in early spring. As the archipelago became larger other activities as fishing and birdhunting got more important and people stayed for longer periods..

This master thesis has been carried out on behalf of Stoneridge Electronics AB and is an investigation ofhow intelligent switches can replace the traditionally used direct controlled switches. The concept ofintelligent switches is that the switches contain electronic identification components which, by connectingthem to a network, give the same function independent of the location of the switch. This infers anincreased flexibility and configurability which can be a great advantage in development, production andcustomization in the commercial vehicle industry. Especially in the current situation when commercialvehicle manufacturers provides more and more functions and dashboard configurations.LIN (Local Interconnect Network) is a network protocol introduced in 1999. It is a simpler and lower costcomplement to CAN (Controller Area Network) and is adapted for applications where the demands forbandwidth are lower, for example reading sensors and switchers.

Hemmasittare is a new term for children and youths with a history of long term truancy. As the term indicates these youths spend most of their time in their homes. This often results in them being socially alienated and the loss of their earlier social network. The consequences of hemmasittande and social alienation are many and include not only a deficient social network but also psychological and physical problems. Research has shown that many of these problems follow on through into adult life.
