Firewalls protect network traffic and decide witch traffic to send further and witch traffic will be blocked. All this depends on the rules in the firewall. The firewall is installed between the internal network and the Internet. It is difficult to find a firewall that can protect us against different threats. Firewalls have both advantages and disadvantages and all this make them vulnerable.

The purpose of this thesis is to examine value creation in networks. Based on a case study of Livebookings Network, an online booking service. This thesis has an explorative nature. As a theoretical framework we use theories on value and network dynamics. By combining these theories we develop an operationalized framework that we use to analyze our empirical findings.

The departure point of this thesis is the context of the institution and the processes surrounding the handling of personal archives at the National Library of Sweden. These processes are examined using Actor Network Theory. Around the personal archive a network is constructed and contained by actors ? the archive itself, the librarian, the conservator, the researcher, organizational structures and others. Within this network choices are made of what is significant.

AbstractPeople and organizations that network with one another have during the past decades, at a larger extent than before, replaced classical hierarchies. These networks have become increasingly important, as the globalisation has amplified the pressure for focused and flexibleorganizations. There is a risk of restraining the inventiveness of the firm and force customers and suppliers into cooperation by a too great commitment and dedication to the network. There are two sides to every penny, positive and negative aspects of networking.Concerning the negative approach to networking, there is relatively little theory present. The theory is regarded an emerging theory.

This thesis discusses various approaches that venture capitalists have when evaluating investment prospects. The thesis is a case study of the business angel network Firm Factory Network. The empirical material is based on an extensive interview with Firm Factory CEO Daniel Kaplan. Our conclusion is that Firm Factory Network uses both informal and formal methods when they evaluate interesting prospects..

This examination work is about implementation of Cisco Systems Network Admission Control (NAC) within a leading IT-company in region of Jönköping. NAC is a technique that is used for securing the internal network from the inside. NAC can verify that the client who connects to the network has the latest antivirus updates and latest operative system hotfixes. Clients who don?t meet the criteria can be placed in quarantine VLAN where they only have access to the update servers.

We are living in network society, where information and communication together with the technical development stands in the centre. Characteristic for network society is quick changes, new meaning of time and space, convergence and new possibilities of communication. Network society contains new technical developments, several with thepurpose to improve the possibilities of communication between human beings, which in some ways creates new social demands and expectations. In this study, I focus on the Internet, which is an important channel for the information, communication and marketing in network society. As whole network society, the Internet is constantly developing.This study, implemented with qualitative interviews, has the purpose to give new, deep and interesting knowledge about business to business companies? communication and marketing on the Internet.

The purpose of this master`s thesis is to examine how the contemporary changes in society display itself in the network Ecumenical Forum of European Christian Women EFECW and to increase the understanding of networks. My main questions are: What does the networks structure look like? What does the networks relationships look like? How is identity created in the network and what types of identities is created? The objectives are reached by using two methods, qualitative inquiries and document analysis. The inquiries were carried out to nine members in the network of different countries. The theoretical framework of the thesis is Manuel Castells theories of the network society, and the study is also placed in context by a presentation of previous research on the field.

The purpose of this thesis is to explore the co-creation process and how value is created based on a service orientation using a network perspective. The thesis is studied from a social-constructionist philosophy, using a qualitative approach of data collection and the theoretical framework includes network theories, theories of service-orientation and co-creation. We have conducted semi-structured interviews with a small firm and its network, which consists of a customer, a supplier and a partner. We found that Håkansson?s ARA framework combined with Ballantyne and Varey?s triangulation of value-creating activities help to acquire an understanding of the actors? bonds, the resources? ties and the activity links that exist in a network.

The aim of this report is to examine the possibilities to use network theories to perform vulnerability analysis on complex networks. The scoop of this work is also to improve the possibilities to chart, analyze and present the vulnerability in a power grid. In this report it has been, using power outage statistics, possible to verify, that network theories can be used to evaluate the vulnerability of an infrastructure network. However further studies to establish values on how vulnerable a network is are needed..

In this thesis a rural network in Norrbotten, Sweden, has been to designed and planned with the purpose of improving distribution reliability by exchanging existing overhead lines with underground cables. General network design considerations are discussed as well as the ones for the specific low voltage grid. During the design phase the maximum power of domestic consumers has been estimated using Velander?s method. Currents, voltage drop and impedance of the network have been calculated and fuse operation and selectivity has been considered.

The network with its virtual business structure challenge the established vertical business structure. Part of the network theory that has developed focuses on relationships that forms B2Bnetworks. One way to create a B2B-network is for independent businesses to form a organization promoting co-operation. For co-operation to be successful it requires well thought-out actions, but a lack of how these actions are implemented have been noticed. This study explores how encouragement of co-operation can be done practically.

Energy losses are an essential part of a power grid company?s costs. From anenvironmental and economic perspective, it is important to reduce these costs. Toknow where efforts should be deployed, it is important to have good knowledge ofwhere in the network losses are situated. When creating network tariffs, there is alsonecessary to have a correct distribution such that the network customers that use acertain part of the network, only pays for the network losses in this area.
