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.

Den här rapporten beskriver en experimentell studie av Microsoft Network Protection (NAP) och är ämnad för att utvärdera hur mogen tekniken är för att implementeras i en aktiv nätverksmiljö. För att göra studien tog vi hjälp av gymnasieskolan John Bauer i Kalmar. Tester har utförts med DHCP-framtvingning och 802. 1x-framtvingning, dessa är två av NAPs fyra olika framtvingande funktioner. En mindre analys av skolans switchkonfigurationer och interna säkerhet har även gjorts på John Bauers begäran.

The aim of this study has been to examine the role of control mechanisms when it comes to building relationships in a small business network. In order to reach this goal, we have performed a case study of a Swedish supplier of machines to the engineering industry, which acts as the exclusive representative of a foreign manufacturer on the Swedish market. Main results: A number of control mechanisms, both formal and informal, could be identified in the network. Their specific use, as well as relative importance differ between different actors in the network. In general, the importance of formal control mechanisms decreases as the relationship evolves over time and the importance of informal ones, mainly trust, increases in a corresponding manner..

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

Auditing demands knowledge in many diverse areas. To be able to provide all this knowledge it is necessary for the auditor to have access to persons with special skills. Through these contacts the auditor builds up a business network that brings support in the daily work. Our purpose with this study is to find out how auditor?s network in big auditing firms is organized and to show how they use their network.

To have a tool that guides you when you work with a complex system can be helpful since the complexity of the work can be reduced. In this thesis I explore the possibilities to use a helper application whilst planning installations of access control systems. The purpose of the application is to provide support during the planning and at the same time make the user aware of the limitations that exist in the access control system ARX Access. By combining early user input and the theory of formativity, the result became an application written in Java..

When contemplating entering an alliance the rationale behind the decision should differ depending on the size of the companies involved as well as on other important factors. The important factors influencing the decision are related to the resource pooling potential of the alliance, the power structure along with the business network the companies are a part of. The analysis has shown proof of a need for cooperation if one wish to succeed in the telecommunication industry and it has also determined which resources that are deemed to be most important to get in touch with, for our study object, to facilitate its access to the market. Those resources are defined as a direct channel to the customer, funds/capital and the access to relevant business networks. To get in touch with these lacking resources, three alternative approaches has been proposed; all of them involving a strategic alliance decision.

This paper describes a case study of the largest film production ever conducted in Scandinavia. The study aims at explaining the complex relationships in the network structure in which the project took place. Coordination of creative projects carried out in a network context, includes handling conflicting interest and contradictions. Creativity needs space and freedom while projects need structure and coordination, whereby controlling these projects becomes complex. Adding to the complexity, does the loose form of organization that the network structure represents, without any long term structure.

Since the 1990?s Open Access has developed into an alternative model for scientific publication. Today an increasing political interest in promoting Open Access is commonly channeled through the implementation of policies by research funders. However, in the scientific community the uptake and acceptance of the model has been of notably different character.This Master?s thesis examines the understanding of and attitudes towards open access among eight senior Swedish researchers and how these have been affected by the implementation of the Swedish Research Council?s Open Access-policy as implemented in 2010.

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.

The following thesis concerns the conceptualization of openness within the open access movement. Open accesscan be understood as a phenomenon or a movement that aims at changing the current system of scholarly communication.Consequentially, the movements goals arose in relation to the escalating serials crisis in scholarly communicationand the increasing power of commercial publishers. The purpose of the thesis is to study three centralopen access declarations with the aim of uncovering the different conceptualizations of openness found withinthese texts. Leaning on the theoretical position known as actor-network theory, the declarations role within a surroundingnetwork is explored by focusing on how openness as a concept has been produced and reproduced bycentral actors. Two overarching questions frames the study: How is openness conceptualized within the declarations?And how can openness, as a concept, be understood as an effect generated by a larger network?The first part of the study focuses on the first question.

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.
