Måling av effekter av kunnskapssamarbeid : utvikling av et rammeverk for evaluering av interkommunal samhandling
2006
Masteroppgave i informasjonssystemer 2006 - Høgskolen i Agder, Kristiansand Målet vårt med denne masteroppgaven har vært å utvikle et rammeverk for evaluering av IKT-baserte tjenester som støtter samhandling og kompetanseutveksling i forbindelse med interkommunalt samarbeid. Dette dannet grunnlaget for følgende forskningsspørsmål: Hvilke indikatorer fanger opp målsetningene og gevinstene ved IKT-basert kunnskapssamarbeid? For å gjennomføre oppgaven har vi brukt design research som metode. For å danne det teoretiske grunnlaget for oppgaven foretok vi en litteraturgjennomgang av tidligere forskning innenfor de relevante emnene for utviklingen av rammeverket. Rammeverket er basert på DeLone og…
Åpen/fri programvare i norske kommuner : hemmere og fremmere for bruk av Free/Libre/Open-Source Software (FLOSS)
2006
Masteroppgave i informasjonssystemer 2006 - Høgskolen i Agder, Kristiansand Norske kommuners økønomi er stadig mer presset, dette hører vi ofte om i media. Dette fører til et behov for kommunene for å lete etter muligheter for å kunne kutte i utgiftene samtidig som de opprettholder eller forbedrer servicenivåer i forhold til dagens. Dette sammen med et økende fokus fra staten på åpne standarder har ført til at stadig flere norske kommuner vurderer implementasjon av FLOSS. FLOSS er et samlebegrep for Free/Libre/Open-Source Software, til daglig gjerne omtalt som åpen kildekode eller fri programvare. Målsetningen for denne utredningen har vært å klartgjøre hvilke faktorer som virker hemmende o…

A choice made for the study was to mainly focus on IT companies as cases. To address the challenging nature of the thesis topic…
Effective Cyber Security Strategies for IIoT Industrial IoT in the industry sector: Trust and Scalability
2021
Master's thesis in Cyber security (IS507) There has been great growth in the use of IoT. It is a modern technology and is becoming increasingly popular. It is also widely used in industrial sectors where it is referred as Industrial IoT (IIoT). Although the technology can provide great benefits, it also leads to some challenges. In this thesis we will explore the security characteristics of IIoT used in industrial sectors. We will determine why and if there is a correlation between trust and scalability in IIoT infrastructure. In order to do this we will be using qualitative methods for data collection and have performed both interviews and simulations. We also use systematic literature rev…

This fragmentation causes great communication issues between systems and exposes the transmitted data for attacks. To better combat this situation and improve upon the fragmented healthcare systems, a restructure is needed. In this thesis we explore the possibility of using blockchain technology as the foundation of a system that unifies the systems in the Norwegian healthcare sector. We adopt a Design Science Re…
