Existing cybersecurity analyses and frameworks offer a set of guidelines for preparedness and security countermeasures against cyberthreats. However, there is little knowledge on the perceived value of these. This thesis explores the value of common cybersecurity analyses and frameworks, to understand their values for the organizations looking for a holistic overview of the possible countermeasures against cyberattacks. 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…
A User-centered system with blockchain in the Norwegian healthcare: From a security and privacy perspective
2021
Master's thesis in Cyber security (IS507) With the current Covid-19 pandemic roaming the world, the IT attacks on the healthcare sector has increased five folds from 2019 to 2020. The Norwegian healthcare system is divided into different regions with their own systems respectfully. 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…
Norwegian cybersecurity guidelines : A case study of Norwegian security agencies
2021
Master's thesis in Cyber security (IS507) In recent years, several countries in Europe have focused on developing their own national solutions for cybersecurity. Norwegian security authorities have also developed national guidelines to develop a common national solution to meet the ever-increasing focus on Euro-pean and international regulations within cybersecurity. The study sheds light on elements related to the issue at both a national and international level and seeks to discover how national cybersecurity guidelines can emerge in the cyber landscape in the coming years. The study was carried out as a qualitative method using a case study in Norwegian security authorities. In addition,…
Investigating Cybersecurity Awareness in SME Organisations
2021
Master's thesis in Cyber security (IS507) Cyberattack incidents against small to medium-sized enterprises (SMEs) increase nowadays, thus cybersecurity awareness is becoming an important issue to enhance the security of the SME organisations. However, despite the importance of cybersecurity awareness in many organisations including SMEs, such awareness is not yet fully absorbed as day-to-day practice in organisations.In this study, we have investigated cybersecurity awareness in small to medium-sized organisations (SMEs) in Norway. The purpose of this study is to provide knowledge, empirical data and relevant literature about cybersecurity awareness for SMEs that operate with security protoc…
Otnetic: A Cyber Range Training Platform Developed for the Norwegian Energy Sector
2021
Master's thesis in Cyber security (IS507) As cyber attacks have become increasingly frequent and complex, the need for effective cyber security training has become essential. This master thesis was developed in collaboration with the client organization NC-Spectrum, with the objective of developing an alternative training program utilizing cyber ranges and gamified training for OT-personnel in the Nor-wegian energy sector. The need additional training was identified by the client organization initially, and reinforced through the findings from the literature review and interviews conducted as part of this thesis. Current training methods commonly use one-way communication, which has been sh…
Resilience in Critical infrastructure within the energy sector of Norway
2021
Master's thesis in Cyber security (IS507) This thesis investigates what are the characteristics of resilience within the energy sector, as well as what are the "best” known practices being used to increase awareness of the employees. By looking at the existing literature and finding differences between how the energy sector in Norway vs other nations approaches resilience. There is a difference in Norway's more decentralized power grid, where many smaller power stations supply energy, compared to other nation with single large power station. This influences how they will approach resilience. The study uses a qualitative research approach, with semi-structured interviews to gather data from …
In situ recordings of large gelatinous spheres from NE Atlantic, and the first genetic confirmation of egg mass of Illex coindetii (Vérany, 1839) (Ce…
2021
AbstractIn total, 90 gelatinous spheres, averaging one meter in diameter, have been recorded from ~ 1985 to 2019 from the NE Atlantic Ocean, including the Mediterranean Sea, using citizen science. More than 50% had a dark streak through center. They were recorded from the surface to ~ 60–70 m depth, mainly neutrally buoyant, in temperatures between 8 and 24°C. Lack of tissue samples has until now, prohibited confirmation of species. However, in 2019 scuba divers secured four tissue samples from the Norwegian coast. In the present study, DNA analysis using COI confirms species identity as the ommastrephid broadtail shortfin squid Illex coindetii (Vérany, 1839); these are the first confirmed …
The expectations and perceived usefulness to a future secure "net-health" portal for patients with chronic diseases
2006
Masteroppgave i informasjons- og kommunikasjonsteknologi 2006 - Høgskolen i Agder, Grimstad The recent advancements in technology are constantly changing the way healthcare is practiced and delivered.

Exploring the Gender Digital Divide in E-Government Use in a Developing Country
2020
This article explores the gender digital divide in e-government use in Turkey. Historical trends and differences in internet and e-government use by males and females are investigated. The findings of this study indicate that although internet use has increased over the years, there remains a steady and significant gap between males and females in terms of internet use and e-government services use. It appears that females in Turkey tend to be on the wrong side of the digital divide, and a significant number of females do not benefit from the potential advantages of the internet and e-government services. The gender digital gap in e-government use is higher than in internet use.
