    Survey of companies internal security2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This survey aimed to examine and analyze six companies' internal security. Six interviews were held with different sized companies, where the size of the office ranged from under ten to around 800 employees. The interviews contained questions regarding their information security, their perimeter security as well as the employees' personal security. The larger companies had more policies and security procedures than the smaller companies. Virus protection, banning USB flash drives from outside the company, security education and a well functioning report system are vital for a satisfying internal security.

    Interviewees from the smaller companies saw internal security principles as a necessity but also as an obstacle. The larger companies saw the same principles as something that would improve their security. These companies also had implemented more safety measures both in software, such as remote controls and guidelines for employees. Targeting problem areas with special educational campaigns helps employees defend themselves against social engineering.

    All companies that participated either develops software or are consultant companies in IT. They deliver IT solutions in one way or another and their internal security should reflect the same high standard and IT maturity. The smaller companies did not perform any risk analyses on which threats their company faces and did not have any safeguards in place if their employees do not conduct themselves correctly on their networks. Our opinion is that this should not be limited by the size of a company and all companies should perform risk analyses to be able to improve their internal security in the future.

    Investigating the impact on subjective satisfaction and learnability when adopting cloud in an SME2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Cloud services and solutions have served as a shift in the computer industry and create new opportunities for users. Clouds have been described as easily usable and fluid in terms of expansion and contraction depending on the real-time needs. Although the cloud is promoted with several benefits, it is not always apparent for the users that this is the case. Understanding both the benefits and challenges that exist is substantial for a successful adoption to cloud. This master’s thesis is conducted in collaboration with Exsitec ABand aims to investigate how the adoption of the cloud service Microsoft Azure will affect the development process. Also, it aims to provide a best practice for potentially needed updated working procedures, in terms of satisfaction and learnability. The investigation was performed through interviews and the System Usability Scale, to assess how the end users experienced development in a cloud environment. The thesis revealed that the Azure portal has low overall usability, but that there also exists an inconsistency of that perception. Two major factors that contributed to the satisfaction and learnability was the lack of documentation and that the Azure portal was considered hard to master. The SUS score revealed that the mean value was below an acceptable level, and thus changes in the company’s working procedures need to be implemented. Internal documentation regarding how the company should use both cloud in general, as well as the portal in particular, are required in order to increase the learnability and subjective satisfaction.
