Att skydda sin information mot offline-attacker och stöld kan vara önskvärt, därför kan man använda sig utav filsystemskryptering. Den här studien är en prestandatestning av de tre olika kryptoprogrammen BestCrypt, BitLocker och DiskCryptor, som krypterar filsystemet. Resultaten syftar till att ge en fingervisning av vilket kryptoprogram man bör välja. Detta tydliggjordes när testerna visade att filsystemskryptering påverkar responsen hos Apache och FileZilla och att de påverkades olika mycket beroende av kryptoprogram. / To protect data against offline-attacks and theft, which might be desirable, one can encrypt the filesystem. This study is a performance test of the three different encryption programs BestCrypt, BitLocker and DiskCryptor. Results of the study aims to give a pointer to which encryption program one should choose. This was clear when the tests showed that the encryption affected the response of the services Apache and Filezilla and that they were affected differently depending on which encryption program that was used.

Calculations have been a core part of business processes in several industries throughout the years. To streamline the process of calculations, companies seek to digitize their calculation tools to web-based calculation tools. There is currently a lack of studies regarding the performance of web-based calculation tools, and since technology changes occur rapidly, which leads to comparative studies becoming outdated, the availability of actual and relevant research regarding performance comparisons between web-development frameworks becomes imperative. The purpose of this study was to compare ASP.NET with Node.js Express performance-wise, while implemented as web-based calculation tools. The calculations implemented were placed in both the backend and frontend of ASP.NET and Node.js Express. This study consists of experimentation, presenting the experiment results, and analyzing the results to conclude the research questions of this study. The results showed that Node.js Express was the better framework performance-wise and the analysis explains why. This study also concluded that the backend was better performing than the frontend for calculations in ASP.NET, and that the frontend was better performing than the backend for calculations in Node.js Express.
