This report aims to describe the work I have done during my project in company. It is part of my second year in the Master of Computer Engineering – Mobile Computing of the School of Technology and Management of the Polytechnic Institute of Leiria. During this experience, I was assigned two missions. The first one is about the study of a S/MIME solution for email security and the second one is about the improvement of Microsoft Office 365 security score.
For both missions I had material at my disposal and some instructions were given to me. I began by analysing the situation, and then established a state of the art in terms of technologies used. Then, thanks to my knowledge, I simulated virtual computer networks, tested encryption solutions, determined what were the best security practices, automated my work by scripting, reported the difficulties, and provided a detailed documentation about my work.
The solutions produced respond to the problems, and they are functional. For the first mission, client machines can send S/MIME emails in a virtual network. For the second mission, the scripts and the tool provided allow to improve Microsoft Office 365 security score
