It can be quite confusing choosing an area to focus on for your M. Sc. IT Dissertation because there are so many areas to choose from. It's one of those things you have to decide for yourself. Choose an area that interests you. A dissertation is supposed to
test your research skills. It usually doesn't have a big impact on your professional life. For my M. Sc. IT Dissertation, I chose to research the security features of
SOAP, but I haven't used SOAP much in my professional life.
