Do you think, that when later having some job in IT business it will always be easy?

Speak with your advisor if you can't come up with a suitable subject on your own. Part of the educational process is learning how to explore the domain you are interested in, and choosing a thesis project is part of that. This is not the place to ask this question as the subject matter is pretty much limitless.
