Bachelor thesis without a research question I have been asked to provide feedback regarding a paper a friend of mine has written. I sometimes read scientific research in my free time and I am yet to come across anything similar to what that friend has produced. I don't think I can provide any meaningful feedback as I am not sure how to approach this thesis.

This thesis has no defining research question that it is trying to answer. The aforementioned friend of mine wrote his bachelors thesis to merely inform the reader about the subject. As such, no meaningful conclusions were made. The conclusion section of the paper only contains a short summary of previous chapters. That friend of mine studies in Finland. The subject of this paper is Cyber Security. 

Is that friend of mine doing something wrong? If not, could you perhaps point me into the direction of similar research so that I can use that as a baseline to provide feedback?
I can't be sure, but from your description it seems like this thesis does not include original research, and that is what troubles you. Instead of original research, it sounds like your friend may have produced a survey or review of a particular area, which informs the reader about the body of work in that area. (See this answer to Difference between research paper and scientific paper).

A bachelors thesis may or may not be expected to include original research. Your friend should ask his or her thesis advisor to clarify the expectations in their department.
