I propose the following research topic: Analysis of the determinants of the development of cybercrime techniques and instruments and the improvement of IT systems, improvement of cybersecurity of data transfer posted on online platforms, databases and Big Data systems, social media portals, data processing platforms in the computing cloud, etc. in the open sorce formula.
I agree with the previous contributors Dariusz Prokopowicz and Len Leonid Mizrah
I also suggest that you consider carrying out a comprehensive literature review of latest research on study of cyber-attacks and cyber security and the emerging trends and recent developments from top journals and white papers.
That way you can be able to identify and analyse contemporary key global cybersecurity issues and with that understanding you can then propose a (Framework/Model/or Strategy) for cybersecurity. You can even integrate empirical data by interviewing or carrying out a survey on the issues you would have gathered from the literature review. That way can also help you to come up with a very solid paper.
