See both the field you have mentioned are great. Now from a broad perspective, I would say having a specialization in Data Science will provide you a much better perspective compared to that of Cyber Security. See data science is getting more and more scope to be applied from the lower to higher level problem solving. So if you go for the course of Data Analysis you will have a more broader perspective of job as well as job positions.

Now Cyber Security experts are also needed but they are recruited lesser in number compared to the Data Analyst per company. So if you want to get a broader job scenario, go for the course of Computer Science with Data Analysis.
