What do I need to learn if I want to work in cyber security?

So I’ve finally figured out long-term goals for what I want to do and where I want to end up in IT. It looks like more than likely I will be going to university this year and doing a bachelor in IT with the end goal of working in Cyber security.
Is there anything I should do study-wise or need to learn to work in cyber I could be doing between now and when I start the degree?
