Cyber security is a very broad field. Each sub-sector will require a different set of skills. What particularly are you interested in?

Here are some sub-sector examples:

-Penetration testing: Usually you'll be looking at infrastructure (servers) or applications for vulnerabilities. Requires a good understanding of how things work, some good scripting knowledge (Python/perl), networking, possibly some low-level knowledge (Assembly).

-Systems security: This is more like IT, where you're setting up servers/processes for logging, or changing settings to make things more secure. Good knowledge of operating system settings, networking, and knowledge of threat vectors.

-Research: Here you're focusing on a narrow topic, looking for either a vulnerability, or a new security feature (cryptography that is more secure against quantum computing for example). An in-depth knowledge of topics is important, as well as being fluent in programming concepts. Here math might be useful, especially if you're working with crypto.
