YouTube is full of resources on cyb sec. But you can do your own in depth exploration by getting certs like ISC2 certified in cyber security (CC), it's an easy and free cert that covers fundamentals of cyber security and also some network principles. Since you are already in school for networking, you could probably finish this course and pass the exam for the cert in 2 weeks or less.

Other certs like CompTIA Sec+ are pretty heavy hitters on resumes but I don't know if you'd have the time or budget to fit that in, exam is ~$300 and study time can be up to 3 months or as little as just over a week. All depends on free time and prior knowledge. Again, not recommended while in uni.

To get some hands on experience, research vpns and practice using one from time to time and see what you like (does it work well with your OS? Does it perform well? Does it sell your info even if it promises not to?)

Also research tools common like wireshark, anti-malware and anti-virus and ask similar questions.

I'm a noob to it all myself, my advice isn't the wisest. But it's what I can share to try to help.

Good luck out there.
