I'm really interested in learning , but i don't know where.

I just started " trying " to learn Cybersecurity , and I've heard that first i should be knowing the basics of Networking .I've passed the Cisco " Networking Fundamentals " course , and my interest for Cybersecurity grew even more after . Rn i'm really curious if there's any other course that would give me a sort of entrance to Cybersecurity the same way that Cisco did , and FYI i'm a student so the few money i have only helps me not starving to death so a Free course would be preferable.
