Everyone says to do HTB or tryhackme, which are both great resources. However, if you don’t have an IT background and you don’t know how computers work, you’ll just be learning tools without any real background. I’d recommend starting with background info like OS, C programming, and networking. Once you have a baseline in those, go study for the CompTIA Security+ cert. you don’t necessarily need to take the exam right away, but the information is a great baseline to branch out into other topics
