A lot of security talk around these parts but not a recommendation of online security lab and training platforms like HackTheBox. Please try them out if you haven't. https://academy.hackthebox.com/catalogue After learning you can try out skills on their lab or CTF platforms. Training on these platforms let you understand how to make more secure applications. A very long time ago I had my kickstart in my work from doing CTFs. You used to need to hack the login form to get on this web site... I sucked at it and I still do, but you learn a lot extremely quickly and understand how things work far better than just reading on social media. Many people's questions or suspicions about things could be answered if they just did the security research on whatever they were suspicious about themselves... so do your proof of work.
