Hello, I am new here, so if this question was already answered I would appreciate a lot if you put the link of the thread in the comments.

I am a Junior Web Developer, and I like cybersecurity a lot. I do know a thing or two about cybersecurity, but I really want to start taking it serious and start really learning how things are hacked and how to prevent my web applications from being hacked. Do you guys have any tip, content, book, anything that can help someone who is freshly new to start learning cybersecurity for web applications?
