Well, I think so, but it seems we have to learn the basics first to be able to know at least, and then we can learn the advanced level with online courses with some practice, although I wish there was offline learning, because I feel it would be easier to learn that way.
Actually youre right. Upon researching with the basics I find it hard to actually learn it and needed massive focus. So Id find it able to see that these tutorials can somehow help total beginners with 0 experience on that. Any beginnet will be needed to adjust and learn the fundamental of security itself.
