NetSec Noob looking for advice

Hi,

As the title says, I am a Security Noob and do not know really where to start for the challenges/machines. I do have a Computer Science background but I just do not have enough security theory to even utilize my CS skills. Do you guys know how I can get a theoretical grasp of security knowledge?

I have also looked into the OSCP classes and that looks useful.

I am open to any suggestions (besides “try harder” because I am doing that right now and it is not working)

Thanks!

I began with watchin ippsec/plaintext videos.
