Ask HN: Cyber Security Resources

Hello,

I'm starting to take my career in a slightly new direction, moving away from pure DevOps and over towards DevSecOps and eventually a pure Cyber Security role (if everything pans out.)

I'm wondering what resources you would recommend for something studying for their Security+, CySA+ and eventually their SSCP?

Also, does anyone know of a Hacker News equivalent for Cyber Security?

Thanks in advance.
