For the best background education; primarily on security %26amp; technical aspects: entirely free, go to 'Security Now' podcasts with Steve Gibson %26amp; Leo Laporte.
These are 1+ hr. 'sit down' chats, that cover current issues, the how %26amp; why, with remedies for security issues, related to internet, networking, etc.
Start with the early for computer functions %26amp; basics, and occasionally it gets a bit tekky (and very often an 'acronym tsunami'), but Steve %26amp; Leo do it in real easy to understand chat format, that makes it painless %26amp; interesting (if you like the tech stuff to start with).
College level education, free.
