the best? no idea. but networking is a good and basic course 4 dat

For the very best background education, that’s entirely free, go to ‘Security Now’ podcasts with Steve Gibson & Leo Laporte.
These are 1hr. ‘sit down’ chats, that cover current issues, the how & why, with remedies for security issues, related to internet, networking, etc.
You’ll need to start with the early ‘casts because these are computer functions & basics, and occasionally it gets a bit tekky (and very often an ‘acronym tsunami’), but Steve & Leo do it in real easy to understand chat format, that makes it painless, fun, & interesting (if you like the tech stuff to start with).

College level education, free.

(IMHO: if you could master all the info in this series, you could pass a final test for an A.A.S. anywhere.)
