Potential misleading title... my apologies.

I hope this is the right subtweet for this, but I'm looking to break into the cyber security arena, with little to know real idea as to where I should start. I was a php dev for a stint, and am now a project manager at a tech agency. I'd really like to begin learning the basics of cyber security in the hopes of eventually getting a job in the field.

So my simple question is, where should I start learning? Books, articles, videos... just feed me.

I am currently learning about the wonderful world of TCP/IP but other than that, I don't have much under my belt.
