First I apologise to my english readers but it would be a French resources only but which is worth being mentioned.
So the initiative ConfsFR aims to explain and make understand how internet works ; Two sessions happened since early september : the first one was about DNS and the second one about SSL/TLS and it was introduced by brilliant people on each matter. I don"t know to what extend it is accessible for novice but if you have some technical background or some knowledge about these topics, you will learn a lot.
On the site, you will find link to slides, to the video recording of the session, etc. For videos, you can see them on the dedicated channel (site is not yet updated)
If you can't attend next conference, it may be broadcasted when the event is located at "La Cantine" (co-working place in Paris). It's how I managed to watch most of the SSL/TLS session.
