There's no introduction to the concepts. It simply drops a bunch of keys without explaining what's the logic behind

I liked the examples given, but this was more like a refresher course, not recommended for anyone just entering the tech side of computing.

One section could be added at the end on how exactly the RRSET is verified beneath the hood. Good course otherwise.

Simply amazing content... if you enroll do have basic DNS and PKI knowledge otherwise will find a bit hard.

Excellent tutorial, well explained, enjoyed it. Worthy of 5 starts but Section 2 Video 9 is missing the 1st minute of audio. Regardless, its a great course.

The course is a good introduction to DNSSec, although the most important part is missing (how to maintain the generated keys). There should be a follow up course explaining how to automate this tedious and repeating procedure. Part 2 / Chapter 9 lacks professionalism: the author issues several commands at the Linux terminal without speaking, burps (!) at about 0:27, and starts talking at 0:55. He should have edited the video before including it in the course!

I really enjoyed this course and got a lot out of it. Jimmy is very precise and thorough in the points that he covers. He presents the material in a very logical order and keeps you engaged. He hits all the bases for the beginner and intermediate student. He did such a good job on this course, that I bought all of his other courses as well.

Very good DNSSec introductory course. The methodical approach from the foundations through practical application to real world scenarios is nice. I would recommend this to IT professionals looking for a great way to refresh or learn about DNSSec
