I feel like this went way more in depth than I think most people just getting into it can handle. I think either this needs to be dumbed down or drawn out a bit more, but a lot of great info.

A more in-depth concept can be included in the course and provide a reference to open source tools/technologies so young and aspiring security professionals can gain more out of this course.
