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.

Personally, I found this course more dense than the previous courses. I would have liked to have seen more visual descriptions of the topics, e.g. cryptography. But other than that, great course :)
