Contents are good, however, it is not beginner friendly. Need to make more easier to understand. YouTube has more rich ideas about Networking. Important note is students look for simplicity or a simple way to understand the basic.

Thorough introduction into network security, protocols, common vulnerabilities, malware and exploits, as well as tools commonly used in the field, highly recommend it, enjoyed every second of it!

Great Introduction to some basic network security concepts, terminology, and domain perspective alignment for such a role.

I have taken some network courses and this one is by far the best, clear explanations, deep concepts, and good examples
