Hello thanks for joining me and welcome to the network fundamentals course.
My name is Muharrem Aydin. I'm a computer engineer, cyber security expert and I'm going to be your instructor. Let
me give you a neurally heads up.
This of course will give you theoretical information about computer networks in general so we won't
be doing a lot of hands on demo this time.
But let me point out something else.
I'm not going to claim to teach you everything about networking.
Instead I'll explain the basics of networking and the most common protocols from the cyber security point
of view.
You see a penetration tester needs to know the fundamentals of computer networking. Makes sense right?
So here's the content of the course.
First we'll have a brief look at the networking concept, then more talk about the two most well known
network models. The OSI reference model and the TCP/IP reference model.
And then we're going to learn each of the network layers and their most important protocols in detail.
Datalink layer, network layer, transport layer
and finally the application layer.
