This brief course will cover the OSI model layer by layer and go through some practical applications of these layers in the networking field. Students will begin to understand what is the function of each of the layers and they will be able to connect the layer number to the layer name.

For instance, they will know that layer 3 is the same as the network layer and what protocols are functional at each of the layers and what are the responsibilities of each layer.

This will be a good foundational course for the students who want to further pursue a networking career. This can further build on this basic knowledge to take it further. The Absolute Beginners Guide to Cyber Security Part 1

Section 1:

We start off where we left, in the previous course on “The Absolute Beginners Guide to Cybersecurity & Hacking” we dealt with the fundamental concepts such as Basic Network, CIA Triad, Network concepts, Security Operations Center and Job Roles. Section 1 starts with a refresher on network concepts, topologies, etc and connects you to the previous course.

Section 2&3:

These two sections give a good insight into the OSI Model and all the Layers:

a)Physical layer b)Data link layer c)Network layer d)Transport layer e)Layered packet format f)Flow control g)Error control

f)Connection-orientedness vs connectionless g)Session layer and responsibilities h)Presentation layer and its

responsibilities i)Summary of layers

Section 4:

In this section, students will learn important concepts like the TCP/IP protocol suite and Domain name system hierarchy. The Absolute Beginners Guide to Cyber Security Part 1
