Ethical Hacking:Network Fundamentals & Network Layer Attacks

Learn Ethical Hacking with Network Security, Sniffing,Subnetting, ARP Spoof, Password Cracking and implement MitM attack

Created by Muharrem AYDIN - Computer Engineer, Ethical Hacking, Cyber Security Expert


Students: 4884, Price: $99.99

Students: 4884, Price:  Paid

Welcome all to my cyber security course “Cyber Security: Network Fundamentals & Network Layer Attacks“ course.

To become Ethical Hacker and to learn hacking my Network Layer Attacks and Network Fundamentals course is a perfect start for you. This one gets kind of fun because we get to actually look at data going on the networks like: how to sniff the network and gather information from the network. We’re going to use some tools such as TCP Dump and Wireshark. We will also be doing a deep dive into the Subnetting, ARP Spoofing and MitM attacks and Password Cracking.

This course is highly practical just like my other courses. But which also does not mean that I will neglect the theory. That`s why this course is formed in two parts.

First part, “The Network Fundamentals” is for the beginners to explore the Network Fundamentals but also could be also a good refresher for advanced level students.

In Network Fundamentals section I will introduce you to the fundamental concepts of data networking operation including IP addressing and subnetting, ethernet operation, ports and protocols, and the OSI model . By the end of this course, you will understand the relationship between IP addresses and MAC addresses, as well as the difference between a router and a switch.

After learning theoretical background  ( I promise that second part is totally fun ), in Network & Data Link Layer ( Layer 2 ) Attacks part you will first learn how to set up a lab and install needed software to practice penetration testing on your own machine. Then we’re going to use some tools such as TCP dump and Wireshark and  we’ll see some attacks and techniques to expand the sniffing surface:

  • MAC Address Table Overflow attack, also known as MAC flooding,

  • ARP Cache Poisoning attack, also known as ARP spoof,

  • DHCP Starvation attack and DHCP spoof,

  • And VLAN hopping techniques.

The next topic is what else can be done on network devices in penetration tests: Gathering information, cracking passwords of the communication channels, compromising SNMP, etc.

And finally, we’ll check the configurations of network devices: Password creation methods, Identity Management, Access control lists, port security, etc.

This course will take you from a beginner to a more advanced level. Please enjoy and if you have questions do not forget to get in touch with me.

IMPORTANT!!!: This course is created for educational purposes and all the information learned should be used when the attacker is authorized.

About this course!

Maybe some of you are not even in the IT industry yet, or maybe some of you are stuck at the bottom in a position you really don’t care for. Maybe you need to prep for  your Cisco CCNA exam but just keep getting soo overwhelmed with the amount of material, or maybe your are having a hard time knowing where to begin or, maybe your just having trouble staying on track with your studies. Well, let me tell you something - if you fall into any of these situations.. LOOOK NOOOO FURTHER!


Although this is an Introduction course… guess what!  

We are going to be covering many important topics in this course related to Cisco’s curriculum, to get you ready and get that ball rolling! I specifically designed this course so you can see the basics of a lot of the main topics, and have a solid understanding of them. This way, when you dive into my full ccna course, or any of the other awesome instructors ccna courses out there, the foundation is already set. So what do I mean by all of this? It means  youll have a clear, basic understanding of all the overwhelming amount of information in the full ccna course, and when you begin your Full CCNA course, you will then only be required to fill in the missing details to have a full understanding and to successfully pass your cisco exams.


So, how am I going to do this? 

Well, This course will be comprised of two major components.


First comes Theory – Yes the boring stuff, but - You need to understand some key terms, protocols, and well fundamentals as a whole so you can have a good basic understanding of what is going on, and really to know what the heck networking even is. I promise if you listen to the information I present you, you review the information, study the information… you will be golden. You will have that foundation you need to move forward with the Full CCNA curriculum.


Next, we have  Practical – Yes the FUN stuff, like hands on labs! Like most of us out there, a lot of us are hands on learners and we need to physically configure or build something to see how its actually working. Well, this course will be made up of about 2 thirds of labs. You will learn how to install a virtual network simulator, and learn every basic component for switches and routers, and then we will begin configuring them. We will start off building simple labs, and then review all the Theory we learned while building these simple labs at first so all the informtion you learned before this LABS section will make more sense, and you physically see them working together. Once we start getting the basics covered, we will move into more complex labs and really start building some nice labs with many different features. By the end of the practical section, I promise... you will be able to configure a small office, home office Local Area Network, using cisco hardware, and be able to troubleshoot these networks for any network issues.


So, is this course for you? Well, only you can really make that assumption. I will encourage you to consider this course as I said, it will make your life easier when you dive into the Full CCNA curriculum. You wont spend so much time trying to retain so much information at once.  This course, we keep the material to the basics and key points so it makes sense. Yes you will have to study and put a little work in on your end, but if you work with the material and tools I give you, you will be set!


If you have any questions what so ever, please leave me a message or personally shoot me an email. One thing to know is that if you're ever in need of help – I am here for you! 


So, without further ado, I hope you make the right decision which fits your current level of knowledge and education best. If you are new this whole IT and Networking industry, and you feel that this course would be right for you, I really look forward to being a part of your journey!

Network Theory: Introduction

Learn the Language of Networks

Created by Systems Innovation - eLearning for systems thinkers


Students: 534, Price: $34.99

Students: 534, Price:  Paid

Network theory is one of the most exciting and dynamic areas of science today with new breakthroughs coming every few years as we piece together a whole new way of looking at the world, a true paradigm shift that is all about connectivity. The study of network theory is a highly interdisciplinary field, which has emerged as a major topic of interest in various disciplines ranging from physics and mathematics, to biology and computer science to almost all areas of social science.

From the metabolic networks that fuel the cells in our body, to the social networks that shape our lives, networks are everywhere, we see them in the rise of the internet, the flow of global air traffic and in the spread of financial crises, learning to model and design these networks is central to 21st century science and engineering.

This is an introductory course where we present topics in a non-mathematical and intuitive form that should not require any specific prior knowledge of science as the course is designed to be accessible to anyone with an interest in the subject. During the course we will explore all the major topics including:

Networks Overview: In this first section to the course we are going to give an overview to network theory that will also work as an overview to the structure of the course and the content we will be covering. We talk about what we called the network paradigm that is the whole new perspective that network theory offers when we look at the world through the lens of connectivity.

Graph theory: In this second section we lay down the basics of our language for talking about graphs by giving an introduction to graph theory, we talk about a node's degree of connectivity and different metrics for analyzing a nodes degree of centrality and significance within a network

Network Structure: In the third section we explore the overall topology to a network by talking about connectivity, that is how connected the whole network is, diameter, density and clustering all key factors in defining the overall structure to a network.

Types Of Networks: In this section we will be looking at different models to networks by starting out with a randomly generated network we will see how most network are in fact not random but have some distinct structure, here we will be talking about a number of different models such as centralized scale free networks and the small world phenomena.

Network Diffusion & Dynamics: In the last section to the course we touch upon how networks change over time, in particular looking at the different parameter affecting the generation of a network, how something spreads or fails to spread across it and finally wrap-up by talking about network robustness and resilience.

n00b To Ninja

Think You Understand The Basics?

One of the questions we often see goes like this: "Do I need to pass the CompTIA Network+ exam before taking the Security+?"

Now this is an excellent question because, although the Security+ exam doesn't have any prerequisites it is still highly recommended that all students have a firm understanding of basic networking technologies.  

The n00b to Ninja course is a great prep tool to get you mentally and psychologically ready to tackle the Security+ exam (but you can also use it to simply gain a better understanding of how networks work)

What You Will Learn

  • Networking Basics from the ground up (everything everyone already THINKS you know but you know you don't)

  • Routers and Switches - what they really do and why we need them

  • All about DHCP - it's not just about automatically getting an IP address

  • BONUS: DHCP penetration testing attacks to show you how an attacker might abuse DHCP on a local area network

  • DNS from A to Z.  After this lecture you will finally completely understand what DNS is, why we have it and how it really works. All secrets revealed.

  • ARP: Have you ever wondered why we have both MAC addresses and IP Addresses?  Have you been confused about this?  After this lecture you'll know why we need both (Hint: 90% of IT professionals don't even know the answer to this basic question - but you will after completing this lecture)

  • You'll learn all about IP addresses - we'll break it down to the binary level and show you how to convert between binary and decimal and back again

  • You'll learn the purpose of the Subnet Mask and how (and why) to Subnet Networks - it's a lot easier than you think

  • All about NAT - the greatest inhibitor to innovation but also the reason the internet hasn't collapsed on itself!  IT people like to throw this term around but you'll finally GET it - it'll just make sense after you finish this lecture.

  • All about ports - what are ephemeral ports, well known ports - why we have ports - all that jazz 

  • WAN technologies - we'll take a step back and look at the internet at large and how routing protocols work.

Here's what this course will do for you

The purpose of this course is really simple: to give you the confidence you need to pass the Security+ exam.

Sure you're going to have fun along the way, and sure you can use these skills to stay in your current job and be a more competent employee but we designed this course to spring-board your entry into the exam. 

Once you know the fundamentals taught in this course you'll not only be better prepared but also eager to begin your studies for the Security+ exam.

This will further simplify the concepts and will resolve your doubts also. I am providing a document listing all the topics of the course, which will give you a clear picture of the course that is downloadable.

Some more lectures are there in the new update. (new section on IP Addressing and Subnetting)

After you complete the course text me on Course Message and I will fix a doubt session with you where you can ask questions about the course. ( Nothing is being marketed in this session).

You will acquire all the fundamental knowledge of computer networks with this course.

A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes. The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.

The nodes of a computer network may be classified by many means as personal computers, servers, networking hardware, or general-purpose hosts. They are identified by hostnames and network addresses. Hostnames serve as memorable labels for the nodes, rarely changed after the initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol.

Some of the topics related to this course are

  • Data Communication basics,

  • MUX and DEMUX,

  • Transmission Media,

  • Topologies,

  • Protocol Stacks,

  • OSI Model,

  • TCP/IP Model,

  • Switching

  • IP Addressing

  • DNS,

  • Information Security.


Computer Networking is easy, trust me. See you on the other side of the course.
