Ethical Hacking: Network Security & Network Layer Attack

Welcome all to my cyber security “Ethical Hacking: Network Security & Network Layer Attack" course.
Learn Ethical Hacking with Network Security, Sniffing, Subnetting, Networking, Password Cracking & implement MitM attack

Whether you want to get your first job in IT security, become a white hat hacker, or prepare to check the security of your own home network, Udemy offers practical and accessible ethical hacking courses to help keep your networks safe from cybercriminals.

Our Student says that: This is the best tech-related course I've taken and I have taken quite a few. Having limited networking experience and absolutely no experience with hacking or ethical hacking, I've learned, practiced, and understood how to perform hacks in just a few days.

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.
