Ethical Hacking; Basic Concepts of Networking

This course will begin by introducing you to ethical hacking. You will learn about the differences between penetration testing and ethical hacking. You will learn about the roles of an ethical hacker and terminologies used in ethical hacking. You will also learn the different ways through which an ethical hacker can gain access to a system.

The course then explains the different types of computer networks, the difference between circuit switching and packet switching mode of data transfer. You will learn about datagrams and layered network architecture. Next, you will learn about the TCP/IP stack along with the basic functions of TCP, UDP and IP. You will also learn about IP Datagrams and IP Header fields.

Finally, you will learn about IP addressing and routing. You will learn about IP packet fragmentation and the types of fragmentation. You will also learn the roles of TCP, UDP and IP subnetting in the context of networking. You will learn about IP subnetworks, also called subnets and gain significant knowledge on IP masks, how they are used along with methods of creating subnetworks - VLSM and CIDR.
