Nmap

Nmap is a fast and powerful scanning tool that helps to look for ports, services, and even vulnerabilities in a target system. 

You will begin this course with the basic concepts of networking, like three-way handshakes and subnets. Then, you will learn about ports, protocols, and how they work together to establish a communication channel. Next, you will cover how to map an entire network of devices, including computers, mobile devices, printers, etc., to gather detailed information like open ports, services, and operating systems. Then, you will learn to evade detection and perform advanced scans like NULL scans, idle scans, and IP spoofing. You will finish the course by writing a simple port scanner from scratch using Python.

By the end of this course, you will be prepared to enter into any field of cybersecurity because this tool will help you to map an entire network of computers and gather data on individual devices on the network.
