Welcome to this comprehensive course dedicated to Nmap (Network Mapper), the world’s leading open-source tool for network exploration and security analysis. Whether you are an aspiring security auditor or a system administrator, this program will teach you how to map a network and assess a system’s attack surface with professional precision.
The goal of this course is to teach you how to use Nmap to see what is truly visible and accessible from the network. You will discover how this tool manipulates raw IP packets to obtain rich technical information, far beyond the capabilities of a simple ping.
Throughout the lessons, you will learn how to:
- Install and configure Nmap on different environments (Windows and Linux) while mastering the flexibility of the command line.
- Specify targets with precision, whether it is a single IP address, a domain, or entire networks using CIDR notation.
- Master host discovery by identifying active machines even when they are protected by filtering mechanisms.
- Interpret port states (Open, Closed, Filtered, etc.) to understand the security measures in place.
- Deploy advanced scanning techniques (SYN, UDP, Connect, Xmas, NULL) to bypass firewalls and deeply analyze network behavior.
- Perform fingerprinting by accurately identifying service versions and operating systems of targets.
This course follows a pedagogical, professional, and defensive approach. It emphasizes a deep technical understanding of network protocols (TCP, UDP, ICMP) so that every scan result becomes a valuable source of information for your security audits.
Important note: The use of Nmap must be strictly limited to networks for which you have explicit authorization.
