Course Overview

This course is designed to introduce aspiring cybersecurity professionals and network administrators to Nmap (Network Mapper), an essential tool for network exploration, security auditing, and penetration testing. Students will learn how to effectively use Nmap for various network tasks while understanding the underlying principles of network scanning.

Course Outline

1. Introduction to Nmap

   • What is Nmap and its importance in network security

   • Understanding ports and services

2. How Nmap Works

   • Nmap architecture and components

   • Understanding TCP/IP networking basics

   • Nmap’s scanning process and methodology

3. Host Discovery Techniques

   • TCP SYN/ACK scanning

   • UDP scanning methods

4. ICMP Scanning

   • ICMP echo (ping) scanning

   • ICMP timestamp requests

   • Advantages and limitations of ICMP scanning

5. Different Scan Types

   • TCP connect scan

   • TCP SYN (stealth) scan

   • UDP scan

6. Useful Nmap Switches

   • Timing options (-T)

   • Verbosity and debugging (-v, -d)

   • OS and version detection (-O, -sV)

7. Security Practices

   • Avoiding detection and reducing network impact

   • Best practices for secure scanning

8. Nmap Scripting Engine (NSE)

   • Introduction to NSE

   • Running basic scripts

By the end of this course, you will be able to:

• Understand the fundamentals of network scanning and discovery
