Nmap basics
Nmap is a network scanning tool that can perform port scanning, operating system detection, and version detection among other features. It works by sending TCP and UDP packets to a target machine and examining the response, comparing it to its database to determine open ports and operating system. There are different scanning techniques that can be used like TCP SYN scanning, UDP scanning, and OS detection. Nmap also includes a scripting engine that allows users to write scripts to automate networking tasks. The presentation concludes with demonstrating Nmap's features through some examples.

- 4. Before we proceed... DoYou Think Nmap is just a port Scanner ?
- 5. Features • Nmap wasfirst published in September 1997 • Included operating system fingerprinting • Service fingerprinting • Code rewrites (C to C++) • Additional scan types, • Protocol support • New programs that complement Nmap's core features
- 6. How Nmap Works 1)Sends TCP and UDP packets to the target machine 2) Examines the response by comparing the result with the database 3) OS detection involves the process of finding open ports 4) Ping scan uses ICMP packets to check live machines within the network 5) Nmap is not limited to merely gathering information and enumeration
