Introduction

Before diving into the installation of Nmap, it is essential to have an understanding of what is Nmap and its capabilities.

Nmap stands for Network Mapper. It is a robust open-source tool for inspecting, scanning, and managing networks. It is used by network administrators for network discovery and security scanning. 

They use Nmap to identify hosts, Operating Systems, services, and vulnerabilities on your network. In simple words, it is used to scan hosts and services on a computer network, thus creating a “map” of the network. 

Nmap is available for various operating systems, including Windows, Linux, and macOS. In this article, we will focus on how to install Nmap on Ubuntu. 

Let’s examine the different scenarios where in which Nmap can be utilized:

• Network mapping and inventory
• Vulnerability Assessment
• Security Auditing
• Testing firewall rules
• Discovering open ports on network systems
