PART A
Introduction
The Kali Linux is an operating system that is based on the Debian architecture and is mainly
used for vulnerability and security testing by ethical hackers and cyber security specialists.
The system helps the users identify the main loopholes in a connected networks. It is a free to
use software and is widely used for penetration testing and vulnerability detection purposes.
In this report, the use of nmap will be shown. It is a tool which can be used through Kali
Linux to scan large networks and single hosts alike. The tool helps in detecting vulnerabilities
of a given network and helps the user in identifying the security risks associated with his
system.
NMAP
Nmap tool has a wide number of functions. It is mainly designed as a free and open source
network scanner. It can be effectively used to find out services and hosts in a given computer
network. It can also be used for effective firewall testing and find out vulnerabilities in the
systems connected to a given network. It can be effectively used in a variety of other
operating systems like Windows, MacOS and BSD. However, it can be best used in Kali
linux to detect vulnerabilities.
The four main functions of the Nmap are:
1. OS detection: The Nmap feature can be used to detect the operating systems of computers
connected to a certain network. This feature can be used by hackers to detect the operating
system type and version of a given computer connected to the network. This will help them
plan an attack considering the vulnerabilities of the given operating system.

2. Network scanner: This Nmap feature is used to scan an entire network to detect the
computers and devices associated with it. On using this feature, the attacker will be able to
detect all the computers connected to the network and also know their IP addresses. This will
give the hacker an upper hand while stealing further information.
