Executive summary:
The purpose of this paper is to discuss about Nmap tool which is known as network
vulnerability scanner tool. Nmap is basically used in kali Linux for penetration testing. In this
report, the discussion about firewall rule creation in kali Linux will be also done and on
behalf of that screenshots will be provided.

CYBER SECURITY 3
Introduction:
Nmap is a network vulnerability scanning tool that is used in kali Linux for
penetration testing on a network for identifying network vulnerabilities. In this paper a risk
mitigation plan will be prepared and some of the firewall rules will be created for securing
the network.
Nmap:
A common problem in the network system is that the network frameworks are very
much complicated for a normal person for understanding properly. For learning which port is
open as well as what are the rules, the tool called Nmap is used. The tool can scan the
network where the computers are connected as well as provide output a list of the ports,
operating systems, name of the devices etc. The tools can be used by the attackers for gaining
access to the ports that are uncontrolled. If a hacker can install the Nmap tool in a system
then the attacker will be having the ability to control the system.
Below is the result of a network scanning by Nmap:
