What is Nmap ?

Nmap, short for Network Mapper, is a free, open-source tool for vulnerability scanning and network discovery.

How does it work ?

Nmap sends raw ip packets to the target machine and then it examines the response by comparing the result with the database.

When should you use it ?

• When you want to identify what devices are running on their systems
• When you want to discover hosts that are available and the services they offer
• When you want to find open ports and detecting security risks

Example:

nmap synscan from kali linux to a vulnerable vm
