Zenmap is the graphical User Interface representation for
NMAP Security Scanner. It is an open-source program designed to make NMAP easy
for starters to use. Typically, it is used to collect and identify a list of
hosts, OS, as well what services are running on them by using a port scanning
tool. It is used specifically for the scanning and vulnerability phase of
ethical hacking.
A network administrator who wishes to audit all the devices
on a specific IP scheme in a network can use NMAP. The admin can go ahead and
scan the ports to know exactly which ports are closed and which
are opened.
It takes a lot of time and effort to write the code for the same. It is very complex and difficult to understand. The syntax is difficult to remember. It has a lack of portability of program between different computer architectures.
Hope that helps
