3. Introduction
 Nmap  Network Mapper is a free and open source
utility for network discovery and security auditing.
 Useful for tasks such as network inventory, managing
service upgrade schedules, and monitoring host or
service uptime.
 Developed by Gordon Lyon.
 Turned 20 years on September 1, 2017!
 CurrentVersion is 7.70.

4. Features
 Nmap uses raw IP packets in novel ways to
determine what
 hosts are available on the network,
 services (application name and version) those hosts
are offering,
 operating systems (and OS versions) they are
running,
 type of packet filters/firewalls are in use, and
dozens of other characteristics.
 It was designed to rapidly scan large networks,
it will work against single host too.
 Nmap runs on all major computer operating
systems.

5. Features
 In addition to the classic command-line Nmap
executable, the Nmap suite includes:
 an advanced GUI and results viewer - Zenmap,
 a flexible data transfer, redirection, and debugging
tool - Ncat,
 a utility for comparing scan results - Ndiff,
 and a packet generation and response analysis tool
- Nping.

11. Conclusion
 Network scanning provides information about the
target, which is valuable regardless of whether you're
trying to attack the network or protect it from attack.
 While performing a basic scan Nmap provides a wide
array of options to tweak your scan to achieve the best
results.
 These features can make scans more accurate, less
likely to be detected, and faster to complete.
 Nmap's huge list of features and solid implementation
make it the go-to scanner for most scans.
