Answer 1

`Hey,

Note: If you have any queries related to the answer please do comment. I would be very happy to resolve all your queries.

1)

Nmap, short for Network Mapper, is a free, open-source tool for vulnerability scanning and network discovery. Network administrators use Nmap to identify what devices are running on their systems, discovering hosts that are available and the services they offer, finding open ports and detecting security risks. Nmap started as a Linux utility and was ported to other systems including Windows, macOS, and BSD. It is most popular on Linux, followed by Windows.

2)

PROS

• Open port scanning is a great tool to ensure your internal and external networks are secured.

• being able to identify endpoints and ensuring they are configured correctly.

• Great to be able to script within NMAP. It truly can be tailored to your exact needs

CONS

• I would say it's hard for new people using it as the there are too many switches.

• Better/faster udp scanning. I know that udp is best effort but something better would be great instead of waiting for timeouts.

• Scanning through proxies. Sometimes we need to masquerade ourselves before scanning and for that purpose scanning through proxies is done but Nmap’s proxy support is kind of broken.

Kindly revert for any queries

Thanks.
