How To Scan UDP Ports
Nmap is one of the most used tools for port scanning. That's why we use Nmap for port scanning. Nmap has a wide variety of parameters and a lot of scripts to work on port scans.
What is UDP Protocol?
UDP (User Datagram Protocol) is a protocol (same as TCP) that defines rules to communicate with other systems in a network. TCP and UDP are both communication protocols in the network layer. But they are different from each other. TCP is connection-oriented, UDP is not. TCP makes sure that the messages reach the destination, UDP doesn't. UDP is used by protocols such as DNS, DHCP, TFTP, SNMP, RIP, VOIP. Also it is faster than TCP.
