Top UDP Ports Scan (Nmap)

Quickly scans the 100 most common UDP ports with a high packet rate, since full UDP scans are otherwise very slow.

Use this to get fast coverage of common UDP services, which are easy to miss because UDP scanning is slow.

Steps

• -sU selects a UDP scan.
• --top-ports=100 limits it to the 100 most common UDP ports for speed.
• --min-rate=20000 forces a high send rate so the scan finishes quickly.
