Nessus UDP Scanner

Synopsis :

It is possible to determine which UDP ports are open.

Description :

This plugin runs a UDP port scan against the target. It is possible to
determine which UDP ports are open by sending UDP packets on every
port. If the port is open, the application will most often keep quiet.
If the port is closed, the TCP/IP stack may send back an ICMP Host
unreachable / bad port packet. If the target machine is protected by a
firewall, this technique cannot distinguish open ports from filtered
ports and fails. As the ICMP rate is often limited, this scan is slow.

Solution :

Protect your target with an IP filter or implement ICMP rate
limitation.

Risk factor :

None
