DESCRIPTION: The second UDP method is UDP Fragmantaton, which is not different from UDP Flood when comes to detection, mitigation. Therefore, you can use exactly the same methods described under "UDP Flood".

The only difference is in the detectoin. In case you observe too many of UDP packets which lack destination ports, this is an indicator of the attack.

As per its implementation, it uses the same logic which we described under other Fragmantation lectures.


A very shady and unstable method, which should be used only as a last resort, is checking the incoming packets as per their TTL (Time-to-live) and block at the router per their TTLs.

This is not a reliable method and will most probably block some of your legitimate users (with the same TTL). However, in case all other mitigation methods fail and the attack is starting to take down the server and you have defined a common path on TTL from the attacker, you can give it a try.
