Protocol Share Based Traffic Rate Analysis (PSBTRA) for UDP Bandwidth Attack [chapter]

Zohair Ihsan, Mohd. Yazid Idris, Khalid Hussain, Deris Stiawan, Khalid Mahmood Awan
2011 Communications in Computer and Information Science  
Based on these two characteristics, a UDP bandwidth attack detection system based on Protocol Share Based Traffic Rate Analysis (PSBTRA) is proposed.  ...  There are two main characteristics of bandwidth attack. First, during an attack the incoming traffic rate is much higher than the outgoing traffic rate.  ...  "Distributed denial of service attack is a denial of service attack, in which a multitude of attackers performs denial of service attacks in a coordinated manner to one or more targets."  ...
