Protecting Cloud Web Services From HX-DoS Attacks Using Decision Theory

With the coming of Cloud computing, web services provider are now looking to move their services over to it. Amazon EC2 is an example of such a provider. With this move over to the Cloud, cloud web services inherit a major security problem, the HX-DoS attack. HX-DoS attack is a combination of HTTP and XML messages that are intentionally sent to flood and destroy the communication channel of the cloud service provider. The relevance of this research is that TCP/IP flood attacks are a common problem and a lot of research to mitigate them has previously been discussed. But HTTP denial of service and XML denial of service problem has only been addressed in a few papers.
