Cloud security defence to protect cloud computing against HTTP-DoS and XML-DoS attacks

Cloud computing is still in its infancy in regards to its software as services (SAS), web services, utility computing and platform as services (PAS). All of these have remained individualized systems that you still need to plug into, even though these systems are heading towards full integration. One of the most serious threats to cloud computing itself comes from HTTP Denial of Service or XML-Based Denial of Service attacks. These types of attacks are simple and easy to implement by the attacker, but to security experts they are twice as difficult to stop. In this paper, we recreate some of the current attacks that attackers may initiate as HTTP and XML. We also offer a solution to traceback through our Cloud TraceBack (CTB) to find the source of these attacks, and introduce the use of a back propagation neutral network, called Cloud Protector, which was trained to detect and filter such attack traffic. Our results show that we were able to detect and filter most of the attack messages and were able to identify the source of the attack within a short period of time.
