Preventing X-DoS Attack on cloud using Reputation-based Technology

Abstract

Cloud computing is a vast system which provides service based on usage to any number of users from any place using any device. But due to third party interference for maintenance and storage there are numerous denial of service attacks and other security attacks which affects not only the quality but also the cost due to resource consumption. And moreover the cost keeps increasing as long as the DoS attack is not detected at the earliest possible stage. Even though there are many security solutions to keep the attacks away still the DoS attacks take place stealthily due to some point of weakness in the system or the server or application.
The effect of the attack can be so brutalising that it can shutdown an organisation within few seconds and cause billions of damage. Hence special attention has to be given to the stealthy attack. In particular in this paper we are demonstrating X-DoS ttack which is one of the most common and dangerous attack that can degrade the system performance stealthily and maximize the financial damage on a cloud user. And also a method to detect X-DoS attack has been implemented in this paper. The Reputation-Based Technology detects the attack before the attack can actually take place. The RBT checks the reputation of each file before being sent for processing and only files with good reputation are processed thereby preventing X-DoS attack
