A Novel Approach For Resisting Web Proxy Attacks By Using TSL Behavior

Abstract :

Web proxy based HTTP attack has been a serious threat to server security due to the covert nature. Although most of the large scale official proxies are usually configured to have high security, they cannot avoid being abused for the proxy based attacks. Such type of attack is not easy to be discovered by most existing defense systems since the real attacking hosts are shielded by the hierarchical Web proxies. In this paper a novel server–side defense scheme is proposed to resist such covert indirect attacks. This approach extracts the temporal and spatial locality behavior of the proxy to server traffic independent of traffic intensity and frequently varying Web content. Then, Web proxy’s access behavior can be directly mapped into a HSMM parameterized by Gaussian mixture and Gamma distributions. A novel attack response method named soft control is proposed. This scheme reshapes the suspicious sequence into a relatively normal one by partly discarding its most likely malicious requests instead of denying the entire sequence. So it can protect the quality of service of users. Finally, experiments are conducted to validate the model
