碩士 === 東海大學 === 資訊工程與科學系 === 97 === Web servers face all kinds of users; some of them engage malicious activities, such as flooding attacks. As a result, lots of resource and bandwidth on web sites might be wasted. In this thesis, we propose a detection method, which is based on reverse proxy servers, to detect the flooding attacks. Our proposed method can be incorporated in a priority queue-based scheme to enhance quality of service for normal users. We have done performance evaluation of our method by implementing it on a server with heavy loads. The experimental results show that our method is effective in detection of malicious flooding attacks and is efficient in analysis and classification of traffic. The growth of process time of the detection method is linear, so it is suitable to be implemented on servers with heavy loads to improve their performance.
