In this paper, we focus on defending the DDoS attacks since they have caused many famous websites enormous losses in recent years. We propose a Priority Queue-Based scheme to analyze the interval of arrival time of the incoming packet to distinguish malicious traffic from normal traffic and to take care of malicious attacks clogging the network. We use the network simulator, NS2, to evaluate the effectiveness...
Web servers face all kinds of users; some of them engage malicious activities to degrade or completely block network services, such as flooding attacks. As a result, lots of resource and bandwidth on web sites might be wasted. In this paper, we propose a detection method based on reverse proxy servers to detect the flooding attacks. Our proposed method can be incorporated in a priority queue-based...
A Distributed Denial-of-Service attack affects the bandwidth or resources of a targeted system. By flooding networks and disrupting access to services, it may cause damage on multimedia network services and Internet Service Providers. In the paper, we propose to analyze the behavior of packet flows and adopt a priority queue-based algorithm that assign packets from normal users to a high priority...
