Detecting DDoS Attacks Using Dispersible Traffic Matrix and Weighted Moving Average
Distributed Denial of Service (DDoS) attacks have become significant threats on Internet according to the development of network infrastructure and recent communication technology. There are various types of DDoS attacks with different characteristics. These differences have made very difficult to detect such attacks. Furthermore, the sophisticated the evolution of DDoS attacks techniques and t...
متن کاملFast Detection of Ddos Attacks Using Non-adaptive Group Testing
Network security has become more important role today to personal users and organizations. Denial-ofService (DoS) and Distributed Denial-of-Service (DDoS) attacks are serious problem in network. The major challenges in design of an efficient algorithm in data stream are one-pass over the input, poly-log space, poly-log update time and poly-log reporting time. In this paper, we use strongly expl...
متن کاملCollaborative Defense Mechanism Using Statistical Detection Method against DDoS Attacks
Distributed Denial-of-Service attack (DDoS) is one of the most outstanding menaces on the Internet. A DDoS attack generally attempts to overwhelm the victim in order to deny their services to legitimate users. A number of approaches have been proposed for defending against DDoS attacks accurately in real time. However, existing schemes have limits in terms of detection accuracy and delay if the...
متن کاملEffective DDoS Attacks Detection Using Generalized Entropy Metric
In information theory, entropies make up of the basis for distance and divergence measures among various probability densities. In this paper we propose a novel metric to detect DDoS attacks in networks by using the function of order α of the generalized (Rényi) entropy to distinguish DDoS attacks traffic from legitimate network traffic effectively. Our proposed approach can not only detect DDo...
متن کاملEvading DDoS detection with mimicry attacks
Distributed Denial of Service (DDoS) attacks are security attacks that prevent normal use of communication facilities. More and more DDoS attacks are occurring each day. Conventional DDoS attacks are typically based on flooding the server. Currently, other types of DDoS attacks have been observed, such as the mimicry DDoS attack. The mimicry attack is characterized by (1) gradual increase in th...
