Scheme of Defending Against DDoS Attacks in Large-Scale ISP Networks
نویسندگان
چکیده
A scheme that defending against distributed denial of service (DDoS) attacks adopts the mechanism of Distribution-based Secure Overlay Nodes (DSON) to a large-scale ISP (Internet Service Provider) network is presented. The scheme uses local BPG announcement to divert traffic to the overlay network when experiencing high load, then filtering algorithm based on the technology of signal processing is applied to the diverted traffic. This algorithm detects and filters out DDoS attacks in frequency domain to allow targets to provide good service to legitimate traffic, with fast reaction and high energy ratio of legitimate to attacks traffic. DSON is implemented and installed on the monitor points of large-scale ISP network associated with the corresponding routers, edge router, border router, and core router, with no requirement for the modifying to network architecture, infrastructure, and protocol.

Robust and efficient detection of DDoS attacks for large-scale internet
In recent years, distributed denial of service (DDoS) attacks have become a major security threat to Internet services. How to detect and defend against DDoS attacks is currently a hot topic in both industry and academia. In this paper, we propose a novel framework to robustly and efficiently detect DDoS attacks and identify attack packets. The key idea of our framework is to exploit spatial an...
متن کاملProtection from distributed denial of service attacks using history-based IP filtering
In this paper, we introduce a practical scheme to defend against Distributed Denial of Service (DDoS) attacks based on IP source address filtering. The edge router keeps a history of all the legitimate IP addresses which have previously appeared in the network. When the edge router is overloaded, this history is used to decide whether to admit an incoming IP packet. Unlike other proposals to de...

Distributed Denial of Service attacks pose a serious threat to the online applications like banking, trade, and e-commerce which are dependent on availability of Internet. Defending Internet from these attacks has become the need of the hour for sustainable development of any economy. Most of the research work in this area focuses on developing defense against these attacks without considering ...
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...
