UDP traffic has recently been used extensively in flooding-based distributed denial of service (DDoS) attacks, most notably by those launched by the Anonymous group. Despite extensive past research in the general area of DDoS detection/prevention, the industry still lacks effective tools to deal with DDoS attacks leveraging UDP traffic. This paper presents our investigation into the proportiona...

The minimal processing and best-e↵ort forwarding of any packet, malicious or not, was the prime concern when the Internet was designed. This architecture creates an unregulated network path, which can be exploited by any cyber attacker motivated by revenge, prestige, politics or money. Denial-of-service (DoS) attacks exploit this to target critical Web services [1, 2, 3, 4, 5]. This type of att...

Distributed denial of service (DDoS) attacks on the Internet have become an immediate problem. As DDoS streams do not have common characteristics, currently available intrusion detection systems (IDS) can not detect them accurately. As a result, defend DDoS attacks based on current available IDS will dramatically affect legitimate traffic. In this paper, we propose a distributed approach to def...

Hackers uses Distributed Denial of Service (DDoS) and leaves hundreds and thousands of bots to overwhelm the victim in terms of bandwidth and reduce the services that are rendering to the users. To initiate an attack against victim, hackers use the internet as their venue. To address this threat various methods were proposed, but all the earlier method identifies the DDoS attack that exists in ...

In this chapter, we firstly review the short history of denial of service (DoS) and distributed denial of service (DDoS) attacks. We further explore the reasons why the current cyberspace is a heaven for cyber criminals, such as DDoS attackers. We present the challenges of the DDoS related research fields from various aspects, and discuss the possible research methods and strategies to serve th...

We propose a characterization of distributed denial-of-service (DDOS) defenses where reaction points are network-based and attack responses are active. The purpose is to provide a framework for comparing the performance and deployment of DDOS defenses. We identify the characteristics in attack detection algorithms and attack responses by reviewing defenses that have appeared in the literature. ...

This work proposes a novel approach to infer and characterize Internet-scale DNS Distributed Reflection Denial of Service (DRDoS) attacks by leveraging the darknet space. Complementary to the pioneer work on inferring Distributed Denial of Service (DDoS) activities using darknet, this work shows that we can extract DDoS activities without relying on backscattered analysis. The aim of this work ...

Denial of Service (DoS) attacks constitute one of the major threats and among the hardest security problems in today s Internet. Of particular concern are Distributed Denial of Service (DDoS) attacks, whose impact can be proportionally severe. With little or no advance warning, a DDoS attack can easily exhaust the computing and communication resources of its victim within a short period of time...

The Internet has experienced a tremendous expansion in its size and complexity since its commercialization. Internet hosts are threatened by large-scale Distributed Denial-ofService (DDoS) attacks in the network. DDoS attacks typically rely on compromising a large number of hosts to generate traffic to a single destination node. Thus the severity of DDoS attacks will likely increase to the poss...
