Distributed Denial of Service (DDoS) is a common attack in recent years that can deplete the bandwidth of victim nodes by flooding packets. Based on the type and quantity of traffic used for the attack and the exploited vulnerability of the target, DDoS attacks are grouped into three categories as Volumetric attacks, Protocol attacks and Application attacks. The volumetric attack, which the pro...

DDoS attack is a coordinated attack on massive scale and it is a major threat in current computer networks. It is not easy to detect the attack , The seriousness of the DDoS problem and the increased frequency of DDoS attacks have led to the advent of numerous DDoS defense mechanisms. Detection mechanism is the first step to avoid the DDoS attack. Some of these mechanisms address a specific kin...

Distributed denial of service attack(DDoS) brings a very serious threat to send to the stability of the Internet.This paper analyzes the characteristic of the DDoS attack and recently DDoS attack detection method. Presents a DDoS attack detection model based on data mining algorithm. FCM cluster algorithm and Apriori association algorithm used to extracts network traffic model and network packe...

Distributed Denial of Service (DDoS) attack is a large-scale, coordinated attack on the availability of services of a victim system or network resource, launched indirectly through many compromised computers on the Internet. Researchers have come up with more and more specific solutions to the DDoS problem. However, existing DDoS attack tools keep being improved and new attack techniques are de...

-A Distributed denial of service (DDoS) attack uses multiple machines operating in concern to attack a network or site. It is the most important security problem for IT managers. These attacks are very simple organized for intruders and hence so disruptive. The detection and defense of this attack has specific importance among network specialists. In this paper a new and smart taxonomy of DDoS ...

Distributed Denial of Service (DDoS) attacks have become a large problem for users of computer systems connected to the Internet. DDoS attackers hijack secondary victim systems using them to wage a coordinated large-scale attack against victim systems. As new countermeasures are developed to prevent DDoS attacks and help systems that are victims of such an attack, attackers are constantly devel...

Current trends in distributed denial of service (DDoS) attacks show variations in terms of attack motivation, planning, infrastructure, and scale. “DDoS-for-Hire” and “DDoS mitigation as a Service” are the two services, which are available to attackers and victims, respectively. In this work, we provide a fundamental difference between a “regular” DDoS attack and an “extreme” DDoS attack. We co...

Denial of Service (DoS) or Distributed-Denial of Service (DDoS) is major threat to network security. Network is collection of nodes that interconnect with each other for exchange the Information. This information is required for that node is kept confidentially. Attacker in network computer captures this information that is confidential and misuse the network. Hence security is one of the major...

recently, peer-to-peer (p2p) networks contribute to a large fraction of the internet backbone traffic. consequently, misusing such networks for malicious purposes is a potential side effect. in this review article, we investigate different techniques of misusing p2p overlay networks to launch large-scale next-generation distributed denial of service (ddos) attacks. in particular, we investigate...

Software Defined Network (SDN) is a new architecture for network management and its main concept is centralizing network management in the network control level that has an overview of the network and determines the forwarding rules for switches and routers (the data level). Although this centralized control is the main advantage of SDN, it is also a single point of failure. If this main contro...
