Defending against distributed denial-of-service attacks is one of the hardest security problems on the Internet today. One difficulty to thwart these attacks is to trace the source of the attacks because they often use incorrect, or spoofed IP source addresses to disguise the true origin. In this paper, we present two new schemes, the Advanced Marking Scheme and the Authenticated Marking Scheme...

<span lang="EN-US">Distributed denial of service (DDoS) attacks the target providers by sending a huge amount traffic to prevent legitimate users from getting service. These become more challenging in software-defined network paradigm, due separation control plane data plane. Centralized software defined networks are vulnerable DDoS that may cause failure all networks. In this work, new a...

The paper considers an approach to modeling and simulation of Distributed Denial of Service (DDoS) attacks fulfilled by a group of malefactors. The approach is based on combination of “joint intentions” and “common plans” theories as well as state machines. The formal framework for modeling and simulation of DDoS) attacks is presented. The architecture and user interfaces of the Attack Simulato...

The Denial of Service attack, especially the Distributed Denial of Service (DDoS) attack, has become one of the major threats to the Internet. Generally, attackers launch DDoS attacks by directing a massive number of attack sources to send useless traffic to the victim. The victim’s services are disrupted when its host or network resources are occupied by the attack traffic. The threat of DDoS ...

Denial-of-Service attacks and Distributed Denial-of-Service attacks are serious security problems over the Internet due to their nature. They are easy to implement, hard to prevent, and very difficult to trace. This paper describes Denial-of-Service attacks and Distributed Denial-of-Service attacks and presents various traceback that are proposed to identify the sources of theses attackers in t...

VANET (Vehicular Ad-hoc Network) which is a hy- brid network (combination of infrastructure and infra- structure-less networks) is an emergent technology with promising future as well as great challenges especially in security. By the other hand this type of network is very sensible to safety problem. This paper focuses on a new mechanism for DoS (denial of service) attacks on the physical and ...
