DDoS Flooding Attack Mitigation in Software Defined Networks

Towards Autonomic DDoS Mitigation using Software Defined Networking

Distributed Denial of Service attacks (DDoS) have remained as one of the most destructive attacks in the Internet for over two decades. Despite tremendous efforts on the design of DDoS defense strategies, few of them have been considered for widespread deployment due to strong design assumptions on the Internet infrastructure, prohibitive operational costs and complexity. Recently, the emergenc...

Distributed packet pairing for reflector based DDoS attack mitigation

Reflector based DDoS attacks are feasible in variety of request/reply based protocols including TCP, UDP, ICMP, and DNS. To mitigate these attacks, we advocate the concept of victim assistance and use it in the context of a novel scheme called pairing based filtering (PF). The main idea of the PF scheme is to validate incoming reply packets by pairing them, in a distributed manner, with the cor...

Random flow network modeling and simulations for DDoS attack mitigation

Recent events show that distributed denial-of-service (DDoS) attack imposes great threat to availability of Internet services. In this paper, we study and evaluate DDoS attacks in a random flow network model, a novel and general approach to DDoS attack prevention and tolerance. The model can be used to evaluate the effectiveness of a DDoS countermeasure framework. Following the random flow netw...

Router Based Mechanism for Mitigation of DDoS Attack- A Survey

Today most of the activities like trade, e-commerce are dependent on the availability of Internet. The growing use of internet services in the past few years have facilitated increase in distributed denial of service attack. Due to DDos attacks, caused by malicious hosts secured data communication over the internet is very difficult to achieve and is the need of the hour. DDos attacks are one o...
