Defending Systems Against Application-Level Denial of Service Attacks

Neural Network Based Protection of Software Defined Network Controller against Distributed Denial of Service Attacks

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...

HF-Blocker: Detection of Distributed Denial of Service Attacks Based On Botnets

Abstract—Today, botnets have become a serious threat to enterprise networks. By creation of network of bots, they launch several attacks, distributed denial of service attacks (DDoS) on networks is a sample of such attacks. Such attacks with the occupation of system resources, have proven to be an effective method of denying network services. Botnets that launch HTTP packet flood attacks agains...

A Distributed Framework for Defending Denial of Service Attacks

This paper investigate the behavior of DoS attacks while they are affecting the stability of computer systems as well as exploit a distributed framework which will monitor, detect, and prevent DoS attacks. This framework includes several distributed monitors implemented at the critical components and a management center which is used to detect and prevent DoS attacks.

Defending Wireless Infrastructure Against the Challenge of DDoS Attacks

This paper addresses possible Distributed Denial-of-Service (DDoS) attacks toward the wireless Internet including the Wireless Extended Internet, the Wireless Portal Network, and the Wireless Ad Hoc network. We propose a conceptual model for defending against DDoS attacks on the wireless Internet, which incorporates both cooperative technological solutions and economic incentive mechanisms buil...
