Performance Evaluation of Modbus TCP in Normal Operation and Under A Distributed Denial of Service Attack

Analysis of a Denial of Service Attack on TCP

This paper analyzes a network-based denial of service attack for IP (Internet Protocol) based networks. It is popularly called SYN flooding. It works by an attacker sending many TCP (Transmission Control Protocol) connection requests with spoofed source addresses to a victim’s machine. Each request causes the targeted host to instantiate data structures out of a limited pool of resources. Once ...

Defending against a Denial-of-Service Attack on TCP

In this paper we propose a method for detecting TCP SYN-flooding attacks. This is an anomaly detection method based on intensities of SYN segments which are measured on a network monitoring machine in real-time. We note that current solutions suffer from several important flaws such as the possibility of denying access to legitimate clients and/or causing service degradation at protected machin...

WDA: A Web farm Distributed Denial Of Service attack attenuator

Distributed Denial Of Service (DDoS) attacks are familiar threats to Internet users for more than ten years. Such attacks are carried out by a “Bot net”, an army of zombie hosts spread around the Internet, that overwhelm the bandwidth toward their victim Web server, by sending traffic upon command. This paper introduces WDA, a novel architecture to attenuate the DDoS attacker’s bandwidth. WDA i...

Distributed Denial of Service Attack Detection in Wireless Sensor Networks

Wireless sensor networks have emerged as a significant source for the study and analysis of data from the environment. These networks are deployed in harsh and inaccessible environments with the purpose of monitoring their respective surroundings, and generating observed readings, for delivery to a centralised entity, for further data analysis. Sensor nodes are tiny devices with limited availab...
