Distributed Denial of Service Attack and its Countermeasures

Countermeasures against Distributed Denial of Service A Literature Review

A distributed denial-of-service (DDoS) attack is carried out by simultaneously by compromised systems against targets causing system and service unavailability. Regardless of industry and size, companies worldwide are increasingly becoming target of DDOS attacks. The sophistication and intensity of these attacks are exponentially rising due to increase in number of compromised systems, unpatche...

Remote Denial of Service Attacks and Countermeasures

As evinced by a series of high profile attacks, denial of service (DoS), or prevention of legitimate access to resources, is a threat that demands attention. Of particular concern are distributed attacks, in which an adversary recruits several computers to aid in the attack. The first major distributed denial of service (DDoS) attack brought down the University of Minnesota’s network for three ...

Distributed Denial of Service Defense Attack Tradeoff Analysis (DDOS-DATA)

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...

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...
