On Distributed Denial of Service Current Defense Schemes

Denial-of-Service & Distributed Denial-of-Service on The Internet

Denial-of-Service and Distributed Denial-of-Service is costing the economy world-wide billions of dollars. The economy is the cornerstone of our society and its collapse will certainly change the way in which humanity exists today. The three main goals of computer security are availability, confidentiality and integrity. The focus of this paper is on attacks that compromise the availability of ...

Characterization of defense mechanisms against distributed denial of service attacks

We propose a characterization of distributed denial-of-service (DDOS) defenses where reaction points are network-based and attack responses are active. The purpose is to provide a framework for comparing the performance and deployment of DDOS defenses. We identify the characteristics in attack detection algorithms and attack responses by reviewing defenses that have appeared in the literature. ...

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

A Probabilistic Defense Mechanism Against Distributed Denial of Service Attacks

Distributed denial of service attacks form a prolific threat to any form of client-server computing, as used, for instance, by e-commerce businesses. The resources of standard servers are quickly consumed under such an attack, making them unavailable to legitimate users. We describe and analyze a defense mechanism for such servers. We prove that this mechanism favors benign users, making the se...

Distributed Denial of Service:

Distributed Denial of Service (DDoS) attacks have become a large problem for users of computer systems connected to the Internet. DDoS attackers hijack secondary victim systems using them to wage a coordinated large-scale attack against primary victim systems. As new countermeasures are developed to prevent or mitigate DDoS attacks, attackers are constantly developing new methods to circumvent ...
