A survey on resource inflated Denial of Service attack defense mechanisms

摘要

Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks are major threat to the internet and is a serious cyber crime. The rapid increase in number of people using internet and the development of technology has given birth to new virus and worms which can exploit our system. Attackers use the latest techniques to perform DoS attacks. There are numerous tools to perform DoS attack from millions of compromised system and can mess up any system or network in short period of time. There are many well known counter measures available like puzzle based defense mechanism. However an attacker can inflate the ability of DoS attack in solving the puzzle by using cheap and widely available GPUs. In this work, we provide a simple theoretical investigation and analysis of resource inflation attack defending mechanisms.
