Mitigation of Denial of Service (DoS) Attack

Abstract

The recent Denial of Service (DoS) attacks against high-profile web sites shows how overwhelming DoS attacks are and how unprotected the Internet is under such attacks. We present a survey of the current proposed mitigations against Denial of Service (DoS) attacks that give a promising approach to the field. Weaknesses of the available methods are also presented which result to the fact that no unified method has been adopted yet. We also make a discussion about the future trends in DoS defense. In fact DoS is technical attack therefore can be handled only by knowing its technical aspects. Most commonly targeted application are DNS servers, Websites, E-commerce applications, online gaming, VOIP services by blocking customer’s access to these applications.
