Study And Performance Evaluation On Recent Ddos Trends Of Defense On Web Servers

Abstract

The traditional architecture of World Wide
Web is vulnerable to serious kinds of threats
including distributed denial of service (DDoS)
attacks. Denial of service (DoS) attacks are very
common in the world of internet today. The
attack aims to deny or degrade normal services
for legitimate users by sending huge traffic to the
victim (machines or networks) to exhaust services,
connection capacity or the bandwidth. The
attackers are now quicker in launching such
attacks because they have sophisticated and
automated DDoS attack tools available which
require minimal human effort, as such, there is
now an increasing pace of DDoS attacks; This has
made servers and network devices on the internet
at greater risk than ever before. Due to the
same reason, “organizations and people carrying
large servers and data on the internet are now
making greater plans and investigation to be
secure and defend themselves against a number
of cyber-attacks including Distributed Denial of
Service.”(A. Mitrokotsa, and C. Douligeris
[2006]).
