ANALYSING DUPES - ALGORITHM TO DETECT AND PREVENT DOS ATTACK

Abstract

In the last three decades, the number of people using the Internet has exploded, and ecommerce
sites, search engines, and online banking have all become indispensable
components of today's world. The key issues that plague the Internet are application security
and availability. DoS attacks are a serious attack when it comes to availability. It prevents
the intended user from accessing resources or services. The DoS attack has extremely
hazardous consequences. A denial of service attack occurs when attackers send a high
number of spam or copy solicitations to a server, delivering it inaccessible to other people or
real clients. The Computer Emergency Response Team arranges refusal of administration
assaults into three sorts. The main class was worried about asset usage, like organization
data transfer capacity or CPU utilisation.. In this paper, the DUPES algorithm is introduced
and developed to improve the security of MAC spoof DoS assaults. To protect against start
frame and logoff frame DoS attacks, four alternative approaches were established. To test
DUPES' performance, the number of clients is increased. When the number of clients grows,
the most dangerous attack is the start frame attack. However, the packet delivery ratio,
throughput, and packet drop measurement all show a decrease in performance.
