A STUDY ON DENIAL OF SERVICE (DOS) AND DISTRIBUTED DENIAL OF SERVICE (DDOS) ATTACKS

  • Akash Hegde et al.

Abstract

A Denial of Service (DoS) attack is a type of cyber-attack wherein the attacker cripples the users
of a machine or a network by making it unavailable temporarily or disrupting the services of a
host indefinitely. A Distributed Denial of Service (DDoS) attack is a type of DoS attack in which
there are multiple sources for the attack and these sources can flood the target with unnecessary
packets, thereby bringing down the target. It is extremely difficult to stop DDoS attacks because
it involves multiple sources and blocking a single source is ineffective. In this paper, a thorough
study of the existing types of DDoS attacks and their defense mechanisms is presented. Scope for
future work in terms of defending against such large-scale attacks is also provided.
