ABSTRACT
This paper conducts a detailed study on the simulation and analysis of Denial of Service (DoS) attacks using Network Simulator 2 (NS2). DoS attacks, characterized by malicious attempts to disrupt or limit access to network resources, pose a significant threat to the availability and reliability of computer networks. The research focuses on utilizing NS2 as a simulation platform to emulate various types of DoS attacks, assessing their impact on network performance, and evaluating potential countermeasures.
The simulation scenarios encompass different DoS attack vectors, including flood-based attacks and protocol-specific attacks, to analyze their effects on key network metrics such as packet loss, throughput, and latency. The study also explores the effectiveness of intrusion detection and prevention mechanisms as countermeasures to mitigate the impact of DoS attacks.
The paper outlines the design and implementation details of the NS2 simulation setup, emphasizing the replication of realistic network conditions and attack scenarios. Results from the simulations contribute valuable insights into the vulnerabilities of network protocols and the effectiveness of countermeasures in the face of DoS attacks.
