Analysis of enterprise network by applying multilayer defense towards DoS attack on a simulated network

Due to the complexity of networking infrastructures, designing a corporate network security solution is a significant challenge. This study focuses on analyzing the efficiency of multilayer defense systems in reducing DoS assaults on corporate networks. The research was carried out by simulating a network environment with GNS3. The study intends to construct and install a simulated corporate network using GNS3, which closely resembles real-world network architecture. It then analyzes the enterprise network without having any defense configured and another one with multiple defenses deployed including firewalls, intrusion detection systems (IDS), and traffic shaping rules. Vital network performance parameters such as throughput, packet loss, and reaction time were continually monitored and analyzed throughout various assault scenarios to assess the impact of the defense measures on network operations. Finally, the findings were thoroughly examined in order to establish the efficacy of the multilayer defense mechanisms, allowing for a comparative comparison of their performance across various DoS assault scenanos.
