Network Performance Analysis and DoS Attack Mitigation Strategy on MikroTik Router for Optimal Stability

The router, as a gateway in the network, plays a vital role. If its functionality is disrupted by Denial of Service (DoS) attacks, which pose a serious cyber threat and have destructive effects by overwhelming the target with large amounts of traffic, it directly impacts network performance. This research aims to analyze DoS attacks on network devices based on MikroTik routers and switches, which become targets that disrupt network traffic. These attacks lead to a significant increase in data traffic, affecting the stability and performance of the network. Through analysis using network forensic methods, this study evaluates the performance of MikroTik firewalls in mitigating DoS attacks by assessing the traffic received and rejected based on applied rules. The results show that the firewall can handle most attacks; however, some suspicious packets still bypass it. This study emphasizes the importance of enhancing security systems and mitigating DoS attacks to maintain optimal network performance in the future.
