Analyzing the Security of Email Transmission in NS3 Through DDoS Attacks

Distributed Denial-of-Service (DDoS) attacks pose a significant threat to secure communication, potentially disrupting access to critical online services. Email transmission, which relies on TCP encryption protocols for security, can be heavily impacted by such attacks. This project aims to analyze the effects of DDoS attacks on secure email transmission using NS3 simulations. The study will model an email communication system employing TLS or SSL encryption and simulate different DDoS attack scenarios by varying attack intensity and traffic patterns. Performance metrics such as throughput, latency, and packet loss will be evaluated using NS3’s FlowMonitor module. The goal of this research is to assess the resilience of secure email systems under DDoS conditions and identify strategies to optimize network performance and mitigate attack impacts.
