Abstract
Distributed Denial of Service (DDoS) attacks pose a significant threat to the availability of web server services. This study aims to evaluate the effectiveness of combining ModSecurity OWASP Core Rule Set (CRS) and DDoS Deflate in detecting and mitigating DDoS attacks. The research was conducted in a controlled laboratory environment using three scenarios: without protection, with ModSecurity alone, and with a combination of ModSecurity and DDoS Deflate. The testing involved simulated HTTP Flood and SYN Flood attacks over a duration of 10 minutes, with performance metrics observed using Prometheus, Grafana, and tcpdump. The results indicate that in the unprotected scenario, server CPU usage spiked up to 97%, accompanied by a high volume of incoming traffic without any mitigation. The implementation of ModSecurity alone provided limited protection, primarily at the application layer, by partially blocking HTTP requests. In contrast, the combined use of ModSecurity and DDoS Deflate significantly improved mitigation effectiveness, successfully blocking over 5 million malicious connections and achieving a bandwidth efficiency of 87.76% against HTTP Flood attacks. In conclusion, the layered mitigation approach demonstrated a superior ability to maintain server performance stability and is highly recommended as a strategy for protecting web servers from DDoS attacks.
