Nginx is a critical component in modern web infrastructure, often serving as the first line of defense against malicious traffic. This guide explores advanced configuration techniques to harden Nginx against common attack vectors such as DDoS, SQL injection, cross-site scripting (XSS), and brute-force login attempts. Key strategies include rate limiting, IP blacklisting, request filtering with ModSecurity, and proper SSL/TLS setup. The article also covers logging and monitoring to detect anomalies early. For DevOps and security teams, these practices are essential to maintain uptime and protect sensitive data. Implementing these measures can significantly reduce the attack surface and improve overall security posture without major architectural changes.
