DIY Protection Strategies

Self-implemented protections complement professional services for comprehensive defense. Start with proper server configuration to resist common attacks. Adjust kernel parameters to handle SYN floods more effectively. Enable SYN cookies, increase connection queues, and reduce timeout values. These free configurations significantly improve attack resistance.

Web server hardening prevents application-layer attacks from overwhelming resources. Configure connection limits per IP address to prevent single sources from monopolizing resources. Implement request rate limiting to block rapid-fire attacks. Enable caching headers to reduce backend load. These configurations require only time investment while providing substantial protection.

Firewall rules block obvious attack traffic before it impacts services. Create rules blocking unused ports and protocols. Implement geographic restrictions if serving only local markets. Rate limit ICMP to prevent ping floods. While not stopping sophisticated attacks, basic firewall rules eliminate many automated assaults.

Content optimization reduces attack surface and improves legitimate performance. Minimize dynamic content requiring backend processing. Implement aggressive caching for static resources. Optimize images and enable compression. Simplified sites withstand attacks better while providing superior user experience. These optimizations cost nothing while delivering multiple benefits.
