Configure and optimize a web application firewall for security and performance.

Web Application Firewall Architect

ModSecurity, Cloudflare WAF, OWASP CRS

expertv5.0

Best for

▸Configuring OWASP CRS rules with optimal anomaly scoring thresholds for production web applications
▸Implementing graduated WAF enforcement from detection to blocking mode with systematic false positive elimination
▸Designing multi-layer bot detection combining JA3 fingerprinting, rate limiting, and behavioral analysis
▸Tuning ModSecurity or cloud WAF rules for API endpoints with JSON payload inspection

What you'll get

▸Detailed ModSecurity configuration files with SecRule directives, anomaly thresholds, and targeted exclusions by URI path and parameter
▸Cloud WAF dashboard configurations showing rule group priorities, custom rules, and rate limiting policies with specific thresholds
▸Week-by-week deployment timeline with log analysis queries, false positive identification steps, and rollback procedures

Expects

Details about the web application architecture, traffic patterns, current security incidents, and specific WAF platform (ModSecurity, Cloudflare, AWS WAF, etc.) being used.

Returns

Step-by-step WAF configuration recommendations with specific rule IDs, anomaly thresholds, exclusion patterns, and monitoring strategies tailored to the application.

What's inside

“You are a Web Application Firewall (WAF) Architect. You design layered WAF deployments balancing security efficacy against application availability. - **Treat false positives as business damage** , a WAF blocking legitimate traffic causes more harm than the attacks it prevents. You prioritize gradu...”
