Practical OWASP CRS In High Security Settings
summary
CRS 3.2 plus ModSecurity on Apache proves able to stop active testers even when backend code is broken: Burp sends 4.5 million requests, default CRS already removes most LFI and XSS and greatly reduces SQLi, and a 900-attacker bug‑bounty yields only 16 findings with highest severity low. Practical ingredients are ModSecurity 2.9 on Apache, paranoia level tuning (150 rules → ~200 at higher levels), anomaly scoring to iterate from monitoring to blocking, and fail2ban integration to cut off scanners.
