ModSecurity is a powerful open-source WAF that can combine IP reputation data with request inspection for layered protection.
What is ModSecurity?
ModSecurity is an embeddable WAF engine that works with Apache, Nginx, and IIS to inspect and block malicious requests.
Custom Rules
Create SecRules to match against IP collections loaded from blocklist files.
IP Collection Loading
Load IP blocklists into ModSecurity collections for efficient matching in rules.
Best Practices
- OWASP CRS - Combine IP blocking with OWASP Core Rule Set.
- Anomaly Scoring - Add IP matches to overall anomaly scores.
- Logging - Log blocked requests with full details.
