shadowdaoandClaude	0ee9e6cba8	Remove all ACL-to-ACL references for HAProxy 3.0.11 compatibility ... Final fix for HAProxy 3.0.11 syntax requirements: ACL Reference Resolution: - Removed all compound ACLs that referenced other ACLs - Updated all http-request rules to use base ACLs directly - HAProxy 3.0 does not allow ACL-to-ACL references Direct Base ACL Usage: - bot_scanner: Scanner user agent detection - scan_admin: Admin path scanning - scan_shells: Shell/exploit attempts - sql_injection: SQL injection patterns - directory_traversal: Path traversal attempts - wp_403_abuse: WordPress 403 failures - rate_abuse: Rate limit violations - suspicious_method: Dangerous HTTP methods - missing_accept_header: Missing browser headers - blacklisted: Blacklisted IPs - auto_blacklist_candidate: Auto-ban candidates Graduated Response System (Direct ACL Based): - Low threat (info): rate_abuse, suspicious_method, missing headers - Medium threat (warning + tarpit): sql_injection, directory_traversal, wp_403_abuse - High threat (alert + deny): bot_scanner, scan_admin, scan_shells - Critical threat (alert + deny): blacklisted, auto_blacklist_candidate Monitoring Updates: - Updated log parsing for base ACL names - Enhanced threat classification in monitoring scripts All syntax is now pure HAProxy 3.0.11 compatible while maintaining comprehensive security protection with graduated responses. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-09-22 17:44:44 -07:00
shadowdaoandClaude	ee8223c25f	Complete HAProxy 3.0.11 syntax fixes for ACL and sc-inc errors ... Fixed remaining HAProxy 3.0.11 compatibility issues: ACL Definition Fixes: - Fixed compound ACL references (can't reference ACLs as fetch methods) - Split complex ACLs into individual threat detection ACLs - Updated all ACL names to be descriptive and unique Syntax Corrections: - Fixed sc-inc-gpc syntax (removed extra "1" parameter) - Updated all ACL references in http-request rules - Fixed compound conditions in response rules Threat Detection Structure: - high_threat_detected: Bot scanners - high_threat_scan: Admin path scanning - high_threat_shells: Shell/exploit attempts - medium_threat_injection: SQL injection attempts - medium_threat_traversal: Directory traversal - medium_threat_wp_attack: WordPress brute force (403s) - low_threat_rate: Rate limit violations - low_threat_method: Suspicious HTTP methods - low_threat_headers: Missing browser headers - critical_threat_blacklist: Blacklisted IPs - critical_threat_autoban: Auto-blacklist candidates Response System Updates: - Individual ACL-based responses for each threat type - Proper whitelisting for legitimate bots/browsers - Enhanced logging with new threat classifications Monitoring Script Updates: - Updated log parsing for new threat level names - Better threat categorization in real-time monitoring All syntax errors resolved for HAProxy 3.0.11 compatibility while maintaining comprehensive security protection. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-09-22 17:37:16 -07:00
