## Popis

Secure Owl Firewall is a fast, lightweight firewall plugin with an advanced rule
engine featuring PCRE pattern matching, a transformation pipeline, and JSON-based
rule configuration.

Key features:

 * JSON-based rules — 100+ default rules covering SQLi, XSS, RCE, LFI, SSRF, Log4Shell,
   and more
 * Transformation pipeline — URL decode, lowercase, normalize path, remove whitespace,
   HTML entity decode, trim
 * Inspection targets — REQUEST_URI, QUERY_STRING, USER_AGENT, REFERER, COOKIE, 
   and POST
 * MU-Plugin loader — runs before regular plugins for earliest protection
 * Rate limiting — optional transient-based IP and subnet banning
 * Login protection — PIN field, speed limit and honeypot to block brute-force attacks
 * IP whitelist — CIDR/subnet support for both IPv4 and IPv6
 * IP blacklist — CIDR/subnet support for both IPv4 and IPv6
 * Per-rule toggle — disable individual rules from the admin panel without editing
   files
 * File-based logging — 64MB cap with auto-rotation and protected storage
 * Log retention — configurable policy for GDPR compliance
 * IP anonymization — masks user IP addresses for enhanced privacy and GDPR compliance

### Filter Hooks

 * `sswaf_ip_whitelist` — array of IPs to bypass the firewall
 * `sswaf_ip_blacklist` — array of IPs to block before any rules run
 * `sswaf_trusted_proxies` — array of trusted proxy IPs for X-Forwarded-For
 * `sswaf_post_scanning` — enable POST data inspection (default: true)
 * `sswaf_rules_file` — path to the rules JSON file
 * `sswaf_log_file` — path to the log file
 * `sswaf_log_max_size` — maximum log size in bytes
 * `sswaf_header_status` — HTTP status header for blocked requests
 * `sswaf_before_block` — action hook fired before blocking a request
 * `sswaf_rate_limit_ip_threshold` — override IP hit threshold
 * `sswaf_rate_limit_ip_duration` — override IP ban duration
 * `sswaf_rate_limit_ip_window` — override IP counting window
