31801a6c1d Make scan detection more targeted to avoid false positives
All checks were successful
HAProxy Manager Build and Push / Build-and-Push (push) Successful in 52s
Details 
Major changes to prevent legitimate users from being blocked:

1. Increased thresholds significantly:
   - Initial trigger: 10 → 25 errors
   - Medium level: 20 → 40 errors
   - High level: 35 → 60 errors
   - Critical level: 50 → 100 errors

2. Only count actual scan attempts as errors:
   - Script files: .php, .asp, .jsp, .cgi, .pl, .py, .rb, .sh
   - Admin paths: /wp-admin, /phpmyadmin, /adminer
   - Config files: .env, .git, .htaccess, .ini, .yml
   - Backup files: .backup, .bak, .sql, .dump
   - Known vulnerable paths: /cgi-bin, /fckeditor

3. Explicitly exclude legitimate assets from counting:
   - Images: .jpg, .png, .gif, .svg, .webp
   - Fonts: .woff, .woff2, .ttf, .eot, .otf
   - Static: .css, .js, .map, .pdf
   - Common paths: /static/, /assets/, /fonts/, /images/

4. Still count all 401/403 errors (auth failures are suspicious)

This prevents missing fonts, images, CSS files from triggering blocks
while still catching actual vulnerability scanners.

6a4379c4a1 Add safeguards to prevent false positive blocking
All checks were successful
HAProxy Manager Build and Push / Build-and-Push (push) Successful in 52s
Details 
- Handle common missing files (favicon.ico, robots.txt) without counting as errors
- Return 404 directly from frontend for these files (bypasses backend counting)
- Add clear-ip.sh script to remove specific IPs from stick-table
- Keep trusted networks whitelist for local/private IPs

This prevents legitimate users from being blocked due to browser
requests for common files that don't exist.

Usage: ./scripts/clear-ip.sh <IP_ADDRESS>

e54b4b4afe Implement progressive protection: tarpit → silent-drop → block
All checks were successful
HAProxy Manager Build and Push / Build-and-Push (push) Successful in 1m20s
Details 
- Set tarpit timeout to 10 seconds for initial offenders
- Use silent-drop for obvious scanners (35+ errors) and repeat offenders
- Silent-drop immediately closes connection without response
- Keep 429 block for critical threats (50+ errors)

Protection levels:
- 10-19 errors: 10s tarpit
- 20-34 errors: 10s tarpit (first), silent-drop (repeat)
- 35-49 errors: silent-drop
- 50+ errors: 429 block
- Burst attacks: 10s tarpit (first), silent-drop (repeat)

Updated monitoring script to show correct status based on new logic.

b88da4c58f Implement HAProxy tarpit escalation and CLI monitoring
All checks were successful
HAProxy Manager Build and Push / Build-and-Push (push) Successful in 51s
Details 
- Add full tarpit escalation logic with gpc1 tracking (levels 0-3)
- Implement progressive delays: 2-5s → 8-15s → 20-45s → 60s
- Increase initial threshold from 5 to 10 errors (more tolerant)
- Reduce tracking duration from 2h to 1h (faster cleanup)
- Add show-tarpit-ips.sh script for monitoring tarpitted IPs via CLI
- Script shows IP, scan count, escalation level, and tarpit status
