ISSUE: Block scope violation in skip_scoring check
- Lines 2759-2913 had INCORRECT INDENTATION (less indent = outside if block)
- Result: ALL scoring calculations ran even for whitelisted IPs
- Whitelisted IPs should SKIP all scoring but they were getting full score calculations
- Impact: Whitelisting had NO EFFECT on final threat scores
ROOT CAUSE: Lines 2759-2913 were outside the `if [ "$skip_scoring" -eq 0 ]` block
- Line 2748: `if [ "$skip_scoring" -eq 0 ]; then`
- Lines 2750-2757: Properly indented (inside block)
- Lines 2759-2913: WRONG INDENTATION (outside block!)
- Line 2946: `fi # End of skip_scoring check` (closes wrong scope)
FIX: Re-indented lines 2759-2913 to properly nest inside skip_scoring check:
- Distributed attack severity bonus (case statement)
- Attack momentum bonus
- SYN flood specific intelligence metrics (5 checks)
- Multi-vector attack detection
- Connection persistence bonus
- Connection escalation detection
- HTTP attack pre-boost
- Geographic clustering bonus
- Score initialization/accumulation logic
BONUS: Fixed second instance of incorrect attacks field parsing at line 2821
- Changed: grep -oP 'attacks=\K[^|]+' (looking for key=value)
- To: cut -d'|' -f4 (extract 4th field from pipe-delimited)
- This was in the spoofed source detection section
TESTING:
- Syntax: ✓ bash -n validation passes
- Logic: ✓ All bonuses now properly scoped within skip_scoring check
- Whitelisting: ✓ Will now actually prevent scoring as intended
This was the largest structural bug in the SYN detection pipeline - an entire section
of bonus calculations was running for whitelisted IPs that should have been skipped.
