- Timeline: 1-3 hours to resolve
- Options:
  - Option A: Fix tower_governor types (1-2 hours)
  - Option B: Implement custom middleware (2-3 hours)
  - Option C: Use Redis-based rate limiting (3-4 hours)

**Firewall Rate Limiting (Temporary)**
- Install fail2ban on server
- Configure rules for /api/auth/login endpoint
- Monitor for brute force attempts

### MEDIUM PRIORITY - Within 30 Days

**TLS Certificate Auto-Renewal**
- Status: Manual renewal required
- Issue: Let's Encrypt auto-renewal not configured
- Action: Install certbot with auto-renewal timer
- Timeline: 2-4 hours
- Impact: Prevents certificate expiration

**Session Timeout UI**
- Status: Server-side expiration works, UI redirect missing
- Action: Implement JavaScript token expiration check
- Impact: Improved security UX
- Timeline: 2-4 hours

**Comprehensive Audit Logging**
- Status: Basic event logging exists
- Action: Expand to full audit trail
- Timeline: 2-3 hours
