manual process + +--- + +## Maintenance Tasks + +### Daily (First Week) +- [ ] Check for unusual login patterns in audit_logs +- [ ] Monitor error logs for CSRF/rate limiting issues +- [ ] Confirm audit_logs table growing normally + +### Weekly +- [ ] Review top 10 failed login attempts + ```sql + SELECT email, COUNT(*) as attempts + FROM audit_logs + WHERE action = 'login_failure' + AND created_at > DATE_SUB(NOW(), INTERVAL 7 DAYS) + GROUP BY email + ORDER BY attempts DESC + LIMIT 10; + ``` + +### Monthly +- [ ] Review audit log growth rate +- [ ] Archive old logs if needed (keep 6+ months) +- [ ] Check database performance metrics + +### Quarterly +- [ ] Review failed login patterns for brute force attempts +- [ ] Verify rate limiting thresholds still appropriate +- [ ] Check if any forms missed CSRF tokens + +--- + +## Next Steps (Phase 3 - Optional) + +Once Phase 2 is stable (1-2 weeks), consider Phase 3: + +- **Two-Factor Authentication (2FA)** + - TOTP (Google Authenticator) support + - SMS backup codes + - Recovery codes for account lockouts + +- **Login Notifications** + - Email alerts on new device login + - IP address tracking per session + - Device fingerprinting + +- **Advanced Audit Features** + - Login attempt heatmaps + - Geographic tracking + - Browser/OS fingerprinting + - Suspicious activity alerts + +--- + +## Support & Questions + +### Common Questions + +**Q: Will this break existing functionality?** +A: No. Phase 2 is 100% backward compatible. All features work exactly as before. + +**Q: What if rate limiting blocks legitimate users?** +A: After 15 minutes (login) or 30 minutes (password reset), the block resets automatically. + +**Q: How much disk space will audit logging use?** +A: ~100-200 MB per year for typical site usage. Negligible impact. + +**Q: Can I adjust rate limiting thresholds?** +A: Yes. Edit RateLimitMiddleware.php constants (RATE_LIMIT_LOGIN = 5, TIME_WINDOW_LOGIN = 900). + +**Q: What if the database fails during login?** +A: AuditLogger gracefully catches errors. Users can still log in. Audit logging silently fails. + +### For Issues + +1. Check `DATABASE_MIGRATION_GUIDE.md` troubleshooting section +2. Review error logs (`error_log` file) +3. Check audit_logs table for patterns +4.
