- **Orange (6-10):** Warning - Schedule updates soon
- **Red (>10):** Critical - Update immediately

### Active Sessions
- **Normal:** 1-10 per user (multi-device)
- **Warning:** >20 sessions (investigate)
- **Action:** Terminate suspicious sessions

### Failed Logins (1h)
- **Normal:** 0-5 (mistyped passwords)
- **Warning:** 5-10 (possible brute force)
- **Critical:** >10 (active attack)
- **Action:** Check IP addresses, consider IP blocking

### Locked Accounts
- **Normal:** 0-2 (legitimate lockouts)

## ⚠️ Incident Response

### Suspected Brute Force Attack
1. Go to Security Monitor
2. Check Failed Logins metric
3. Filter audit log by "login" + "failed"
4. Identify attacking IP address
5. Consider IP blocking (future feature)
6. Notify affected users

### Critical Vulnerability Found
1. Review vulnerability details
2. Check affected packages
3. Test update in development
4. Schedule maintenance window
5. Apply updates to production
6. Verify fix with rescan

### Account Compromise
1. Immediately lock affected account
2. Review audit log for user
3. Check for unauthorized actions
4. Force password reset
5. Enable 2FA requirement
6. Notify user via secure channel

## 📞 Support

### Common Issues

**Q: "Scan Vulnerabilities" button not working**
- **A:** Check backend logs, ensure npm is installed in container

**Q: Audit log empty**
- **A:** Wait for user activity, or check database table `security_audit_log`

**Q: Can't access /security/monitor**
- **A:** Verify admin role, check RBAC permissions

**Q: Translations not showing**
- **A:** Clear browser cache, restart frontend dev server

**Q: High false positive vulnerabilities**
- **A:** Review npm audit output, many are dev dependencies (safe in production)

- ✅ Vulnerability scan completes
- ✅ Audit log displays events
- ✅ Recommendations appear
- ✅ Exports work (JSON/CSV)
- ✅ All translations display
- ✅ Regular users blocked from admin features
- ✅ No breaking changes to existing functionality

## 🎯 Next Steps (Optional)

### Future Enhancements
1. **IP Blocking System** - Automatic blocking after repeated attacks
2. **Rate Limiting Dashboard** - Visual rate limit statistics
3. **Email Alerts** - Notify admins of critical events
4. **SIEM Integration** - Export to enterprise security systems
5. **Advanced Threat Detection** - ML-based anomaly detection
6. **Compliance Reports** - Automated SOC 2, GDPR reports

### Priority: Medium
- These are enhancements, not critical
- Current implementation covers core security needs
- Implement based on organizational requirements
