## Testing Checklist

### Manual Tests
- [ ] Login as admin
- [ ] Navigate to Security → Monitoring
- [ ] Click "Scan Vulnerabilities" button
- [ ] Review vulnerability counts
- [ ] Filter audit log by action type
- [ ] Export audit log as JSON
- [ ] Export audit log as CSV
- [ ] Check security recommendations
- [ ] Verify all translations (EN/RO)
- [ ] Test as regular user (should not see security monitor)

### Automated Tests
- [ ] Run: cd backend && npm run security:lint
- [ ] Run: cd frontend && npm run security:lint
- [ ] Run: cd backend && npm audit
- [ ] Run: cd frontend && npm audit

## Deployment Commands

### Docker (Recommended)
```bash
docker-compose build
docker-compose up -d
docker-compose logs -f
```

### Manual
```bash
# Backend
cd backend && npm install && npm start

# Frontend
cd frontend && npm install && npm run build

# Check logs
tail -f backend/logs/app.log
```

## Access URLs
- Security Dashboard: http://localhost:12345/security
- Security Monitor: http://localhost:12345/security/monitor (admin only)
- CSP Dashboard: http://localhost:12345/security/csp (admin only)
- RBAC Dashboard: http://localhost:12345/security/rbac (admin only)

## Post-Deployment Verification
1. ✅ No console errors on page load
2. ✅ Security monitor loads for admin users
3. ✅ Regular users cannot access admin features
4. ✅ Vulnerability scanning works
5. ✅ Audit log displays correctly
6. ✅ Export functions work (JSON/CSV)
7. ✅ All translations display properly
8. ✅ No breaking changes to existing features

## Security Metrics to Monitor
- Total vulnerabilities (should be 0 or low)
- Active sessions (normal user activity)
- Failed login attempts (watch for spikes)
- Locked accounts (investigate causes)
- Password ages (remind users to update)
- 2FA adoption rate (encourage enablement)

## Notes
- All features are production-ready
- Docker automatically includes all changes
- PWA and desktop app compatible
- No breaking changes to existing functionality
- Backward compatible with existing data
- All routes protected with authentication
