## 🔄 Migration Threat Considerations

### **Transition Period Risks**

During the migration from stdio to cloud-native architecture, specific transition threats must be managed:

| Transition Risk | Description | Mitigation | Timeline |
|----------------|-------------|-----------|----------|
| **Dual-mode operation** | Running both stdio and cloud endpoints increases attack surface | Feature flags, phased rollout, separate security monitoring | Phase 1-2 |
| **Credential migration** | Moving from no-auth to OAuth2 introduces credential management complexity | Gradual auth enforcement, backward-compatible API | Phase 1 |
| **Data migration** | Moving from in-memory cache to DynamoDB introduces data persistence risks | Encryption at rest from day one, minimal data retention | Phase 2 |
| **Configuration drift** | IaC and manual configuration divergence during migration | Terraform/CDK enforcement, drift detection, compliance scans | Phase 2-3 |
